Rallye Seat Frame and Foam Kit - 5 Point Seat Belt

Sold each

This R Seat frame and foam kit provides an untrimmed, fixed-back bucket-seat foundation for Porsche 911, 964 and 914 applications from 1965–94. Prepared for a 5-point belt arrangement, it allows a chosen upholstery specialist to complete the covering in materials and details suited to the vehicle. 

Fits

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

The seat-shell concept separates the supporting structure and shaped padding from the final upholstery. The kit supplies the principal components needed to establish the seat profile, while the covering material, colour, stitching and finishing work can be completed locally. This approach makes it possible to coordinate the finished seat with a restored, period-style or individually specified interior.

The R Seat shape is based on the supportive seats associated with early rally and racing cars. Its fixed bucket form creates defined back, side and cushion support while retaining an appearance appropriate for a classic Porsche cabin. Duralastic suspension belts provide a flexible base beneath the cushion rather than relying on foam alone.

Functions

• Forms the structural foundation for a fully upholstered R Seat
• Uses shaped foam to establish the backrest, side and cushion profile
• Supports the seat cushion through flexible Duralastic suspension belts
• Provides dedicated openings for a 5-point belt arrangement
• Allows the final upholstery specification to be selected separately
• Creates a fixed seating position determined by the mounting installation

Technical Details

• Kit includes the seat frame, Duralastic belt set, side and backrest foams, cushion foam and 5-point belt rosette set
• Coated steel tube frame construction
• Fire-resistant foam padding
• Approximately 385 mm side-to-side mounting distance
• Fixed, non-adjustable seat structure
• Final seat height and backrest angle are established through the mounting arrangement

Symptoms of Fault

• Seat foam has collapsed, split or become uneven
• The existing seat no longer provides consistent back or side support
• Suspension components have stretched and allow the cushion to sag
• The frame has corrosion, distortion or unwanted movement
• Damaged upholstery and padding require a complete seat rebuild
• The current seat is unsuitable for the planned 5-point belt layout

Why Replacement Matters

Renewing the frame, suspension and padding together gives the upholsterer a sound foundation for the finished seat. It avoids placing new trim over deteriorated foam or tired supporting components and enables the seat position to be set for the vehicle and driver during installation. All belt anchorages and seat mountings should be installed using suitable hardware and checked by a competent specialist.

FAQs

• Is upholstery supplied? No. The frame, suspension and foam components are provided for finishing by an upholstery specialist.
• Can the backrest be adjusted? No. This is a fixed seat structure, so its installed height and angle depend on the selected mounting arrangement.
• Is this version prepared for 5-point belts? Yes. It has the relevant belt openings and includes the corresponding rosette set.
• Can it be fitted to a Porsche 914? The supplied application includes the Porsche 914 when used with an appropriate slider or tilting bracket.

• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

The seat shell kit concept separates the seat’s supporting structure, suspension and shaped padding from its final upholstery. The essential underlying components are supplied as a kit, allowing a professional automotive trimmer to finish the seat in leather, vinyl, fabric or another suitable material. Colour, stitching, piping and other upholstery details can therefore be selected to complement the vehicle’s existing cabin or restoration specification.

The R Seat design is based on the supportive driver and co-driver seats associated with early rally and competition cars. Its shaped, fixed-back form provides defined support around the backrest, sides and cushion while retaining a period-style appearance appropriate for a classic Porsche interior. Duralastic suspension belts sit beneath the cushion to provide flexible support rather than relying on the foam alone.

Functions

• Provides the structural shell for a complete upholstered R Seat
• Uses shaped foam sections to establish the seat profile
• Supports the cushion with flexible Duralastic suspension belts
• Allows upholstery materials, colours and stitching to be specified separately
• Creates a fixed seating position determined by the chosen mounting installation
• Provides a period-style seat form for classic Porsche interior restoration

Technical Details

• Kit includes the seat shell, Duralastic suspension belts, side and backrest foam, seat cushion and headrest
• Fibreglass seat shell construction
• Fixed-back bucket-seat design
• Untrimmed components ready for professional upholstery
• Version specified for use with 3-point seat belts
• Mounting brackets, runners and upholstery should be confirmed separately for the installation

Symptoms of Fault

• Original seat foam has collapsed, split or lost its shape
• The seat cushion sags or provides uneven support
• The existing frame or shell is corroded, distorted or damaged
• Backrest and side support have deteriorated through age and use
• Worn upholstery reveals degraded foam or supporting components
• A complete foundation is required for a seat restoration project

Why Replacement Matters

Replacing the supporting shell, suspension and foam together gives the upholsterer a consistent foundation for the finished seat. This avoids fitting new trim over deteriorated padding or tired suspension parts and allows the upholstery specification to be coordinated with the rest of the interior. Seat brackets, runners and belt anchorages are safety-critical; installation should use appropriate hardware and be checked by a suitably experienced specialist.

FAQs

• Is the upholstery included? No. The kit is supplied untrimmed so the covering material and finishing details can be selected separately.
• What is included in the shell kit? It includes the seat shell, Duralastic suspension belts, shaped side and backrest foam, seat cushion and headrest.
• Can the backrest angle be adjusted? No. This is a fixed-back seat, so the installed height and angle are established by the selected brackets and mounting arrangement.
• Is this the 3-point seat-belt version? Yes. This kit is specified for a 3-point belt arrangement rather than a multi-point harness configuration.
• Does it fit a Porsche 914? The supplied application includes the Porsche 914, subject to the use of suitable model-specific runners or mounting brackets.

Rallye Seat Frame and Foam Kit - 3 Point Seat Belt

Sold each

Rallye Seat Frame and Foam Kit by Retro Trim for classic Porsche 911, 964 and 914 models from 1965 to 1994. This version is intended for use with a 3-point seat belt and is supplied without a seat-belt cut-out rosette set. 

Fits

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1975-1977 3.0L Turbo (930)
• Porsche 911 1978-1989 3.3L Turbo (930)
• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

This kit provides the untrimmed structure, flexible suspension and shaped padding needed to create a complete fixed-back Rallye seat. Its tall backrest and raised side bolsters reflect the form of competition-influenced sports seats used in European cars during the late 1960s and early 1970s. The seat can be finished by a local automotive trimmer, allowing the upholstery, stitching and detailing to be coordinated with the vehicle’s interior.

Functions

• Provides the structural foundation for an upholstered Rallye seat
• Uses flexible Duralastic supports beneath the occupant
• Forms the seat base, backrest and side-bolster profile
• Supports a low seating arrangement when installed appropriately
• Allows upholstery materials and finishing details to be selected separately
• Accommodates the vehicle’s standard 3-point belt arrangement

Technical Details

• Tubular steel frame with a protective coating
• Duralastic suspension system
• Shaped base, backrest and bolster foam components
• Fire-retardant padding specification
• Approximately 385 mm mounting distance from side to side
• Fixed backrest; final seat height and rake are determined by the installation

Frame Kit Concept

Supplying the seat in component form enables the trimming work to be carried out by a chosen upholstery specialist. The prepared frame, suspension and foam establish the required seat shape before the covering is fitted. This approach makes it possible to select leather, vinyl or fabric that suits the existing cabin while avoiding the need to transport a finished seat for retrimming. Mounting hardware, sliders or tilting arrangements should be selected to suit the individual vehicle and desired seating position.

Symptoms of Fault

• Original seat foam has sagged, split or lost its shape
• The existing seat no longer provides even back or side support
• Internal suspension elements have stretched or detached
• Corrosion, cracking or movement is present in the old frame
• Worn covers and padding require a complete seat rebuild
• The current seating height or profile is unsuitable for the restoration

Why Replacement Matters

Renewing the frame, suspension and foam together gives an upholsterer a consistent base on which to build the finished seat. It avoids applying new coverings over collapsed padding or a damaged structure and allows the mounting position to be established for the vehicle and driver. As the backrest is not adjustable, installation should account for the required height, rake and access before the upholstery work is completed.

FAQs

• Is upholstery included? No. The kit is designed to be covered and finished by an automotive upholstery specialist.
• Does this version have harness openings? No. It is the 3-point belt version and does not include a seat-belt cut-out rosette set.
• Can the backrest angle be adjusted? The seat itself is fixed. Height and rake are set through the chosen mounting arrangement.
• Can it be fitted to a Porsche 914? The frame is suitable for the listed 914 application when used with an appropriate mounting or tilt-and-slider arrangement.

Sold each

This Rallye seat frame and foam kit provides the structural and padded foundation for a period-style competition seat in classic Porsche 911, 964 and 914 models. Configured for 5-point belts, it can be upholstered locally in materials selected to complement the vehicle's existing cabin. Sold each

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

The kit combines a coated steel tube frame with Duralastic suspension belts and shaped foam components. Its fixed bucket-seat profile is based on the rally and sports seats fitted to European performance cars during the late 1960s and early 1970s. A taller back and raised side supports help establish a supportive seating shape while retaining an appropriate appearance for a classic interior.

Functions

• Forms the structural basis of a complete upholstered Rallye seat
• Provides shaped side, backrest and cushion padding
• Supports the occupant through a flexible Duralastic belt system
• Accommodates a 5-point belt installation through dedicated openings
• Allows the upholstery material and finish to be selected locally
• Creates a relatively low seating position when correctly installed

Technical Details

• Kit includes seat frame, Duralastic belt set, side and backrest foams, seat cushion foam and 5-point seat belt rosette set
• Coated steel tube frame construction
• Fire-retardant padding specification
• Approximately 385 mm side-to-side mounting distance
• Fixed, non-adjustable seat structure; installation determines the final height and tilt
• Wide, tall seat profile intended to accommodate a broad range of drivers

Frame Kit Concept

Supplying the seat as a frame and foam kit enables the trimming work to be completed by a chosen upholstery specialist. This allows the covering material, colour, stitching and finishing details to be coordinated with the rest of the interior without transporting a fully trimmed seat. The pre-shaped foam and suspension components provide the starting profile required by the trimmer.

Symptoms of Fault

• Collapsed, uneven or deteriorated seat foam
• Insufficient support from worn original seat padding
• Movement, corrosion or damage within an existing seat frame
• Torn upholstery or separated seams requiring a complete rebuild
• Loose suspension components causing sagging or unwanted movement
• A seating position unsuitable for a planned 5-point belt installation

Why Replacement Matters

Worn frames, suspension belts and foam can affect seating position, comfort and support. Rebuilding the seat from a prepared frame kit provides an opportunity to renew the structural and padded elements together, rather than fitting new upholstery over tired components. The fixed frame must be mounted at a suitable height and angle for the individual vehicle and driver.

FAQs

• Does the kit include upholstery?
  No. It supplies the frame, suspension components and foam required for finishing by an upholstery specialist.
• Can the backrest angle be adjusted?
  The seat structure is fixed. The preferred seating height and angle must be established through the mounting arrangement.
• Is it prepared for 5-point belts?
  Yes. This version includes the relevant belt openings and a 5-point rosette set. Use appropriate mounting points and follow the belt supplier's installation instructions.
• Can it be installed in a Porsche 914?
  The Rallye frame design uses a mounting layout intended to support installation in the 914 with the appropriate tilt or slider bracket.

• Porsche 911 1965-1968 2.0L / 912 SWB (F)

Diagram ref no 3

Although small, this component is an important finishing detail that helps maintain both the functionality and appearance of the rear interior.

What Does the Rear Seat Strap Locking Hook Do?

The locking hook provides a secure fixing point for the rear seat retaining strap. Once fastened, it holds the folding rear seat back in its correct position, preventing unwanted movement while driving and maintaining a neat, factory-correct interior.

Why Do Rear Seat Strap Hooks Fail?

After decades of use, these hooks are often affected by:

• Worn or damaged chrome plating
• Corrosion and surface pitting
• Accidental damage
• Bent or distorted hooks
• Missing components during previous repairs or restorations

A damaged or missing hook prevents the rear seat strap from securing correctly and detracts from the originality of the interior.

When Should It Be Replaced?

Replacement is recommended if the hook is:

• Missing
• Corroded or heavily pitted
• Bent or damaged
• Loose or no longer securing the strap correctly
• Being renewed as part of an interior restoration

Replacing worn interior hardware is an easy way to restore both the function and presentation of your classic Porsche.

Porsche 911 Interior Restoration Components

Attention to detail is what sets an exceptional Porsche restoration apart. Small interior fittings such as seat strap hooks, trim fixings and chrome hardware play an important role in recreating the original factory finish while ensuring every component functions correctly.

OE Match interior components offer excellent quality and factory-style fitment, making them ideal for restoring classic Porsche interiors to their original condition.

Benefits of Replacing the Rear Seat Strap Locking Hook

• Restores correct rear seat operation
• Secures the rear seat retaining strap
• Refreshes the interior appearance
• Replaces corroded or damaged original hardware
• Ideal for concours restorations

What This Product Does

A seat shell kit separates the supporting structure, suspension and shaped foam from the finished upholstery. Supplying these underlying components together gives an automotive trimmer a prepared base on which to apply leather, vinyl, fabric or another suitable covering. The colour, stitching, piping and other details can therefore be selected to suit a restoration, restomod or existing cabin specification.

The RSR design takes inspiration from the lightweight seats associated with Carrera RS and RSR applications. Its shaped bucket profile provides defined support around the cushion, backrest and sides while retaining a classic competition-style appearance. Duralastic belts beneath the cushion create a flexible supporting platform instead of relying entirely on the foam.

Functions

• Provides the structural foundation for a complete upholstered seat
• Uses shaped foam to form the cushion, sides and backrest
• Supports the cushion through flexible Duralastic suspension belts
• Allows upholstery material, colour and stitching to be selected separately
• Provides a period-style bucket-seat profile for classic Porsche interiors
• Accommodates a standard 3-point seat-belt arrangement

Technical Details

• Kit includes the seat shell, Duralastic belts, side and backrest foam, cushion and headrest
• Fibreglass shell construction
• Untrimmed and ready for professional upholstery
• RSR-inspired bucket-seat design with up to 15 degrees of adjustment
• Specified for use with 3-point seat belts
• Mounting brackets, runners and upholstery must be confirmed separately

Symptoms of Fault

• Original seat foam has collapsed, cracked or lost its shape
• The cushion sags or no longer supports the occupant evenly
• The existing seat shell or frame is damaged, distorted or corroded
• Side and backrest support have deteriorated through age and use
• Worn upholstery exposes degraded foam or suspension components
• A complete supporting base is needed for a seat restoration

Why Replacement Matters

Renewing the shell, suspension and shaped foam together provides a consistent base for the finished upholstery. This avoids installing new coverings over weakened padding or tired supporting parts and gives the trimmer control over the final materials and detailing. Seat runners, brackets and belt anchorages are safety-critical, so suitable installation hardware should be selected and fitted by an experienced specialist.

FAQs

• Is upholstery supplied? No. The kit is untrimmed, allowing the covering material and finishing details to be chosen separately.
• What components are included? The kit contains the seat shell, Duralastic suspension belts, shaped foam sections, cushion and headrest.
• Is this suitable for standard seat belts? Yes. This version is configured for a 3-point seat-belt arrangement.
• Can the upholstery match an existing interior? A professional trimmer can select suitable materials, colours, stitching and piping to coordinate with the cabin.
• Are mounting parts included? Suitable model-specific brackets, runners and installation hardware should be confirmed separately.

• Porsche 964 (911) C4 1989-93
• Porsche 914 (1970-1976)

What This Product Does

A seat shell kit supplies the supporting structure, flexible suspension and shaped padding rather than a completely upholstered seat. Combining these underlying parts creates a prepared foundation that can be finished in leather, vinyl, fabric or another suitable automotive upholstery material.

The RSR-inspired profile reflects the lightweight competition-style seating associated with Carrera RS and RSR applications. Shaped cushion, side and backrest foam define the seat form, while Duralastic suspension belts provide a flexible platform beneath the occupant. The shell incorporates openings for a 5-point belt arrangement, with rosettes included to finish the belt cut-outs neatly.

Functions

• Provides the structural base for a complete upholstered bucket seat
• Uses Duralastic belts to create flexible support beneath the cushion
• Includes shaped foam for the cushion, sides and backrest
• Allows upholstery colour, material, piping and stitching to be selected separately
• Provides openings for use with a suitable 5-point belt installation
• Creates a classic RSR-style seating profile for restoration or competition-inspired interiors

Technical Details

• Kit includes seat shell, Duralastic suspension belts, side and backrest foam, seat cushion and headrest
• Fibreglass shell construction
• Supplied untrimmed for professional upholstery
• Seat-belt cut-out rosettes included
• RSR-inspired design with up to 15 degrees of adjustment
• Mounting brackets, runners and installation hardware must be selected separately

Symptoms of Fault

• Original seat foam has sagged, split or lost its intended shape
• The cushion no longer supports the occupant evenly
• Side or backrest padding has deteriorated through age and repeated use
• The existing shell or supporting structure is cracked, distorted or corroded
• Worn upholstery has exposed damaged foam or suspension parts
• A complete foundation is required for a custom seat restoration

Why Replacement Matters

Replacing the shell, suspension belts and shaped foam together gives the trimmer a consistent foundation for the finished covering. This avoids applying new upholstery over collapsed padding or weakened supporting components. Seat runners, brackets, belt anchorages and related fixings are safety-critical; compatibility and installation should therefore be checked by an experienced specialist.

FAQs

• Is the upholstery included? No. The kit is supplied untrimmed so the material, colour, stitching and piping can be selected for the intended interior.
• What is included in the kit? It contains the shell, Duralastic suspension belts, shaped side and backrest foam, seat cushion and headrest.
• Is it prepared for 5-point belts? Yes. This version has the appropriate belt openings and is supplied with cut-out rosettes.
• Can it be matched to an existing cabin? A professional trimmer can select suitable materials and finishing details to coordinate with the existing interior.
• Are runners and mounting brackets supplied? Suitable vehicle-specific runners, brackets and fixing hardware must be confirmed separately.

Inspired by Porsche's Monza Motorsport History

Monza was one of the fastest circuits in the world and played an important role in Porsche's early competition history.

Porsche took the lightweight 911 R to Monza for endurance record attempts, demonstrating the performance and durability of the car over sustained high-speed running.

The Monza seat takes its name from this famous circuit in recognition of the drivers and cars associated with this important period of Porsche motorsport.

Classic Early Porsche Bucket Seat Design

The Monza takes inspiration from the lightweight glass fibre bucket seats used in early Porsche racing and rally cars.

This type of seat offered considerably greater lateral support than conventional road seating while reducing unnecessary weight and giving the cockpit a purposeful competition appearance.

Porsche used this style of seat in its lightweight 911 R models, making the Monza particularly appropriate for period-inspired Porsche competition builds and restorations.

R & ST-Inspired Seating Profile

The Monza combines characteristics of the classic R and ST-style seats.

It provides easier entry and exit than the more restrictive R-style seat while offering taller side support than the ST-style design.

The upper section is also slightly wider, providing a useful balance between lateral support, driver space and accessibility.

This makes the Monza suitable for drivers who want the support of a classic competition seat without choosing an excessively restrictive bucket design.

Designed for a 5-Point Harness

This version of the Monza Seat Shell Kit is specifically equipped for use with a 5-point seatbelt harness.

The shell incorporates openings for the waist/lap belts and is supplied with rosettes to provide a neat, finished appearance around the harness openings.

This makes it particularly suited to classic rally cars, historic motorsport-inspired builds and performance-focused restomods where a multi-point harness system is being installed.

The harness must always be installed using appropriate mounting points and according to the harness manufacturer's instructions and any regulations applicable to the vehicle's intended use.

Lightweight Glass Fibre Shell

The Monza uses a lightweight glass fibre shell that provides a rigid and supportive foundation for the finished seat.

Its one-piece construction maintains a slim, clean profile while providing the lateral support expected from a classic competition seat.

The smooth rear surface is also an important part of the Monza's period appearance and can either be left exposed or incorporated into the chosen upholstery design.

Duralastic Seat Suspension

The redesigned Monza incorporates Duralastic suspension within the seat structure.

The Duralastic system provides controlled support beneath the occupant, helping create a firm but more comfortable seating position than a completely rigid seat cushion.

Combined with fire-resistant foam, it provides additional comfort during longer road, rally or historic motorsport events while retaining the supportive characteristics of the glass fibre shell.

Headrest Support Provision

Although the original Monza-style competition seats were not normally supplied with headrests, the redesigned Retro Trim shell incorporates provision for headrest supports.

These have been integrated without disrupting the smooth rear appearance of the seat shell, allowing the finished specification to be tailored to the individual vehicle.

Trip Device Attachment Provision

The Monza also incorporates provision for a trip device attachment.

This can be particularly useful in historic rally applications where navigation, distance or timing equipment needs to be positioned within the cockpit.

The feature adds versatility for cars being prepared for classic rally and touring events.

Original-Style Upholstery Options

Historically, this style of seat could be finished in two distinctive ways.

The shell could be completely upholstered in leatherette or leather, creating a more traditional finished appearance.

Alternatively, the seat could be trimmed in the style associated with R and ST competition seats, leaving the rear shell in a glossy black finish while extending the leatherette or leather around the seat bolsters.

Both approaches allow the finished Monza to be tailored to the character of the vehicle.

Have Your Seats Upholstered Locally

Purchasing the Monza as a seat shell kit gives you the freedom to choose your own upholstery materials and have the work completed by your preferred local trimmer or interior restoration specialist.

This allows the seats to be matched precisely to the rest of the vehicle interior.

Why Choose the Retro Trim Monza?

The Monza provides a particularly effective combination of classic Porsche motorsport appearance, lightweight construction and increased driver support.

Its profile bridges the gap between the more restrictive R-style seat and the lower-sided ST-style seat, while this version adds dedicated provision for a 5-point harness.

Retro Trim Monza 5-Point Harness Classic Porsche Seat Shell Kits

The Retro Trim Monza Seat Shell Kit provides a period-inspired seating solution for classic Porsche owners who want the appearance of an early competition bucket seat combined with dedicated provision for a 5-point harness.

Inspired by the lightweight seating associated with Porsche 911 R and early racing and rally cars, the Monza combines elements of the classic R and ST seat designs. Taller side bolsters provide useful lateral support, while its wider upper profile and easier entry make it less restrictive than some traditional racing buckets.

For historic rally, motorsport-inspired restoration and performance restomod projects, the lightweight glass fibre shell, Duralastic suspension and dedicated harness openings provide a strong combination of period appearance, support and practicality.
