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.

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

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 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

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 914 (1970-1976)

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.
