Seat Frame and Foam Kit with for Standard 3-Point Belts Monza. Porsche 911 / 914  ❭  SEATFRAMEMONZASTD

Monza was one of the fastest and most demanding circuits of its era and became an important part of Porsche competition history.

The Porsche 911 R demonstrated its performance and durability at the circuit during endurance record attempts, helping establish the lightweight 911 as a serious competition car.

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

Classic Early Porsche Bucket Seat Design

The Monza takes inspiration from some of the earliest glass fibre bucket seats used in racing and rally cars.

Porsche used this style of lightweight seat in its competition-focused 911 R, where reduced weight and increased driver support were important considerations.

The original Monza-style seat provided greater side support than conventional road seats while maintaining the simple, clean appearance characteristic of early Porsche competition interiors.

R & ST-Inspired Seating Profile

The Monza provides a useful compromise between the characteristics of the classic R and ST-style seats.

Entry and exit are easier than with the more heavily supported R-style seat, while the side bolsters are taller than those found on the ST-style design.

The upper section is also slightly wider, creating a seat that combines useful lateral support with improved accessibility and comfort.

This makes the Monza particularly suitable for classic Porsche owners who want a period motorsport appearance without choosing an overly restrictive competition-style seat.

Lightweight Glass Fibre Shell

The Monza uses a lightweight glass fibre shell to provide a rigid and supportive foundation.

The shell construction allows the seat to maintain a slim profile while providing the strength and lateral support required from a classic sports seat.

Its smooth rear surface also retains the distinctive appearance associated with early Porsche competition seating.

Designed for Standard 3-Point Seatbelts

This version of the Retro Trim Monza Seat Shell Kit is intended for vehicles retaining standard 3-point seatbelts.

Although the shell incorporates waist belt openings, this version does not include the rosettes used for the optional 5-point harness configuration.

This makes it particularly suitable for road-driven classic Porsche models where improved seating support and motorsport styling are desired while retaining the conventional seatbelt system.

Duralastic Seat Suspension

The redesigned Monza incorporates Duralastic suspension within the seat structure.

Rather than relying entirely on thick foam padding, the Duralastic system provides controlled support beneath the occupant, helping create a firm but comfortable seating position.

Combined with fire-resistant foam, this provides additional comfort for road use and longer journeys while retaining the supportive characteristics expected from a classic bucket seat.

Optional Headrest Support

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

These supports are integrated into the design without disrupting the smooth appearance of the back of the seat.

This allows the finished seat specification to be tailored more closely to the individual vehicle and owner's requirements.

Trip Device Attachment Provision

The redesigned Monza also incorporates provision for a trip device attachment.

This can be particularly useful in historic rally and touring applications where additional navigation or timing equipment may be required within easy reach of the driver or co-driver.

Original-Style Upholstery Options

The original seats were commonly finished in two distinctive styles.

They could be completely upholstered in leatherette or leather for a more conventional finished appearance, or trimmed in the style associated with the R and ST seats, leaving the rear shell exposed in a glossy black finish with the upholstery extending over the bolsters.

These different approaches allow the Monza to suit anything from a classic road restoration to a more competition-inspired Porsche interior.

Have Your Seats Upholstered Locally

Purchasing the Monza as a seat shell kit allows you to have the upholstery completed by your preferred local trimmer or interior restoration specialist.

This gives you control over the materials, colours and finished appearance while making it easier to coordinate the seats with the rest of the vehicle interior.

Why Choose the Retro Trim Monza?

The Monza is particularly well suited to classic Porsche owners looking for a period-inspired bucket seat that provides useful lateral support without making entry and exit unnecessarily difficult.

Its combination of R and ST-style characteristics creates a versatile seat for road, restoration, historic rally and restomod applications.
