Handmade around a welded lightweight steel tube frame, the TransAm combines high lateral support, a low seating position and Duralastic suspension to create a classic competition-style seat suitable for restoration, restomod and historic motorsport-inspired cars.
This version is designed for cars retaining standard 3-point seatbelts.
Inspired by Classic Trans-Am Racing
The Trans-Am race series brought together some of the most recognisable performance cars of the period, including Mustang, Cougar, Corvette, Camaro, Porsche, Challenger, Datsun, Charger, AMC, Triumph and Jaguar.
Many competition cars used lightweight fibreglass, alloy or specially fabricated racing seats to provide drivers with greater support during demanding race conditions.
The Retro Trim TransAm recreates this purposeful appearance while providing a seat suitable for today's classic car enthusiast.
High Lateral Support
The TransAm features raised side bolsters extending towards the front of the seat to provide increased lateral support.
This helps hold the driver more securely during enthusiastic driving while maintaining the distinctive appearance of a traditional 1960s and 1970s competition seat.
Designed for Standard 3-Point Seatbelts
This version is intended for vehicles retaining their standard 3-point seatbelt system.
It provides the increased support and classic competition appearance of the TransAm design without requiring a conversion to a multi-point harness.
Lightweight Steel Tube Frame
The seat is handmade using a welded lightweight steel tube frame, providing a strong foundation while retaining the lightweight philosophy of traditional competition seating.
Fire-resistant foam and Duralastic suspension belts provide a firm but comfortable seating position, helping make the TransAm suitable for longer road journeys as well as historic motorsport-inspired applications.
Low Seating Position
The TransAm seat itself is non-adjustable and is designed to position the driver as low as practical within the vehicle.
Final seat height and angle are determined during installation, allowing the mounting arrangement to be selected to suit the driver and vehicle.
An optional tilting bracket is available where improved access to rear seating is required.
Have Your Seats Upholstered Locally
Supplying the TransAm as a seat frame kit allows the upholstery to be completed by your preferred local trimmer or interior restoration specialist.
This gives you the freedom to choose leather, vinyl, fabric or period-style materials and match the seats to an existing classic interior or create a completely bespoke specification.
Kit Includes
- Seat frame
- Duralastic suspension belts
- Side foam
- Back foam
- Seat cushion
- Headrest
Retro Trim TransAm 3-Point Seatbelt Classic Racing Seat Frame Kits
The Retro Trim TransAm Seat Frame Kit is designed for classic car owners looking to combine period Trans-Am racing style with improved driver support and standard 3-point seatbelt compatibility.
Its welded lightweight steel tube frame, raised side support, Duralastic suspension and low seating position make it particularly suited to classic Porsche, American muscle, European sports car and historic racing-inspired projects.
The unfinished kit can be upholstered locally in materials chosen to complement a period restoration or create an individual restomod interior.
