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 using a 5-point harness and features the required seatbelt cut-outs with finishing rosettes.

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 a 5-Point Harness

This version incorporates dedicated openings for routing the waist/lap belts of a 5-point harness.

Seatbelt cut-out rosettes are included, providing a neat finished edge around the harness openings while maintaining the classic appearance of the seat.

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
  • 5-point harness cut-out rosettes       

Retro Trim TransAm 5-Point Harness Classic Racing Seat Frame Kits

The Retro Trim TransAm Seat Frame Kit is designed for classic car owners looking for the appearance and support of a traditional Trans-Am competition seat combined with provision for a modern 5-point harness.

Its welded lightweight steel frame, high side bolsters, lowered seating position and Duralastic suspension make it particularly suitable for classic Porsche, American muscle cars, European sports cars, historic rally builds and competition-inspired restomods.

Dedicated harness cut-outs and supplied rosettes provide the necessary belt routing through the seat, while local upholstery allows the finished seat to be tailored to the style and materials of the vehicle.

About Seat parts

Porsche Seat Parts | Comfort, Support & Precision Engineering for Every Drive

Seats are among the most important components in your Porsche’s interior — balancing comfort, safety, and driving control. Over time, mechanical seat components such as runners, motors, adjusters, or mounting brackets can wear down, affecting comfort and performance. Proper maintenance and replacement of seat parts ensure your Porsche retains its driving precision and luxury appeal.

At Design911, we supply high-quality seat parts and accessories engineered to meet or exceed original performance standards. Our range includes seat adjustment mechanisms, runners, seat cushions, backrest components, and mounting hardware — all designed for precision fitment and long-lasting reliability.

Whether you’re restoring a classic Porsche 911, upgrading a Cayman, or repairing a Boxster, Design911 offers the seat parts you need to restore comfort, safety, and interior refinement.

What Do Seat Parts Do?

Seat components work together to provide proper ergonomics, support, and functionality inside your Porsche.

Core Functions:

  • Support the driver and passengers with structural integrity and comfort.
  • Enable adjustment for optimal seating position and driving visibility.
  • Secure seats to the vehicle’s chassis for safety and stability.
  • Integrate heating, lumbar support, and electrical adjustments.
  • Contribute to interior aesthetics and occupant comfort.

Every Porsche seat is engineered for precision; maintaining its components ensures consistent comfort and safe performance.

Why Do Seat Components Wear or Fail?

Even with premium materials, seat mechanisms and fittings can deteriorate over time from regular use, vibration, and environmental exposure.

Common Causes of Wear or Failure Include:

  • Mechanical fatigue or broken adjuster cables.
  • Corrosion or seized components in seat rails or runners.
  • Electrical faults in seat motors or heating systems.
  • Damaged foam cushions or collapsed seat bolsters.
  • Worn brackets or loose mounting hardware.

When seat components fail, you may notice limited movement, uneven support, or increased cabin noise — all of which impact comfort, safety, and driving enjoyment.
