The incredible Lightweight Bucket Seats from Porsche adorn many vehicles from the 918 to the GT3, GT2, GT4, T and many other models if so equipped.
We created this adjustable lumbar support for our vehicles out of necessity. Not only for the driver but the passenger who agreed to that 6 hour journey as our co-pilot. Typically these are quite comfortable seats but on longer journeys, a little lumbar support goes a long way to comfort the back of you and your co-pilot.
These install in a minute for each side, adjustable for height (lower back, small of back, etc)
The air bladder is adjustable via a simple and lightweight ball pump and once the desired support is obtained, the ball pump can be removed and the hose and check valve tucked into the seat for an invisible install. Or just keep the ball for adjustment at anytime.

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.

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