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.

The Porsche LWB Seat Angle Adjuster is an optimisation accessory designed by the SilverRocket racing team based on years of experience in endurance racing with Porsche race cars. It is specifically designed for Porsche's original carbon fiber bucket seats, aiming to create a comfortable sitting posture similar to Porsche race cars, allowing for a more comfortable driving experience.

Porsche LWB Seat Angle Adjuster can increase the backward tilt angle of the seat, solving the problem of the original upright posture that is not suitable for long-time driving, especially when the original seat angle causes discomfort in the neck due to the head being forced forward when wearing a helmet.

In addition, through SR's exclusive innovative design and precise production process that perfectly fits Porsche's original LWB seats, the seat height and front-back adjustment function can be retained while changing the seat angle, without damaging the seat rails.

Finally, to ensure the safety of our product in a track environment, we exclusively use ultra-high-strength TC-4 titanium alloy, which provides better reliability and safety beyond the original strength of Porsche in a track environment.

Highlights:

High Quality TC-4 Titinium: 

Porsche LWB Seat Angle Adjuster is made of a more expensive aerospace-grade TC-4 titanium alloy, which surpasses the traditional aluminum option in every aspect. Especially in high-pressure track driving, it provides over 10 times the aluminum alloy's tensile strength and yield strength, bringing you a safer driving experience and better durability.

Perfect Contouring:  
Our seat adjuster is precisely CNC engineered to perfectly contour the shape of the mating surfaces of your LWB seats, creating a rigid structure that professional racers prefer.

Minimally Invasive Design: 
Unlike other products, our unique design does not mount to the seat slider hinges, ensuring that your slider remains undamaged and fully functional.

Sleek Appearance:  
The seat adjuster is finished with electroplated black nickel, giving it a sleek and polished appearance that complements the interior aesthetics of your Porsche 992 GT3 RS.

Function:
By increasing the incline of the driver's seat, you can achieve a better seating posture for both high-performance driving and long-distance comfort. This is particularly crucial when wearing a helmet on the track. The original upright seating position can force your head to bend forward with extensive discomfort and loss in performance. With our seat adjuster, you can create more space to accommodate the helmet, allowing for a natural and comfortable driving position.
