SilverRocket Porsche LWB Seat Angle Adjuster (TC4 Titanium)
$335.00
SilverRocket Seat Angle Adjuster for Porsche Lightweight Buckets
This Adjuster Fits the Following Cars:
Porsche 981 GT4, 718 GT4 / GT4RS with LWB seat

Porsche 992 GT3 and GT3RS
The SilverRocket Porsche LWB Seat Angle Adjuster is an optimization 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 (known as "Lightweight Bucket" or "LWB" seats), aiming to create a comfortable sitting position similar to Porsche race cars. This makes for a more comfortable driving experience.
The SilverRocket Porsche LWB Seat Angle Adjuster can increase the backward tilt angle of the seat, giving you relief from the very upright original posture that's not suitable for extended-time driving. The original seat angle can cause discomfort in the neck due to the head being forced forward, especially when wearing a helmet and HANS device.
In addition, through SilverRocket's exclusive innovative design and precise production process, the Seat Angle Adjuster perfectly fits Porsche's original LWB seats so the seat height and front-back adjustment function is retained without damaging the seat rails.
Finally, to ensure maximum safety in a track environment, Silver Rocket uses ultra-high strength TC-4 titanium alloy, making the Seat Angle Adjuster stronger than the Porsche seat structure itself.
SilverRocket LWB Seat Angle Adjuster Benefits
Premium TC-4 Titanium: SilverRocket Porsche LWB Seat Angle Adjuster is made of a more expensive aerospace-grade TC-4 titanium alloy, which surpasses traditional aluminum in every aspect. Especially in high-pressure track driving, it provides over 10 times aluminum alloy's tensile strength and yield strength, giving you a safer driving experience and better durability.
Perfect Contouring: The SilverRocket Seat Adjuster is precisely CNC-machined to perfectly follow the contours of the mating surfaces of your LWB seats, creating the rigid structure that professional racers prefer.
Minimally Invasive Design: Unlike other products, this unique design does not mount to the seat slider hinges, ensuring that your slider remains undamaged and fully functional.
Sleek Appearance: The SilverRocket Seat Angle Adjuster is finished with electroplated black nickel, giving it a sleek and polished appearance that complements the interior aesthetics of your Porsche.
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 the SilverRocket Porsche LWB Seat Angle Adjuster, you create more space to accommodate your head or helmet, allowing for a much more natural and comfortable driving position.
