SilverRocket PORSCHE LWB SEAT ANGLE ADJUSTER - TC4 TITANIUM [PORSCHE 981 / 718 / GT4 / RS, 991 GT3 / RS]

Silver Rocket Seat Angle Adjuster for Porsche GT3 (991.2)

Easy to install, and get comfortable position to drive. Good adjuster quality and stiffness for safety. I'll recommend this to other users. A few point for installation. 1) Carbon seat backrest will touch to roll cage after adjuster installation. Be careful to avoid backrest carbon damage when you slide back seat to the end. 2) Are we sure we can remove (-) battery terminal for installation without any error message? Japanese dealer strongly recommended to avoid any battery terminal removal to avoid error message. So I removed fuse for both seat power supply. And I don't have any error after installation.

Messes with seat rising and lowering adjustability

Product interferes with seat rising and lowering adjusting ability, would not recommend. Not a well thought out design.

Hard to fit

The pieces are just the tiniest bit too wide to fit within the seat rails. You can make them fit using a C-clamp, but then it becomes difficult to make the threaded hole line up perfectly. If it was just 1mm thinner, this would be a far better product. Once installed, however, it seems to work well and the angle feels natural and comfortable with a helmet on.
