Replacing the flexible rubber thrust arm bushing with this solid design will significantly improve the handling and response from your 991/996/997, Boxster or Cayman suspension.
Eliminates unwanted caster changes in both front and rear suspension under acceleration and deceleration, with minimal effect on road noise transmissions into the cabin.
Allows for adjustment/correcting of caster as well, when adding LCA shims.
Unlike the other designs on the market, our adjustable kit uses two additional bolts to provide the extra clamping force needed to prevent slipping under heavy loading.
Compatible with all stock lower control arms, as well as adjustable GT3 and Porsche Motorsport Cup arms.
A great improvement for street cars and a must for anyone taking their car to the track.
Each kit is for two control arms. Two kits (2 front & 2 rear) required per car.
* Also for all non GT fronts that have already been converted to two-piece GT arms.
* Not for GT4 rear
note: Tighten M8 locking screws to 19 ft-lbs.
