Replacing the flexible rubber thrust arm bushing with this solid design will significantly improve the handling and response from your 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. 

The adjustable version (shown) allows for adjustment of additional caster as well.

Unlike the other designs on the market, the 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 one control arm.  Four kits (2 front & 2 rear) required per car.
