Priced and sold individually. Each kit is for one control arm, meaning you will need 2x front or 2x rear depending on your application and installation. 

The Tarett solid thrust arm bushing kit is designed to eliminate unwanted caster changes under acceleration or deceleration, with minimal changes in noise, vibration or harshness or road noise from the driver's seat. Unwanted changes in caster will effect all other alignment settings including camber plus vehicle stability and feel.

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.

The adjustable version (shown) also allows for adjustment (increase) of additional caster. Increasing caster will effect dynamic camber and increase stability due to an effective lengthening of the wheel base. Increasing the caster angle will also increase self-centering effect and steering effort. A great improvement on street cars, and especially those taking their cars to the track. 

Unlike other designs on the market, the Tarett 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.
