The GMG Thrust Arm Bushing Kit replaces the flexible factory rubber thrust arm bushings to significantly improve handling and responsiveness of the vehicle.
Stock rubber bushings compress under load, causing unwanted caster changes in both front and rear suspension under acceleration and deceleration. This allows the alignment to wander and makes the car less predictable. Our solid aluminum design eliminates compression to hold alignment settings precisely with minimal effect on road noise transmissions into the cabin. Compatible with all stock lower control arms, as well as adjustable GT3 and Porsche Motorsport Cup arms, each kit is sold as a set of 4 for both the front and rear arms.
