$290.00

Tarett Engineering’s solid thrust arm bushing upgrade replaces the factory rubber bushing to significantly improve handling precision and suspension response across Porsche 996, 997, 991, 992, Boxster, and Cayman models.

By eliminating unwanted bushing deflection, this design reduces caster changes under acceleration and braking, resulting in more consistent geometry and improved driver feedback—while maintaining minimal increase in cabin noise. An adjustable version is also available, allowing for additional caster tuning.

Unlike other designs, this system incorporates extra clamping hardware to prevent slipping under heavy loads, ensuring reliable performance in demanding conditions. It is compatible with stock control arms as well as GT3 and Porsche Motorsport Cup-style arms.

Ideal for both spirited street driving and track use, each kit services one axle, with two kits required per vehicle. (Note: Not applicable for certain GT models already equipped with solid bushings.)
