Product Details

SPL Parts Adjustable Front Caster Rods for the 2019+ BMW Z4 (G29). The SPL adjustable caster rods (TR G29) for the Toyota Supra (A90 / A91) and BMW Z4 (G29) provide adjustable caster and anti-dive to improve mechanical cornering grip and stability under aggressive braking.

The billet aluminum arms use PTFE-lined, F1-fit FK USA spherical bushings to eliminate bushing deflection and bind, which are the primary causes of vague steering and braking feedback. The adjustable caster arms, aka tension rods, allow for a deeper customization of the suspension geometry to better suit your driving preferences and adapt to changes in tracks, aero loading, tires, and more.

Sold as a complete kit for one car. Made in the USA.
