SPL Parts 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) Front Caster Rod Bushings (Non-Adj)

SPL Parts is known for making well-built suspension components that help drivers get the most out of their cars. If you're looking to improve the feel and response from your 2019-2024 BMW Z4's front end, these non-adjustable caster rod bushings are a solid option. They replace the factory rubber bushings, which can flex and deflect under load, with low-friction spherical bearings. This helps keep your suspension geometry stable, especially during hard braking and cornering, leading to more predictable handling and better feedback through the steering wheel.

These bushings use large, 1-inch FK racing bearings that have self-lubricating Teflon liners. This design helps reduce friction and eliminates unwanted bushing deflection, maintaining precise suspension alignment when you need it most. The bearing housings are made from 6061-T6 aluminum and feature an outer knurl for a secure fit. They are proudly made in the USA, ensuring solid construction and attention to detail.

By eliminating the flex found in stock rubber bushings, you'll notice an improved connection to the road and more confidence when pushing your Z4. This kit is sold as a pair and is designed for a direct fit on your specific vehicle.
