SPL Bumpsteer Adjustable Tie Rod Ends - Toyota Supra GR A90 GR / BMW Z4 (G29)

SPL Parts Bumpsteer Adjustable Tie Rod Ends (TRE) are engineered to significantly improve steering precision and front-end stability by correcting bump steer on lowered Toyota Supra GR A90 and BMW Z4 G29 models. Factory tie rod geometry is often compromised when ride height is altered, leading to unpredictable handling and unwanted toe changes under suspension compression. Our adjustable tie rod ends restore proper geometry, enhancing grip, turn-in response, and overall driving confidence—whether on the street or track.

Precision Engineering & High-Quality Materials

Our tie rod ends feature CNC-machined 2024-T6 aluminum bodies for strength and lightweight performance, while gun-drilled 4140 chromoly steel shanks ensure maximum durability. The adjustability comes from our 6061-T6 aluminum locking collars with our signature 360-degree Rotating Clamp system, making fine-tuning quick and hassle-free without the need for jam nuts.

Race-Grade Spherical Bearings

We use high-strength FK Bearings spherical rod ends with PTFE liners, providing:
✔ Elimination of bushing deflection for razor-sharp steering feel
✔ Low-friction, smooth articulation for maximum precision
✔ Extended durability in high-load conditions
