SPL Parts Toyota A90/Z4 Tie Rod Ends (Bumpsteer Adjustable)

Rubber should be saved for the tires. The factory tie rod ends on the Toyota GR Supra A90 and BMW Z4 G29 use soft rubber bushings that flex under load, which lets alignment and toe change right when you are asking the car to work the hardest. SPL Parts replaces those links with fully adjustable, spherical bearing components that keep the suspension honest and repeatable on both street and track.

Bumpsteer adjustable tie rods

These SPL tie rod ends let you correct tie rod geometry on lowered cars by relocating the outer joint. That means you can dial out excessive bumpsteer as you change ride height, keeping the steering calm and communicative over curbs and bumps.

We use SPL hardware across many of our own builds because it is easy to work with, holds settings and stands up to real track mileage. If you are dialing in the Toyota GR Supra A90 and BMW Z4 G29 for serious driving, these pieces are a key part of getting the alignment and feedback you want.
