The rear toe on the Supra and Z4 is set with eccentric bolts from the factory. Under hard cornering those eccentrics can slip, and the rear alignment moves with them. SPL's lockout kit replaces the eccentric bolts so the setting stays where your alignment shop put it.
What you get
- Lockout plates CNC machined from 6061-T6 aluminum.
- Zinc-plated grade 10.9 bolts and lock nuts to replace the factory eccentric hardware.
- A complete kit for one car, made in the USA.
Good to know
- Once the eccentric bolts are gone, toe can only be adjusted with adjustable control arms, so plan to run them with this kit.
