Product Description

The SPL EL G29 Rear Toe & Camber Eccentric Lockout Kit is engineered for owners of the BMW Z4 (G29) and Toyota GR Supra (A90) who want their rear suspension geometry to remain rock-solid under aggressive driving conditions. By replacing the factory rear eccentric bolts with lock-out plates and high-grade hardware, this kit prevents unwanted alignment shifts that can occur during high G-cornering, track use, drifting or lowered setups. What you gain is consistent toe and camber behaviour, improved tyre wear characteristics, and confident, repeatable handling lap after lap.

Installation is straightforward for a performance-capable technician: remove the factory eccentrics at the rear toe and camber arms, install the supplied lock-out plates and secure with the provided grade 10.9 bolts and lock nuts. Because the adjustment function is eliminated, you must have adjustable rear arms (or already set geometry) to tune toe and camber before installation. After fitting, a full 4-wheel alignment is strongly recommended. Coverage is confirmed through 2024 for both supported models; fitment for 2025 is **unconfirmed** at time of listing.
