Overview:

The SPL Parts Toe Eccentric Lockout Kit is engineered to eliminate the common issue of rear alignment drift caused by slipping stock eccentric bolts on Toyota GR Supra A90 and BMW Z4 G29 models, as well as select BMW chassis from 2018 onward. Designed for enthusiasts and racers who demand precise and consistent rear toe settings, this kit replaces the factory eccentric bolts with robust lockout plates to maintain your alignment under high cornering loads. If your vehicle is equipped with adjustable control arms, this kit ensures your toe adjustments remain rock solid, enhancing handling stability and confidence on the road or track.

• Manufactured, engineered, and assembled in the USA for quality assurance

Construction & Design:

The lockout plates are precision CNC machined from 6061-T6 aluminum, a material known for its excellent strength-to-weight ratio and resistance to deformation. This ensures the plates maintain their shape and function even under extreme cornering forces. The kit’s hardware features zinc-plated grade 10.9 bolts and lock nuts, providing superior clamping force and corrosion resistance to withstand harsh driving conditions. The design replaces the factory eccentric bolts with a solid lockout solution that prevents any unwanted movement, preserving your carefully set rear alignment angles.

Installation & Fitment:

Installation of the SPL Parts Toe Eccentric Lockout Kit requires removal of the stock eccentric bolts and replacement with the supplied lockout plates and hardware. Because the kit eliminates the factory method of toe adjustment, adjustable control arms are necessary to fine-tune rear toe settings after installation. The kit is a direct fit for the following vehicles: 2020–2023 Toyota GR Supra A90, 2019+ BMW Z4 G29, 2018+ BMW G20, G21, G22, G23, G24, and 2021+ BMW G42 chassis. Professional installation is recommended to ensure proper torque and alignment accuracy.
