SPL Parts Toe Eccentric Lockout Kit

2020–2023 Toyota GR Supra (A90), 2019+ BMW Z4 (G29), 2018+ BMW G20, G21, G22, G23, G24, 2021+ BMW G42

SPL ELT G29

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.

Key Features:

Built to provide zero-slip rear alignment retention, the SPL Parts Toe Eccentric Lockout Kit offers the following benefits:

  • Eliminates stock eccentric bolts prone to slipping under high lateral forces
  • Maintains consistent rear toe settings for improved handling precision
  • Compatible with adjustable control arms for continued alignment adjustability
  • CNC machined from high-strength 6061-T6 aluminum for durability and lightweight performance
  • Includes zinc-plated grade 10.9 bolts and lock nuts to ensure secure, corrosion-resistant fastening
  • Complete kit includes hardware for both camber and toe arms
  • Designed specifically for Toyota GR Supra A90 (2020–2023), BMW Z4 G29 (2019+), and select BMW chassis (G20, G21, G22, G23, G24, G42)
  • 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.

What's Included:

  • CNC machined 6061-T6 aluminum lockout plates for toe and camber arms
  • Zinc-plated grade 10.9 bolts and lock nuts
  • Washers for proper fitment and secure fastening
  • Complete hardware set for one vehicle
  • Installation instructions

Ideal For:

This lockout kit is ideal for performance enthusiasts, track day drivers, and anyone seeking to maintain precise rear alignment settings on their Toyota GR Supra A90 or BMW Z4 G29. It is especially beneficial for vehicles equipped with adjustable rear control arms where consistent toe settings are critical for handling performance and tire wear reduction. If you experience rear alignment changes during aggressive cornering or track use, this kit provides a reliable solution to keep your suspension geometry locked in place.
