SPL Parts 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) Tie Rod Ends (Bumpsteer Adjustable)

When you're working on a performance vehicle like a Toyota GR Supra (A90) or a BMW Z4 (G29), you get a pair of SPL Parts adjustable tie rod ends. These are designed to help you fine-tune your suspension geometry, especially if you've lowered the car or changed other suspension components. They work by allowing you to relocate the tie rod end's pivot point. This is important because it helps correct bump steer, which is when your steering angle changes unintentionally as the suspension moves up and down. Fixing bump steer can lead to more predictable handling and quicker lap times on a track.

These tie rod ends are well-built in the USA using quality materials. They feature custom CNC machined 6061-T6 billet aluminum turnbuckles that allow for maximum articulation, meaning they can move freely with the suspension without binding. This is crucial for preventing the inner tie rods from breaking or bending, especially when the car is significantly lowered or used in racing conditions. They also use low-friction Teflon-lined FK Heim joints for smooth operation and include stainless steel bump steer spacers for precise adjustment. The socket head cap screws used are ASTM A574, known for their high tensile strength, ensuring a robust connection.

This set includes the adjustable tie rod ends, along with stainless steel bump steer spacers for fine-tuning. They are designed to fit a range of vehicles including the 2020+ Toyota GR Supra (A90), 2019+ BMW Z4 (G29), and various G20/G21/G22/G23/G24 chassis BMWs with an inline 6 engine or AWD, as well as the 2021+ G42 chassis with the same engine/drivetrain configurations.
