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

SPL Tie Rod Ends for the Toyota Supra (A90) and BMW Z4 (G29) allows for bumpsteer adjustment by allowing the tie rod end pivot to be relocated with the use of spacers. On lowered cars, this results in less dynamic toe change (aka bumpsteer) as the suspension compresses (bump) during cornering and over rough roads, resulting in more predictable handling, less tire shoulder wear, and better stability over rough roads and track curbing. For Supras and Z4s that are lowered significantly, the ability to move the tie rod end pivot point allows you to avoid binding, and subsequent failure / bending, of the OEM tie rods.
