SPL Parts Bumpsteer Adjustable Tie Rod Ends - Toyota GR Supra (A90/A91) & BMW Z4 (G29)

OVERVIEW

SPL Parts Front Tie Rod Ends (TRE) allow the tie rod end pivot to be relocated with the use of spacers. On lowered cars this results in less dynamic toe change — bumpsteer — as the suspension compresses during cornering and over rough roads, producing more predictable handling, less tire shoulder wear, and better stability over rough surfaces and track curbing.

For Supras and Z4s that are lowered significantly, the ability to move the tie rod end pivot point also lets you avoid binding and the subsequent failure or bending of the OEM tie rods.

SPECS

• Relocates the tie rod end pivot using included spacers
• Corrects bumpsteer resulting from lowering, modified caster, or lower arm geometry
• Prevents OEM tie rod binding, bending and failure on significantly lowered cars
• Reduces dynamic toe change for more predictable handling and less tire shoulder wear
• Not a significant contributor to NVH — improves the driving experience on uncorrected cars
• Sold as a pair, one pair per vehicle; made in the USA
