SPL Parts Titanium Rear Toe Links with Eccentric Lockout Kit for Toyota GR Supra A90 MK5 (2020+) and BMW Z4 G29 (2019+) - Adjustable Rear Toe Control Arms / Alignment Lockout - SPL RTAEL G29

SPL Titanium-Series Rear Track Rods with Cam Bolt Lockout for Toyota Supra MK5 A90 and BMW Z4 G29

Unlock laser-accurate rear geometry and confidence-inspiring stability with SPL Titanium-Series rear track rods and cam bolt lockout plates for the Toyota GR Supra A90 MK5 and BMW Z4 G29. These motorsport-grade rear toe adjusters replace the flimsy factory arms and remove the imprecise OEM cam adjustment, delivering repeatable alignment, sharper rear-end response and improved tyre life for fast road, track day and lowered setups.

We run these on customer cars and the feedback is consistently excellent. Expect crisp turn-in, predictable traction out of bends and a planted rear axle at speed. If you want robust rear toe control that stays put under hard braking and cornering, this is the upgrade Supra MK5 and Z4 G29 owners choose.
