Race-bred rear link kit for Mk5 Supra A90 and BMW Z4 G29
Transform rear end grip, launch consistency and stability with this SPL Parts rear traction link kit. Designed for hard road use, track days, drift and drag, these adjustable rear bars let you dial in rear geometry for sharper throttle response, reduced wheel hop and confidence under braking. Expect a calmer, more planted back end on bumpy roads and curbs, and stronger traction on corner exit.
We fit these on our own builds and customer cars and the feedback has been brilliant. Faster launches, less axle tramp and a more precise, connected feel. A proper handling upgrade for anyone chasing reliable performance from a Mk5 Supra A90 or G29 Z4.
