Description
SPL Parts 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) Rear Swaybar Endlinks is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) Rear. SPL Parts focuses on competition-grade suspension and alignment hardware, combining in-house development with U.S.-sourced materials and precision manufacturing for demanding street and track applications.
These adjustable sway-bar end links create a more direct connection between the anti-roll bar and suspension while allowing link length to be set for the vehicle's actual ride height. Correct end-link length helps remove unwanted anti-roll-bar preload at static ride height, so left-to-right response is more symmetrical and bar rate is delivered more consistently during cornering.
Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. Lower-compliance joints also sharpen transient response, making this a useful supporting modification for coilovers, adjustable bars, corner balancing, and track alignment work.
This type of hardware is most effective as part of a complete alignment strategy, where camber, caster, toe, ride height, and tire behavior are evaluated together.
