SPL Parts Rear Traction Links - 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29)

SPL Parts Rear Traction Links - 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) 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). 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.

This adjustable longitudinal suspension link replaces a compliance-heavy factory connection and provides a more direct way to control wheel motion under acceleration and braking. Depending on the chassis geometry, link-length changes can also be used to influence anti-squat characteristics and wheelbase position. Reducing deflection helps the rear suspension react more consistently to throttle inputs, improving mechanical grip, transient response, and confidence when loading the tire on corner exit.

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. Adjustment is most valuable on lowered or competition cars where the factory geometry has moved away from its intended operating window.

When combined with quality dampers and tires, precise suspension links help make chassis tuning changes easier to feel, measure, and reproduce.
