Description
SPL Rear Toe Links w/ Eccentric Lockouts - 20+ Toyota GR Supra / 19+ BMW Z4 is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 20+ Toyota GR Supra / 19+ BMW Z4. SPL Parts is a U.S.-based performance-suspension specialist that develops motorsport-oriented chassis hardware for precise alignment, low compliance, and repeatable setup changes.
These adjustable rear toe links replace compliant factory locating hardware with a more rigid, serviceable link that gives the alignment technician direct control over static toe. The included eccentric lockout strategy also removes a common source of alignment migration under high lateral load. More precise rear toe control improves straight-line stability, turn-in consistency, and rear-axle predictability while helping maintain the intended alignment as cornering, braking, and acceleration loads build.
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. They are especially useful on lowered cars where factory eccentric range may be insufficient or where repeatable track alignment settings are a priority.
For best results, set the final geometry around the vehicle's tire, ride height, and intended street/track use rather than relying on generic factory targets.
