Description
SPL Rear Toe Links w/ Eccentric Lockouts - 15-20 BMW M2/M3/M4 (F8X) is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 15-20 BMW M2/M3/M4 (F8X). 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 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.
After installation, recheck fastener torque and alignment after the initial heat cycles or track use so the setup remains repeatable.
