Description
SPL Rear Toe Arms w/ Eccentric Lockouts - 06-13 BMW 1-Series/3-Series (1M/M3 ONLY) is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 06-13 BMW 1-Series/3-Series (1M/M3 ONLY). SPL Parts engineers performance suspension components in the USA with an emphasis on strength, low friction, precise adjustment, and alignment control for track and high-performance street cars.
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.
When combined with quality dampers and tires, precise suspension links help make chassis tuning changes easier to feel, measure, and reproduce.
