Product Overview

Stop rear-toe misalignment with the XC3 Engineering Rear Toe Lockout Shims, a simple and robust solution for owners upgrading to adjustable rear toe arms on the BMW M340i M440i (F3X F4X platform).

The OEM rear suspension relies on eccentric adjustment bolts which can shift under load, leading to unwanted toe change and inconsistent handling. XC3 Toe Lockout Shims eliminate this weak point by replacing the eccentric adjustment with a fixed, mechanically locked mounting solution.
