BMW M2 / M3 / M4 F8X & G8X Rear Toe Lockout Shims – Alignment Lock Kit | XC3 Engineering
Product Overview
Improve the rear suspension geometry of your BMW M2, M3 or M4 (F8X 2016–2021 / G8X 2020–2025) with XC3 Engineering Rear Toe Lockout Shims.
The factory toe adjustment relies on an eccentric bolt that can slip under heavy load, hard cornering, track use or aggressive alignment settings - causing unpredictable handling and inconsistent geometry.
Our lockout shims replace the OEM eccentric system and provide a fixed, positive-location mounting point, ensuring your chosen toe setting stays locked in place at all times. A must have upgrade for anyone running our Billet Adjustable Toe arms or any aftermarket adjustable Toe arms.
Designed and machined in the UK for precision and durability.
