The stock Eccentric Bolts provided on your 2008-2013 BMW M3 (E90/E92/E93) for small camber/toe adjustments tend to slip under high cornering loads, causing changes to the rear alignment. Our SPL Parts Eccentric Lockout Arm (EL) kit eliminate the stock Eccentric Bolts to keep your rear alignment where you set it. You must have adjustable control arms in order to adjust camber/toe after eliminating the stock Eccentric Bolts. Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with CAD plated grade 10.9 hardware for absolutely zero-slip. One kit includes washers and bolts for both camber arms. Sold as complete kit for one car. Made in the USA.
