The stock eccentric bolts provided by BMW for small toe adjustments tend to slip under high cornering loads, causing changes to the rear alignment. Our SPL Parts Eccentric Lockout (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 toe and camber after eliminating the stock eccentric bolts (RTA F3x and RUA F3x). Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with zinc plated grade 10.9 bolts and lock nuts for absolutely zero-slip. This kit includes washers and bolts for toe arms and camber arms. Sold as a complete kit for one car.Made in the USA. Applications: 2010 &ndash
