The SPL Parts E9M Eccentric Lockout Kit replaces the factory BMW eccentric bolts used for rear camber and toe adjustments. Under high cornering loads, the stock hardware can slip and allow the rear alignment to change. This lockout solution secures the alignment settings you establish, helping maintain consistent handling and predictable performance during spirited driving, track use, and competition applications.
The lockout plates are CNC machined from 6061-T6 aluminum and supplied with cadmium-plated Grade 10.9 hardware for a secure, zero-slip installation. Because the factory eccentric adjustment is eliminated, adjustable control arms are required to set rear camber and toe. Verify that your vehicle is equipped with compatible adjustable arms before installation. Each kit includes the required washers and bolts for both rear camber arms and is supplied as a complete kit for one vehicle.
Designed for BMW M chassis applications, the SPL Parts E9M kit fits select 2006-2011 E9X M models and is also compatible with listed BMW M3 and 1 Series M applications. Confirm vehicle fitment and control-arm compatibility before ordering. The kit is proudly engineered, assembled, and made in the USA, providing a durable alignment-retention solution for performance-focused BMW builds.
