BMW 4 Series Eccentric Lockout Kit - SPL Parts. Locks in precise rear alignment on F3X 4 Series (2012+) by replacing factory eccentrics that can shift under load.

By removing the OEM eccentric bolts, this kit helps keep toe and camber settings consistent during aggressive driving. CNC machined 6061-T6 aluminum lockout plates pair with zinc plated grade 10.9 hardware and lock nuts to create a rigid, no-slip interface. The kit includes washers and bolts for both toe and camber locations and is sold as a complete set for one car. Note: adjustable toe and camber arms are required to make alignment changes after installation.
