What is the main benefit of using an eccentric lockout kit?

This kit replaces BMW's stock eccentric bolts, which can slip under high cornering loads. By eliminating these, the kit ensures your rear alignment settings for toe and camber remain stable and precisely where you set them.

What else do I need to install this kit?

You must have adjustable control arms (like the RTA F3x and RUA F3x) already installed on your vehicle. This kit eliminates the factory adjustment points, so you'll need those aftermarket arms to adjust toe and camber after installation.

What materials are used in this kit?

The lockout plates are CNC machined from 6061-T6 aluminum. The included bolts and lock nuts are zinc-plated grade 10.9 hardware, designed for a zero-slip connection.
