Product Description

The SPL Parts SPL EL F8X Eccentric Lockout Kit solves a common headache on F8X and G8X M2/M3/M4 BMWs: the stock eccentric bolts used for small toe adjustments tend to slip under hard cornering, letting your rear alignment drift over time. This kit locks that alignment in place using CNC-machined 6061-T6 aluminum plates and zinc-plated grade 10.9 hardware for a genuinely zero-slip setup.

Because it locks out the stock adjustment range entirely, you'll need adjustable control arms (like SPL's own RTA and RUA F3X arms) already installed to dial in toe and camber before locking things down. Made in the USA and sold as a complete kit for one car, it's a smart pairing for anyone running SPL's adjustable rear arms who wants their alignment to actually stay put on track.
