SPL Parts Adjustable Rear Toe Links/Control Arms + Eccentric Lockout Plates (Delete) – Titanium/Aluminium, FK Spherical/Rose-Jointed – BMW F8X F80 F82 F83 F87 M2 M3 M4 Rear Alignment Toe Adjuster Kit (RTAEL F8X)

SPL Rear Toe Control Arms with Lockout Plates for BMW F8X M2 M3 M4

Take control of rear axle geometry on your BMW F8X with SPL Parts rear toe control arms and lockout plates. Built for precise alignment and repeatable setup, these rose-jointed links transform stability, traction and tyre wear on M2, M3 and M4 platforms used on fast road, track day, time attack and drift. Ideal for lowered cars where the factory adjusters run out of range or move under load.

The clever on-car adjustment system uses a 360 degree rotating clamp for quick, accurate changes, while the hybrid construction combines gun-drilled 2024 aluminium links with blue anodised titanium fasteners to cut unsprung mass and sharpen response. FK PTFE-lined spherical bearings deliver low-friction articulation and excellent durability without the vague feel and bushing squirm of the OE arms.

We use this setup on our own MJ Modifications development cars and customer builds, and feedback has been brilliant. Owners report rock-solid rear end stability, cleaner turn-in, better drive out of corners and noticeably improved tyre life once aligned correctly.
