SPL Adjustable Rear Upper Arms

BMW F80 M3 | F82/F83 M4 | F87 M2

Achieve precise rear camber adjustment and improve suspension performance with these SPL Adjustable Rear Upper Arms. Designed for BMW F8X vehicles, this complete kit replaces the factory rear wishbone and guide links to provide a wide adjustment range for both street and track alignment setups.

Lowered BMWs often develop excessive negative rear camber, which can cause premature inner-edge tire wear and reduce traction during acceleration. These adjustable arms allow rear camber to be properly corrected while eliminating the deflection found in the factory rubber bushings.

The arms feature gun-drilled 2024 aluminum links for reduced weight, a durable black anodized finish, and SPL’s rotating clamp design for fast and precise adjustment. Teflon-lined FK spherical rod ends provide smooth articulation, reduced friction, and consistent suspension geometry under load.

Sold as a complete kit for one vehicle with four total arms.
