Fall-Line Motorsports Adjustable Rear Upper Control Arm Set - BMW F80 M3 / F82 M4 / F87 M2

F8X M cars are quick to step out when the rear rubber lets the axle shift under load. The Fall-Line Motorsports Adjustable Rear Upper Control Arm Set replaces the factory arms (BMW 33-32-2-284-777) with adjustable arms on spherical bearings, so rear geometry stays consistent corner after corner.

More confidence on corner exit, with only a marginal NVH increase.

FK Spherical Bearings and Clamp-Style Adjusters

Long-life FK spherical bearings outlast the OEM rubber. A motorsport clamp-style fastener makes alignment changes fast and keeps them set. Made in the USA.
