Fall-Line Motorsports Rear Lower Control Arm Cup Subframe Bearing Set for BMW G8X, F8X, F87, E9X, E82 M Cars
Made in the USA
Upgrade your BMW M car suspension with the Fall-Line Motorsports rear lower control arm cup subframe bearing set. This is the essential rear camber arm inner bushing upgrade for serious road and track use on BMW G8X M3 M4, F8X M3 M4, F87 M2, E9X M3 and E82 1M. Replace the factory rubber rear camber arm bushings with motorsport-grade spherical bearings for sharper handling, improved alignment precision, better tyre contact and superior driver feedback. If you are searching for BMW rear lower control arm bearings, rear camber arm bearings, rear subframe cup bearings, spherical bearing conversion, or camber arm bushing upgrade for G80 G82 G87 F80 F82 F87 E90 E92 E93 E82 1M, this is the proven solution.
Developed from years of competitive racing, Fall-Line suspension components are built to win. These lower control arm subframe cup bearings use the largest FK spherical bearings on the market, with a full stainless bearing assembly and spiral locks providing 360 degrees of clamping to resist any movement under extreme load. By eliminating the rubber in this critical link, you reduce deflection in the rear camber arm, gain stability at the limit, and hold your alignment more consistently during hard cornering, braking and acceleration. Expect crisper turn in, more predictable balance and greater confidence on B-roads and on track days.
We have installed and used this kit ourselves, and our customers consistently praise the precise feel, durability and repeatable performance. Compared with OEM rubber, these spherical bearings also outlast typical bushings, reducing the need for frequent replacements over ownership. As with any spherical bearing conversion, anticipate a modest increase in noise, vibration and harshness, which is a fair trade for the handling gains.
