The rear trailing arm bushings on an E36 or E46 M3 are soft and often decades old. Under power and braking they let the rear axle steer itself. The Fall-Line Motorsports Rear Trailing Arm Monoball Conversion Kit replaces them with spherical bearings so the rear tracks true.
The thrust arm moves smoothly through its travel instead of binding and flexing, and the car feels tied together again.
Monoball Conversion for E36 / E46 M3 Trailing Arms
A precision-machined aluminum housing holds a spherical bearing that eliminates bushing deflection under load, preventing unwanted geometry changes and hysteresis. Made in the USA.
