Suspension Secrets Eccentric Rear Control Arm Roll Centre Correction Bushes — BMW F80 M3 / F82 M4

When lowering your M3/M4, roll centre is an often-overlooked but important aspect of geometry that needs correcting. Roll centre position determines how stiff the car feels through corners, and can make the car unpredictable on track if altered too much by lowering.

This eccentric bush replaces the OEM solid bush where the rear lower control arm (coffin arm) attaches to the upright. Installed in the correct orientation, the offset bush corrects rear roll centre — significantly improving handling and stability.

Fits BMW F80 M3 and F82 M4 (2014–2019).
