Product Details
This Whiteline Front Lower Radius Arm Bushing fits the 2017-2021 BMW M240i 2 Series. You receive 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. It goes on the front of the vehicle. Part number KCA473. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models.
This kit does more than replace rubber. Its offset design moves the pivot point of the lower control arm to add positive caster and change how the front end resists dive under braking, which improves straight-line stability and turn-in feel.
Expect a difficult job of about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the M240i 2 Series: Rear Subframe Mount Bushing, Rear Lower Trailing Arm Bushing, and Rear Differential Mount Bushing.
