Whiteline Rear Subframe Mount Bushing for 2017-2021 BMW 230i 2 Series (F22/F23)

Whiteline built the Rear Subframe Mount Bushing for the 2017-2021 BMW 230i 2 Series. Order it as part number KDT917. Chassis code: F22/F23. The kit contains 8 bushings, 4 tubes, an install guide, and grease. Position: rear.

The rear subframe is the cradle that the rear suspension arms bolt to, and the car is attached to it through rubber mounts that are soft on purpose. That softness lets the subframe shift under hard cornering or acceleration, which dulls the feel of the rear end. A firmer bushing set holds the subframe in position, so the rear responds more directly to steering and throttle.

Whiteline rates the install as difficult and lists about 4 hours. Get the car aligned once it is back on the ground. Other Whiteline parts we list for the 230i 2 Series: Adjustable Rear Sway Bar Link, Front Sway Bar Link Assembly, and Rear Lower Trailing Arm Bushing.
