Product Details
This Whiteline Front Lower Radius Arm Bushing fits the 2016-2020 BMW 420i Gran Coupe 4 Series. This part is for the front of the vehicle. The kit contains 2 bushings and 2 tubes. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. The chassis code on the listing is F36. Part number KCA430.
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.
Whiteline rates the install as moderate and lists about 3 hours. Plan on a wheel alignment afterward. To go with it on the 420i Gran Coupe 4 Series, see Adjustable Rear Sway Bar Link and Front Sway Bar Link Assembly.
