Looking for a front radius arm bushing for your 2008-2013 BMW 128i 1 Series (E82/E88)? The Whiteline Front Lower Radius Arm Bushing is made for it. Application note: Adds +/- 0.5 degrees Caster. Order it as part number KCA430. You receive 2 bushings and 2 tubes. This part is for the front of the vehicle.
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.
Installation is rated moderate, with about 3 hours of work listed. Plan on a wheel alignment afterward. Working on the same car? We also list Adjustable Front Sway Bar Link, Rear Subframe Mount Bushing, and Heavy Duty 20mm Rear Sway Bar for the 128i 1 Series.
