Whiteline built the Front Lower Radius Arm Bushing for the 2012-2013 BMW 335is 3 Series (E92/E93). Whiteline”s note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. This part is for the front of the vehicle. In the box: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Whiteline part number: KCA473.
Caster is the forward or backward lean of the steering axis, and more positive caster generally helps stability and steering return. This control arm bushing is made to add positive caster and alter anti-dive geometry, using a bushing swap rather than a major rebuild.
Installation is rated difficult, with about 3 hours of work listed. Plan on a wheel alignment afterward. To go with it on the 335is 3 Series, see Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Heavy Duty 20mm Rear Sway Bar.
