Product Details
Looking for a front radius arm bushing for your 2005-2018 BMW 330i 3 Series (E90/F30/G20)? The Whiteline Front Lower Radius Arm Bushing is made for it. Position: front. In the box: 2 bushings and 2 tubes. Application note: Adds +/- 0.5 degrees Caster. Whiteline part number: KCA430.
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.
Expect a moderate job of about 3 hours. Get the car aligned once it is back on the ground. To go with it on the 330i 3 Series, see Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
Features
- Grease: Molybdenum disulfide grease is included to help the parts last.
- Finish: The metal is powder coated, which resists corrosion and wear.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
- Caster: Adds caster for steadier steering and better tire contact in roll.
- Install guide: Written install instructions are included with the part.
- Material: Made from polyurethane.
