Product Details
Owners of the 2017 BMW 330e iPerformance 3 Series (F30) can fit the Whiteline Front Lower Radius Arm Bushing. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. Included: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Order it as part number KCA473. It goes on the front of the vehicle.
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. Working on the same car? We also list Rear Lower Trailing Arm Bushing for the 330e iPerformance 3 Series.
Features
- Caster: Adds caster for steadier steering and better tire contact in roll.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Compliance voids: Molded voids give the bushing room to flex where it needs to.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Install guide: Whiteline packs an install guide with it.
