Product Details
Here is the Whiteline Front Lower Radius Arm Bushing (Double Offset) for the 2015-2016 BMW 428i Gran Coupe 4 Series. Part number KCA473. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. It is listed for the F36 chassis. Position: front. Included: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease.
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 difficult and lists about 3 hours. An alignment is required after installation. Other Whiteline parts we list for the 428i Gran Coupe 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.
Features
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Grease: Moly grease is supplied to prolong the life of the parts.
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Compliance voids: Voids molded into the bushing allow suspension articulation and soften sharp road inputs.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
- Corrosion protection: The hardware is plated to stand up to road conditions.
