Product Details
This Whiteline Heavy Duty 16mm Rear Sway Bar fits the 2008-2013 BMW 128i 1 Series. The kit contains 1 sway bar and 2 bushings. Whiteline part number: BBR46. Position: rear. Chassis code: E82/E88.
A sway bar is a torsion spring that links the left and right wheels. When the body leans, the bar twists and resists, which keeps the car flatter and spreads load more evenly across the tires. In general, a stiffer rear bar helps the tail rotate and reduces understeer. It is a fixed design with a single stiffness setting, which keeps it simple.
Installation is rated moderate, with about 1.5 hours of work listed. No alignment is needed afterward. Other Whiteline parts we list for the 128i 1 Series: Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
Features
- Roll control: Designed to cut body roll and sway through corners.
- Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Finish: Powder coat finish guards the metal against chips and corrosion.
- Lateral locks: Lateral locks stop the bar sliding sideways under load.
