Product Details

Whiteline's note for this fit: Includes KBR15 Sway Bar Mount Support Brace: 3 Point Adjustable Motorsport. You receive 1 sway bar, 2 bushings, 2 braces, 2 lateral locks, 2 bolts, and 4 washers. Part number BSR49XZ. The chassis code on the listing is GR/GV. Position: rear. The listing names the Special Edition trim.
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. Adjustable mounting points let you step the stiffness up or down without changing the bar.
Installation is rated moderate, with about 1 hour of work listed. A wheel alignment is not required. To go with it on the WRX STI, see Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Front and Rear Sway Bar Kit.
Features
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Warranty: Whiteline's listed warranty is 3 years and 60,000 miles.
