The rear sway bar has a large say in how a car balances. Stiffening it limits roll at the back and brings the tail around more readily, which many drivers use to lessen understeer and sharpen response. The bar is adjustable, so the stiffness can be changed to suit the car and the road.
Whiteline rates the install as moderate and lists about 1 hour. A wheel alignment is not required. To go with it on the WRX STI, see Adjustable Rear Sway Bar Link, Front Control Arm Lower Inner Front Bushing, and 14mm Adjustable Front Camber Bolts.
Features
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Warranty: Whiteline backs it with a warranty listed at 3 years and 60,000 miles.
