Product Details
Whiteline Heavy Duty Blade Adjustable 20mm Rear Sway Bar is made for the 2010 Subaru WRX STI Special Edition. Application note: Includes KBR15 Sway Bar Mount Support Brace: 3 Point Adjustable Motorsport. Chassis code: GR/GV. Position: rear. Whiteline part number: BSR49Z. You receive 1 sway bar, 2 bushings, 2 braces, 2 lateral locks, 2 bolts, and 4 washers. The listing names the Special Edition trim.
Roll control is shared between the springs and the bars, and the rear bar is the easier one to use for fine tuning balance. A stiffer bar keeps the rear flatter and moves the car toward a more neutral feel. 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. Other Whiteline parts we list for the WRX STI: Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Rear Subframe Mount Bushing.
Features
- Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
- Lateral locks: Lateral locks stop the bar sliding sideways under load.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Roll control: Built to reduce body roll and sway in corners.
- Adjustable stiffness: The bar has more than one mounting position so stiffness can be tuned.
- Finish: Powder coating covers the metal for protection against chips and rust.
