The COBB 02-07 Subaru WRX Anti-Sway Bar Kit is one of the most effective ways to improve handling without negatively affecting ride quality or NVH. The perfectly balanced kit increases front bar stiffness to 880 lbs/in and rear bar stiffness is adjustable from 460 lbs/in, 560 lbs/in, or 690 lbs/in to resist body-roll, sharpen turn-in response and reduce understeer. The CNC bent anti-sway bar kit includes rear mounting brackets and stiffer polyurethane bushings with bushing brackets for instant suspension response, and all are direct factory replacements to ensure perfect OEM- like fitment without compromising performance. The bushing brackets also include built-in grease fittings to make maintenance quick and simple. The COBB Tuning Anti-Sway Bar Kit is compatible with stock and most aftermarket end links.
