Progress 22mm Adjustable Front Anti-Roll Bar Kit 2008+ Subaru WRX STi

Progress Suspension anti-roll bars dramatically improve handling.  How?  They minimize the traction-robbing body “lean” that rolls part of the outside tires off the pavement.    Our Sport-tuned Anti-roll bars replace skinny OEM bars and rubber bushings with larger diameter (stiffer) alloy steel bars and polyurethane bushings.  More roll stiffness means less body “lean”, and the tires stay flatter on the pavement (larger contact patches).  The result is more grip and added driver control!
