Progress Rear Adjustable 22mm Anti-Roll Bar Subaru WRX STI 08+

Progress Anti-Roll Bars dramatically improve handling. They minimize the traction-robbing body "lean" that rolls part of the outside tires off the pavement. Sport-tuned Anit-roll bars replace skinny OEM bars and rubber bushings with larger diameter (stiffer) alloy steel bars and poyurethane 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.

Progress Ant-Roll Bars are cold-formed in-house using their custom built precision bending equipment. Both laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit.
