DC Sports CS-2 Front Upper Strut Bar is a quick and easy way to improve the handling of your 03-07 Corolla/02-05 Matrix. Tying together both strut tower allows for significantly reduced chassis flex and improved handling around corners and over uneven roads. Unlike multi piece aluminum strut bars that need to be constantly readjusted and retightened, DC Sports Struts Bars incorporate a single piece, steel design. This design ensures precise fitment that eliminates the need for retightening or adjustment in the future.
