The stock control arms flex under even light cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and youre left with poor performance. The UTCA021s heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMRs polyurethane bushings are designed to be compliant enough to give you a comfortable ride and absorb NVH, while remaining firm enough to stand up to high loads of any performance environment. The bushings easily handle the high compression loads of hard launches and hard acceleration, yet offer plenty of articulation for great handling. The UTCA021s also allow you to retain the factory air ride with no special mounts or brackets are required. These are the perfect upgrade for the enthusiast looking to improve performance, while maintaining acceptable NVH levels and ride quality.
