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 you're left with poor performance. The UTCA002-1's heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMR's 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 adjustable design allows for fine-tuning of the pinion angle for proper driveline alignment. These are the perfect upgrade for the enthusiast looking to improve performance, while maintaining acceptable NVH levels and ride quality. When performance is a must, rely on BMR Suspension!
