The stock control arms flex under cornering loads giving you inconsistent handling characteristics. Combine this with soft rubber bushings that have massive amounts of deflection and you're left with poor performance. The TCA001's heavy-duty construction and polyurethane bushings eliminate unwanted deflection, giving you much improved repeatability on the street, starting line, or in the corners. BMR's polyurethane bushings are 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. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price, while maintaining acceptable NVH levels and ride quality. BMR Suspension designed the TCA001 to work well in street performance, drag race, and road race applications. When performance is a must, rely on BMR Suspension! .
