The stock control arms flex under 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 TCA029s heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. The newly redesigned BMR Lower Control Arms feature multiple reinforced sway bar mounts (making them compatible with 2010-2011 FE3 and 2012-2014 Camaro FE4 suspension), and lots of adjustability to correct camber on lowered vehicles. An additional 1/4-inch of wheel clearance is also designed into the arms for 17-inch wheels. 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. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price, while maintaining acceptable NVH levels and ride quality. When performance is a must, rely on BMR's suspension!These arms require modification to be compatible with MRC equipped vehicles.BMR's suspensions TCA029 on-car-adjustable polyurethane lower control arms are available in red and black hammertone powdercoat for long-lasting good looks. Installation time is about 2-3 hours. Proudly made in the U.S.A.
