The newly redesigned BMR lower control arms feature reinforced sway bar mounts that make them compatible with 2010-2011 FE3 suspension as well as the 2012+ Camaro FE4 suspension. The overall length has been shortened 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!NOTE: TCA028 is not compatible with the factory rear sway bar end links. Part number ELK006 is required to retain the rear sway bar. Designed for lowered vehicles only. Use on OE height vehicles may not provide adequate camber adjustability. Due to shortened length of these control arms, adjustable toe rods are necessary when using this product.These arms require modification to be compatible with MRC equipped vehicles.BMR's suspensions TCA028 on-car-adjustable polyurethane lower control arms are available in red and black hammertone powdercoat for long-lasting good looks.
