BMR Suspension designed the MTCA030 control arms to work well for street performance, drag race race applications. 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 you're left with poor performance. BMRs lower control arms have been redesigned with a lightweight, yet strong construction that eliminates control arm flex, giving you much improved repeatability on the street or starting line. The arm is designed to work with 15-inch wheels as part of BMR's Drag Race Rear Suspension Package. BMR's Delrin bushings eliminate bushing deflection and transfer the maximum amount of torque and horsepower possible. This means better throttle response, quicker 60-foot times, and improved all-around performance. When performance is a must, rely on BMR Suspension!
