Launching harder, reducing wheel hop, and adding cornering consistency to your 2005-2014 S197 Mustang is easy with billet aluminum lower control arms from BMR Suspension. Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR’s billet aluminum polyurethane, non-adjustable S197 control arms (ACA004) are CNC-machined from 1.25x2.5-inch billet aluminum. This design gives you a strong, yet lightweight control arm that greatly improves performance. Two-inch greasable, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR’s bushings are internally fluted, which keep grease in the bushing, even under heavy load. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings. BMR Suspension designed the ACA004 to work well in street performance, drag race, and road race applications. The stock control arms flex under heavy cornering loads giving you inconsistent handling characteristics. Couple this with soft bushings that have massive amounts of deflection and you’re left with poor performance. The ACA004’s heavy-duty construction eliminates control arm flex, giving you much better 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 acceleration, yet offer plenty of articulation for great handling. 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! BMR Suspension’s ACA004 Billet Aluminum non-adjustable polyurethane lower control arms are available in a black anodized finish for long-lasting good looks. Installation time is about 1-2 hours.
