BMR's polyurethane, non-adjustable control arms for Mustangs (UTCA057) are CNC-machined from 6061-T6 billet aluminum. This design gives you an incredibly strong control arm that greatly improves performance. Greasable, high-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR's bushings are internally fluted, which allows grease to evenly coat the inner sleeve. 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 UTCA057 to work well in street performance, drag race, and handling applications. The stock control arm bushings deflect excessively under cornering loads giving you inconsistent handling characteristics. The UTCA057's heavy-duty construction and strong polyurethane bushings give you much improved repeatability on the street, starting line, or in the corners. The UTCA057s are primarily designed for lowered cars that are looking to remove the camber gained from lower than stock ride height vehicles. These are designed longer than factory arms, give you the ability to correct the camber setting on lowered S550s. ALL lowered cars will benefit from these parts IF you are looking to remove negative camber. For those looking to GAIN negative camber, these are not the correct choice. With a 1.2-inch drop, the most negative camber you can get will be approximately -2.0 degrees. These work very well for drag racers who have lowered ride heights, and are looking for ZERO camber. BMR's heavy-duty spherical bearings are designed to solidly link the spindle to the upper control arm, eliminate deflection and wheel alignment changes. On stock height cars, you cannot exceed -0.50 camber. BMR's S550 upper control arms add no noticeable NVH. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price.
