Stock upper control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. The factory arms also don't allow for proper camber correction on lowered vehicles. BMR's Delrin, non-adjustable control arms for Mustangs (UTCA064) are CNC-machined from 6061-T6 billet aluminum. This design gives you an incredibly strong control arm that greatly improves performance. Greasable, solid Delrin bushings add a solid, more responsive feel over the stock rubber bushings. The stock control arm bushings deflect under cornering loads giving you inconsistent handling characteristics. BMR's Delrin bushings are designed to eliminate deflection, while being able to stand up to high loads of any performance environment. The UTCA064's heavy-duty construction and solid Delrin bushings give you much improved repeatability on the street, starting line, or in the corners. The UTCA064s 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. Our spherical bearings will stand up to high loads of any performance environment, offering all of the bind-free suspension articulation needed for great handling. On stock height cars, you cannot exceed -0.50 camber.
