J&M Motorsports - 07-11 Mustang Shelby GT500 & 05-10 GT J&M Motorsports Double Adjustable Upper Control Arm Street
Just like the lower control arm bushings in the Mustang the upper control arm can have a significant impact on the vehicle’s ride, comfort, handling, acceleration, noise and vibration. When the car leans (i.e., rolls) in a turn, one side of the chassis moves upward relative to the rear axle, the other side moves downward, and the upper control arm must twist (rotate) to allow for the axle to articulate through its suspension travel. This rotation causes the control arm bushing to bind. If this bind becomes excessive, it will raise the rear wheel rate and produce sudden, uncontrolled, undesirable changes in handling (e.g., snap oversteer).

Don't let the race part scare you, we installed them in our 2011 5.0L Mustang and could not tell they were there, except from the lack of wheel hop when launching hard at the track.
