J&M Motorsports - 07-11 Mustang Shelby GT500 & 05-10 GT J&M Motorsports Ultimate LCA J&M street/race Lower control arms in flat black powdercoat. 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. These steel arms are the lightest and strongest LCA available. Billet arms are just for looks, they do not perform any better and actually weight more. We are using these arms in all our shop Mustangs and recommending them for customers cars due to their superior bushing design. A high quality poly bushing is used on the front, and a hyrbrid poly-ball bushing design is used in the rear. The poly-ball gives you the best of both worlds, tight heim-joint like locating but the NVH reduction of a poly bushing. No problems with bushing failures like some other manufacturers, we used these arms to solve that problem in our 900HP Shelby GT500.
