Their products seem to be top notch. I am going with their competition subframes and probably would have went with their LCA's if I didn't already have some.
I would give them a call and talk to one of their Engineers or tech guys.
I have them on my car and they are good. If I had known about Metco before I had the Gobal West installed I would have gone with the Metco all the way around.
I have them and they are great. I got the set with spherical aircraft bearings on the frame side and a DEL-A-LUM bushing on the rear-end side. The car handles like it is on rails and it rides much smoother that before. I was really surprised that it rides smoother, didn't expect that. They are noisy as hell though. The tire noise really carries into the car from the rear end on my convertible. I would get the polyurethane bushings intead of the DEL-A-LUM if I had it to do over again.
I am running BFGoodrich KD 265/40 tires which are noisy as hell. It wasn't nearly as noisy with the original 245/40 BFGoodrich TAs. These tires are LOUD. The control arms just make it worse.
The MM control arms would probably be quieter since they have the spherical joint on the axle end instead of the body.
