Maximum Motorsports control arms vs UMI

So I came across this new company called UMI. Apparantly they make alot of suspension parts for GMs. Anyways I was looking at their lower control arms and Im actually quite impressed. I really wonder how these stack up to against the MM arms. They look to be constructed well and have spherical ends on the axle side. I know that typically it is bad to have Poly bushings in the rear control arms because of bind, but they only put it on the chassis side of the arm.....just like Maximum Motorsports.

Does anyone have any first hand experience with these arms? Any flags that go up in your mind after reading their description?

While I do sell lots of Maximum Motorsports stuff and think it's great (and I'm not alone on this), I can say that the UMI stuff works just fine. Another value option would be UPR, which I helped install on a friend's 408'd Fox. They're about the same price range, and for the limited driving that he's be doing with it, it has turned out to be a pretty good bang/buck choice for him.

I guess it all depends on what you're going to be doing, how often, and what your wallet says. From us, the heavy duty MMLCA's would only cost another $50 or so (and a little birdie told me that may go on Christmas sale to drop that amount even more :))
