Another option coming soon for 4th Gens:

Seems like a good design -- would be interesting to compare and contrast with UMI's roto-joint versions...

BMR has billet aluminum lower control arms, but they are heavier than their regular tubular versions, so I'm assuming these arms are also pretty heavy. As for the bushings they are using, they appear to be the exact same design that UMI uses, and I've found those to still be a little too noisy for regular street use, at least to me.
They do look very nice, but considering the typical f-body owner balks at the price of most parts out there, I certainly don't see many at all springing for something this lavish, especially considering all of the other options currently available.

Ummmmm, why would someone spend that kind of cash for LCA's that are non adjustable, at least the UMI's are. Good luck centering a 28" tires in the rear with a set of those.

Hmm, I guess it is pretty much the same as the Roto Joint:

If they're too noisy for street use, sounds like it needs some more R&D...

I think it's just the nature of the beast.....if you take a bushing that has near zero deflection and has tight tolerances you're going to get increased noise and vibrations. That's why if you're looking for the best street manners, rubber bushings are the way to go. The roto-joints allow you to get the benefits of a rod-end with better street manners.
