anyone use spc upper control arms??

We sell aftermarket kits at work from SPC but never sold the upper control arms cause not many people drive mopars around here. but i was looking through the catalog at work and noticed them they look pretty sweet anyone here deal with them complete camber and caster adjustments magnum force is a 5 min drive from me but i here most people like the RMS arms the best wanted to know opinions on these ones?
