If only you were in So Cal, I would sell you mine for $1000 as long as you traded my your front struts for mine. I have a kit similar to the one Universal Air has, but I pieced mine together for about $1,400 cuz I originally got manifold air valves but had to replace them since they were always stock open. In other words, it's cheaper to piece a kit together, but buying a whole kit usually saves you a lot of headaches. Oh yeah, and stay away from manifold style air valves. Pretty much everyone I've talked to who's had them had the same problem I had with them sticking open, including Randode.
Randode also has a great set up and it's not as expensive as the rest.
