I'm about 2 days away from pulling the trigger on some air-shocks as well, and I still have my doubts. Coilovers would kill my budget. My car is a little lighter than the OP's car, around 1000#s empty, 1300#s with me and a passenger. Using 3x3s/930s with about 12" of travel.
I've never ridden in an air-shock car, so I have no idea what they're like. I've heard all sorts of bad things; that they're uncontrollably bouncy off jumps, too stiff over whoops, and unstable in turns. I can't tell if that's just dual-sport haterade, or what.
So, what about the ride quality? Are they too bouncy on landing? Who makes the best air-shock for sand? Anyone using them recently want to tell me what I'm getting into?
