We can move the discussion here.
Depending on how low you are, you could get away with natural camber all around, but you would have to be really low and have to pull a lot. I had -3.5 front and -4.5 rear naturally. However, -4 front and rear or -4 front -5 rear would do the trick. For the rear I would definitely suggest Wicked Tuning, and the front your best bet would be Ingalls probably. You will have to cut your strut towers with the Ingalls on, unless you don't mind your Upper control arms sitting on the strut tower.
Wicked Tuning is the best for a rear camber kit IMO. SPC is pretty good for the front. If you want to go as low as Brent or lower, you'll need to cut a hole in your strut towers for the control arms not to smack constantly. Also Sleeper Cell on here makes a kit for the rear that is supposed to be high quality. Basically you'll get out whatever you put into it. Go cheap and you'll get cheap results. Good luck
