So I'm planning on getting some 18x7.5 rota subzeros w/ an offset of +40 and I'm trying not to have the wheels butterfly. I've been hearing lower it first to compensate for the camber. So now I'm looking at either the tanabe df210 the trd lowering springs, tein, and eibach. Any suggestions? And what do I do if they still butterfly? Will sway bars help any? Thanks in advanced!
