As I mentioned before -10 front, and now -15 rear. Got a really good deal on the +0's else I would have probably went for the -15's. However, (someone correct me if I am wrong), I don't believe you get any more "lip" with the factory -15's, it is just a 15mm plate on the back of the wheel (basically the same as a spacer).
Also, in retrospect, -10 is about perfect in the front on the ZX anyway. In the rear I may have wanted to go a little larger for the look I'm going for. Although I really wish they made some 245/50 tires, had an older pair and I really liked the look (more muscle-car-esque).
Anyway, I attached I couple more shots.
