sorry man, but your zip code is 3 hours away (w.o traffic). so an hour and a half is a little further than i'd like to go. I also wouldnt want to make you drive 3 hours to me.
would you willing to meet me half way for the wheels? zip code from me is 18062, *pick wherever you feel reasonable middle* i noticed you were pretty "close".
i have the same wheel sizes as the ones you listed, and you can deff drop it an inch or so with no problem. Eibach makes a camber kit for around $300 that you will need. You will need spacers though too. Prob 15mm and 25mm in the rear (i could be little off on the spacers)...mount them and see how much more they need to stick out.
Hey I see you are pretty knowledgeable about the offsets and wheels for the Z, I am about to buy some wheels, the ones I am looking at are 20x9 +20 and 20x10.5 +30, I am trying to figure out, without doing trial by error, what is the widest wheel size for the front and rear and tires I can put on without any rubbing. and if maybe I lowered my car an inch or two not having crazy camber where I would need to buy a camber kit. I see so many posts on here with a world of different offsets and tire sizes for a 20" wheel so it's kinda confusing. I want to have a real aggressive look.
Thanks.....
