Brahma12,
I have:
-Einkei LM1 18x7.5 's
-Yokohama 215x35x18's
-Eibach Prokit Springs (about 1.5 inch drop)
With this setup I rub in the back right with two or more people in the car. ended up taking a TON of rubber off the wall of the back right rim before I rolled it a bit. I still rub since I'm still trying to find a fender roller to complete it. I would advise that if you do get 18's for your ride make sure you get shocks and struts at the same time. My offset is 45 and I really wish I would have gotten the Illumina's the same time. I'm pretty sure that would prevent any massive rubbing I have now. Hope this helps.
