I have a 2008 g35 sedan and I am looking to get some 19" rims. I want both the front and rear tires to have the concave look and want the tires to pretty much be flushed. I don't want them sticking too far out. My car is stock right now and eventually I will drop it 1 inch. So I need some help figuring out what tire sizes and offset I will need. I don't know how to go on about figuring that stuff out. please help?
