Ok Here is a picture of my car with the 17's and 275/50/17 on the rear and 255/50/17 on the front. If you go any lower on the front the tires will rub on the wheel housing bolts on a hard corner unless you have super stiff springs. The rear could stand to be lowered but the SSM lift bars sort of prevent that. As well, I have some old air shocks installed back there which I haven't yanked off yet. I have new ones sitting here, but just haven't gotten around to installing them.
