I got 17x8s front and 17x9s rear. The rear has 275/40. Plenty of room in back. Prolly could lower close to 1" and still be ok. Mach's are 1/2" lower than stock GT, so that'd be nearly 1-1/2". Front are stock size. I haven't seen too many tire companies have 275/45 tires, that would be perfect for my setup. I think ColeJohnson is running w/305s and is lowered. Checkem out.
