Hey guys I am stuck in Korea without my car otherwise I would go find out the answers to the questions myself. First question is what is the bolt pattern on 02 GT? Second question is on a stock 02 GT with the stock wheels and tires what is the overall tire height? Thanks in advance guys.
Do you have the 2002 Mustang GT Premium Package? If so, then you have 17x8 rims, and probably the same tires that I have: Goodyear Eagle ZR45 245/45/17. If that is the case, if you have 245/45/17 tires, then the diameter is 25.7 inches.
Here's a nice URL for calculating tire diameters. Note that it does not work with Firefox (unless you want to download the Java Runtime Environment, which I don't want to do, for security reasons). It only seems to work with Internet Explorer:
