I have been all over the WEB and looked at thousands of photos, just looking for any real life experience.

I put the tires from my 2001 Bullitt on the boys 01 V6 car with some craigslist GT wheels, and the wheels for the Bullitt were only made in 01-02 (different color than others, so I have them stored. All this as an excuse for the ability to go by wheels and bigger/wider tires, better off-set to fill the wheel wells.

The stock wheels and tires:
17x8 with 5.68 BS and 245-45-17 tires (25.68" tall)

I know MS said he had put a set on his daughters car that had no issues that were 17x9 , 275-40 front and 17x10.5 315-35 rear. This is an extremely popular choice and looks great, but the fronts all appear to stick outside the wheel wells and the rear look odd unless you lower the car (my bullitt sets 1" lower than a standard GT).

The second popular choice is 18x9 265's and 18x10 295's, same issues as well as a lot of people talk about rolling the fender lip and I dont want to do that.

I also worry about the front tracking with the tires too wide.

I am thinking 18x8 (stock back spacing)with 245-40 front & 18x9 (5.94" BS and 1" wider, sets the outside lip 3/4" further out) 285-35 rear, a 285 setting out a little further should be a noticeable change from the 245, and I could always use a 1/4"-1/2" spacer.
