Which brand? You need this info to make an informed decision. If it ends up being a 9.5" for the front I wouldn't go above a 275 tire. A 285 will fit but won't be optimal, especially for the front.

GT With a PP is still quite a bit less expensive than a base DH. I ordered a SY GT, 400a, 6 MT, PP, red brembos and AE and the car stickers for $56k. A base DH is right at $60k.
The PP is really worth it on the feel of the car on its own. It firms it up when even a PP car is still pretty soft. The Torsen rear end and the Brembos are the main selliing feature. If you like the spoiler of the PP than thats another. With the S550 there were other items that made it...
First off are you getting any deal at all for the special order car? If not and you can live with the color that is already available I would move forward with that.
The PP on the Mustang is the last benchmark I would look at. The PP cars are so undertired. You have a 3900lb car with a 56/44 weight distribution and only a 9" wide front wheel with only a 255 tire.
To the OP, rethink your wheel choice I wouldn't go below a 10"wide wheel for the front...
That is a perfect Mustang fitment. I ran Mich PS4S up front and the Mich PSS out back (no PS4S in 305/35/19). My S550 with this setup..I will be running the same setup when my S650 arrives.
I live in the South Bay in S. California. My dealer is South Bay Ford which services Manhattan Beach, El Segundo, in other words they are pretty exclusive areas. They treat the cars with a lot of care. Also, it depends on you. You have to let your SA know that you are a picky Son of a Bitch...
