Thanks guys.
Now, so I do not have to go outside to look, What is the tire size? I have the upgraded 17" wheels (im assuming they are the same size as the 17" bullitts).

...hey guys, isn't it possible he has the 3.55 option or was that only offerred on mt mustangs?

I remember reading that the 3.55 option was only for manual transmissions. I could be wrong. I still have my order sheet at home, if somebody hasn't answer by tonight I'll post exactly whats on the sheet. I can imagine what the difference would feel like going from 3.31 to 3.73.

I have seen 3.55 on an auto 07. Funny thing about it was the sticker showed a higher MPG than 3.31s. I asked about it then, but nobody answered why the mileage would read higher on the 3.55s. I actually went back and forth between two cars trying to figure out what was different on the sticker. Both were auto's. Both were GTs. NOT a V6. I Think the 3.55 equipped car had 18" wheels. I dont see how that made a 2 mpg difference. Couldnt see anything.

I think the 06 GT auto was 3.55 also....not totally sure though
