Ok, Looks like if all goes well I will be the proud owner of an 07 mustang GTthis weekend. Im not looking for a loaded up one (shaker, leatherand stuff,I can add what I want later on) but as far as factory options like the rear end and things like that what do I need to look for, What are some of the things that you guys wished you would have added on to a new car. I saw an option for a 3.31 ( I think) geared rearend. Is that something I want, what does it have if the 3.31's arnt in it.
you want the 3.55 rearend if this is a 5 spd, unless you are going to get 3.73, or 4.10's later on. The 3.31 is stock, so the upgrade would be the 3.55's I beleive...
