Due to idiots claiming the TTA is a low 13 car, I now claim the fox body Mustang is a mid/high 13 car from the factory. The TTA can BARELY manage a 100mph trap speed. Low 13's with 100mph trap means a sick hole shot and 99.9999999999% of drivers can't pull that off. I say that because considering trap speeds, the 87-88 GT's could easily match the TTA in performance, in a straight line. They are equal in power to weight.
I've also seen timeslips listed for a 1997 Gen I 4.6L bone stock convertable at 14.7sec with a 2.2sec 60ft. Since I know that's impossible, I chalk it up to a screwed up race track. This is to what I attribute 13.2sec TTA's which are bone stock. Screwed up tracks or people who have cars that get faster as they get older.... I remember back when my 1971 El Camino pulled off a 15.2, five years later 14.2, ten years later 13.2, 20 years later 12.2... etc.
The new Mach 1 is an ultra low 13 car from the factory.
The 1994-1995 Mustang GT is a low/mid 14 car from the factory.
The 1996-1998 Mustang GT is a mid/high 14 car from the factory.
The 1999-2003 Mustang GT is a mid 13 car from the factory.
I'm not a mag racer, and I'm not a ricer so unlike 99% of F body owners and ricers, I don't quote the best times possible from the cars I drive, but I feel there is no choice in this matter except to point out how quick the GT's truly are.
