The 1987-1988 speed density coupes were very fast. My 1988 is a no option coupe, weighs 3000lbs with 5/8 tank gas. I have been 12.90's with 3.73 gears, Hoosier quicktime pros, underdrive pulleys, 16 deg initial timing, 15/8 short headers and full 2.5 exhaust. Now the heavier GT's are a few tenths slower. It all goes back to the driver and how well the car works. The slowest of all the fox mustangs was the heavy convertable GT with the AOD, they ran 15.50's on the average stock.
Like any car, you can't judge by looks alone. You would never guess a Focus could run 12's or quicker, but some do. The same goes for Mustangs, some are slow, some are not slow............acutally very far from slow.
