I had to drive the #@$ out of my stang to get my 13.9, and on 225/60's but i must of hit those grs perfect
but 14.0's are no problem, just cant do any better for some reason, but now have a chip now,so 13's are back i hope.
And 13.90 in a heavy gt, on just one run is kinda hard to do?? maybe on sticky tires.
