Those are pretty much the best times people run in those cars…for those times it had to be perfect weather and track prep. I know I heard of some 12.6 stock cobra’s but most are 12.8-13.1…mach 1’s I see a ton are 13.8 or so…but I have seen a few run low 13’s, for the 01 GT most I see stock (I guess you can call them stock since everyone I have seen has flowmaster) run around 14.0-14.5. But is your times are legit I give props that is getting everything out of those cars for the most part. (in pgh)
