jason if you are trapping almost 113mph you should be able to hit low 12s. you're best so far is a 12.7? what was your 60' in that run? say it was a 2.1, you put tires on there and pull a 1.9 that .2 sec faster. .1 in the 60' usually translates to .3sec faster in the 1/4. so going by that you should run a 12.1 about.
