I just bought a 98' Trans Am, M6. The car is 100% BONE STOCK with 63,xxx miles, NO free mods, and has some very hard all season tires on it. I went to the track yesterday and best pass of the day was:

60 - 2.112
1/8 - 8.861 @ 81.52mph
1/4 - 13.59 @ 104.476mph

Anyways, I *think* that is a pretty decent time for the way the car is sitting right now and seeing how it spun a little through the sixty and would spin if I shifted fast.

 

Congrats on the times. With some good soft tires you should be in the low 13s very easily. Get some Nittos and see what you can do!

 

The time is not bad at all.
