Time for the driver mod, for sure.
A stock spec B can run more than a second faster in the 1/4. You're missing a few MPH, too. Get that sixty foot down, however, and you'll be on your way...
I made it to the track twice in my WRX. The stock run has a similar MPH to yours, but look at the difference in ET because of the 60'! Every tenth there gets you two tenths at the line.
Practice, practice, practice, and don't be afraid to break things
