Very nice pass for a car that's not ment to leave hard (no offence) I'm guessing your 60' on the 12.2 pass was around 1.69-1.70?
Air up the front tires lower the pressure in the rears, Do a SMALL SMALL BURN OUT (street tires don't like heat) and shallow stage. Maybe make a run at night (cooler weather and track) You'll break into the 11's...

I'm kinda a rookie at drag racing though
