Your forget to mention you have a stripped cloth interior you dont use power steering you have suspension mods and a few other tidbits...
I have FULL leather interior(200lbs) I use power steering{-4whp) I have no suspension(-traction) and only have a total of 20 drag strip runs in my life under my belt...
I am not worried... I feel there is a 14.5 in the car full interior - street trim.
I alo feel there will soon be mid 12s in the car with the same...
