What does it take to get a street Mustang GT into the 12's? I'm talking about tires and wheels you would drive around on every day, WITH the back seat, etc.
well the search button will get you into the 9's easily just by itself
but in all fairness, a custom tune from a SCT X cal II, JLT CAI , 4.10's, BFG goodridch KDW2's, big rims/tires out back, Springs, panhandle bars to eliminate wheel hop, Axle back, O/r Mid-pipe and that should easily throw you into the 12's
