Why not just get a 2004 Sti ? ? It pulls 13.2 in the 1/4 mile stock. Faster than all but a few Porsche's, only a hair behind the Z06 Vette, and would smoke nearly every BMW as well. An Audi is not the way to go, unless your talking engine wise. Then maybe swapping a Audi TT engine into a Golf might be nice. But 13's probly wont happen.
