I'm planning on autocrossing mine as well. How does it do? I have a 57 trim turbo (running stock boost right now), how much boost are you running? Planning on adding a boost gauge, hardpiping, and MBC next. It has stock suspension (TEMS) and 16" sawblades with street tires. What brand tires are you using? I was considering stepping up to 18" or 19" after I kill these, but didn't know if it was worth the $$.
