i believe first he's got suspension upgrades to reduce the understeer, then an exhaust will be coming out which saves 50 pounds over the old system. He will also have throttle bodies and dual carbon fiber intakes for it. Supposedly all the bolt ons will bring power to about 450-500 horses. A supercharger kit will be available sometime next year to bump it up to about 600 horsepower. He is also working on headers which will increase power by about 36 horses. All this info is straight from steve himself. I had the pleasure of meeting him at Habberstad BMW on Sunday.
