I have a pretty much stock GN. The only mods I have and will be adding soon are an adjustable wastegate, adjustable FPR, 3'' ATR downpipe with 3'' cat and Hooker exhaust, a new turbotweak chip, 42.5 lb/hr injectors, some QA1 adjustable shocks up front, and Edelbrock IAS's in the rear, with some new springs and air bags. I am also ordering some 15X8 Centerline Telstars for the rear and was wondering if I should go with MT DR's or MT Drag Slicks? These tires will be for track use only by the way. Thank you.
