I asked a few of the SRT guys and they said they're all in street prepared. Street mod is where you end up if you change your turbo (for the most part). Everything else puts me into street prep though, so I'd be there with street tires. Someone mentioned the sidewalls on the drag radials was too thin/flexible and wasn't a good idea to auto-x in them. Makes sense. I checked to see what else was in my class. I plan on getting my ass handed to me by a few Miatas and Hondas. My car is actually big for its class, haha.
