Just an FYI....Race City techs all vehicles to IHRA standards. These can be found in the 2008 rule book that is available at Mopac or Performance Parts. The NHRA rule book is also available at these locations too. If you have questions that you cannot find the answers to, come out to Race City and ask any of the tech staff (I recommend talking with Mike, he's been teching and building cars for years). We're there every friday, every second wednesday, and of course on race weekends.
