Outlaw Street is a heads up class for all types of vehicles. Cars may utilize full tube chassis or back half chassis. There are no restrictions on front or rear suspension other than NHRA requirements. Legal combinations include the use of nitrous oxide, supercharger, turbocharger and normal aspiration at different weight breaks for parity. All entries compete on a Mickey Thompson 33 x 10.5W x 15 or smaller tire.

The allowed procedure is both competitors pre-stage, then one stages and the other stages within seven seconds. Failure to stage within the time limit results in automatic red light for the delaying party.
