Rookie Stock Cars

Overview: The Rookie Stock Class is based on the traditional BSA , RA,  Awana and other youth organization rules. It is the entry level class for beginning builders new to WIRL racing and wanting to develop building skills before competing in the advanced classes. Because of the difference in rules between various organizations, the Rookie Stock class rules are more lenient than the pure stock class. There is no maximum height or wheelbase restriction, and different wheel makes are allowed.

 Starting January 1st, 2007 A Builder may enter cars in the Rookie Class until he/she accrues 25 Rookie Points. After 25 points are achieved, the Builder and all the builder’s cars are promoted to one of the three advanced classes. The cars will be given a start date on the day of the first entry after promotion, and will be eligible to run 12 months from that day.

 A builder may elect to move up before 25 rookie points are achieved, or compete in the modified class along with Rookie Stock
