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.
