Four drag racing clubs will unite at Firebird Motorsports Park for an exciting two-day competition. Visiting organizations West Coast NA and AFX will demonstrate their expertise on the 1/8-mile track, while Arizona's own AZ Grudge Racing and Cordes Performance Racing present both 1/8 mile and 1/4-mile racing classes, highlighting top local talent. Those interested in challenging WCNA or AFX can purchase a tech card and participate, with cash buy-ins available at each club’s booth in the pit area. For racers wishing to compete locally, AZ Grudge Racing (1/8 mile) and CPR’s 1/4-mile index offer ideal opportunities. Additionally, the Open Test N Tune class allows participants to test new setups.
