NHRA Technical Department announces rules for the 2015 Factory Stock Showdown. In addition to these rules, the cars must also meet all requirements as outlined in the 2015 NHRA Rulebook. The competition includes entries from two Stock Eliminator classes with each class running as a separate category within Stock Class Eliminations, and a winner being crowned in each. The two winners will then square off for the NHRA Factory Stock Showdown Championship using a handicapped start, based on the quickest run of each class winner. Each of the two class winners will receive the NHRA Class Wally trophy with the run-off winner being crowned the NHRA Factory Stock Showdown Champion. If you have any additional questions, please feel free to contact the NHRA Technical Department at TechDL@nhra.com.
