The 2019 NMCA and Chevrolet Performance Challenge Series Preliminary Rules are <HERE> Thank You to NMCA and Chevrolet Performance Challenge Series racers and sponsors who have submitted rule requests for the 2019 season.

We would like to remind racers that these are still considered preliminary rules and we value more input. Please present your rule suggestions to the NMCA Tech committee no later than November 26, 2018 [email protected]
