ProMedia is excited to announce the Chevrolet Performance Challenge Series class lineup for the 2017 racing season. All five of these hotly contested classes are returning to competition for championships in the CPCS again in 2017.

1. Wiseco Boostline Connecting Rods Drag Radial
2. Holley EFI Real Street
3. Chevrolet Performance Stock presented by Scoggin-Dickey Parts Center
4. LME Street King
5. Proform Rumble

There are some notable changes within these classes for 2017. With the extreme popularity of the LS Engine and its use in all types of performance vehicles, the NMCA and Chevrolet Performance have opened the rules for the Drag Radial, Real Street, Street King, and Rumble classes to allow the use of any make/body in competition provided it is LS- or LT-powered. The NMCA is excited to help Chevrolet Performance continue to market the LS and LT engines and their huge popularity in the performance market. Chevrolet Performance Stock presented by Scoggin-Dickey Parts Center will now permit the use of select manual transmissions. See the rules link for a list of those transmissions. Once again, Aerospace Components will have a major presence at all NMCA events, and winners will hoist up a Victor trophy in the Aerospace Components Winner's Circle.
