SACRAMENTO, Calif. — The Northern Auto Racing Club (NARC), sanctioning bodies and sprint car race promoters throughout California and the West Coast have agreed to implement a fire suppression system rule in 2023. Effective May 1, 2023, all sprint cars will be required to run a fully functional system meeting a SFI 17.3 specification. This includes the Sprint Car Challenge Tour, Kings of Thunder, Skagit Speedway and all tracks on the NARC 410 sprint car schedule. The equipment specifications mirror what most major sprint car sanction bodies are requiring during next season. A complete breakdown of the rule will be published in the NARC rulebook in early January.
