With a significant increase in the number of full-time teams confirmed to compete in the 2019 IMSA WeatherTech SportsCar Championship, the sanctioning body may need to restrict the number of cars at some events.
At least 37 full-season “premium” entries already have been filed for the 2019 season.
With pit lanes at Mid-Ohio Sports Car Course and WeatherTech Raceway Laguna Seca able to accommodate maximum fields in the low-40s, restriction protocols may be deployed for the first time since the inaugural WeatherTech Championship season in 2014.
