Gentlemen, Better work fast if you plan on participating at Mid-Ohio. The pre-event school had less than 5 openings still available. The registration for wheel to wheel race cars has topped 30 and total participant registration which includes the Viper Days Challenge series is past 90. If you come to watch, this would be the one to come to. Possible the best event of the year at a legendary track where the SCCA nationals is held every year. Last year this race set the tone for all of the events of the year. The racers get committed or not based on this one. There will be a semi truck with mobile dyno that will be evaluating all wheel to wheel cars for power. A possibility if you are curious on your own car. You may look into this by going to the ViperDays.com page.
