Grassroots Motorsports Skidpad Challenge Rules
This event is meant to be a fun editorial exercise so that Grassroots Motorsports can show its readers what cars, layouts and modifications tend to grip better. Vehicles found in violation of the spirit of the event may run for exhibition.
The competition will consist of a one-day event at the skidpad located in the infield at Turns 6 and 7 at Road Atlanta. Entrants will run on a first-come, first served basis. Only one car will be present in the skidpad at a time. Upon arrival, entrants will proceed to the registration area to check in.
Complete competition and scoring format coming soon. Stay tuned!
There is no entry fee for this competition. However, competitors will need to purchase a Sunday ticket for the Speedfest at the Classic Motorsports Mitty in order to gain access to the skidpad. Entrants must register at least 1 day before the event.
Any four-wheeled car is allowed as long as it passes the safety requirements. If you believe that your car meets the spirit of the rules but not the exact letter of the law, contact us to discuss eligibility of your entry.
