2021 Time Trial Rules
2021 will see the kick-off of a Lone Star Chapter Time Trial run group as part of our May 29th & 30th HPDE Event. Time Trial is a supplement available for our Advanced students and Instructors which will run in a separate run group with transponders attached to each car for live lap timing. Information below will assist you in determining which sub-group your car is classified in.
