Attention Racers!
All Racers must have a MyLaps Transponder in order to be scored! There will be a limited amount of rentals available for Nationals but it would be best to have your own. Westhold transponders do not work with our system.
It is also MANDATORY for all Micro Sprint and Wing Kart drivers to have a Raceiver in order to race!
Thanks!
