Notes:
If you happen to already known a Yellow or Kart Transponder they may or may not work with your race vehicle. The difference between a car and a kart is the speed they will register at
X2 Car are good to 161 MPH
X2 Kart are only good to 75 MPH
If you are close to 15 second lap times you may be over the 75 mph line and the kart transponder will not work in that case.
If you chose to use a Kart transponder and your laps do not register please be advised that you will not be scored for the event.
