For anyone still registering for the Time Trials event, you will now need to supply your own AMB transponder. We have ordered our supply, and they are all spoken for. Without a transponder, you will not receive lap times and thus not be eligible for the class awards.
Autocross participants are not affected by this update. We've got the wireless T-link system ready to go!
