Hung-Jen… Any changes to the car you’re bringing to an event do not happen in Motorsportreg.com. I don’t even see that data when I’m preparing run groups for an event.
Any car changes must happen in our online classification system prior to the close of registration on Wednesday. If you bring a different car than you have classified, and it’s in a different class, you will be placed in the non-compete class for the event.
