- Car/Driver must be registered. The first to register a # will receive that #. Example: A driver wants to register their car #1 and do so, then another driver wants to register their car # also #1, they can’t do that. They will need to add a letter to their # such as 1A or something and it must be marked before the racing events start for proper scoring. We understand being a touring series that there will be same #’s at some point and we will let you know if we already have that driver # registered for that event.
- Please put numbers on the front (headlight area) and rear (taillight area) of your cars to assist the Spotter’s when lining up.. And of course most driver’s know who they were behind in during a race so it will be easier to do quick line ups in the event of a caution.
- Size of #’s : Door #’s should be a minimum of 18” x 5”, Roof should be 24” x 5” and should be put on where the # is vertical to the passenger side of the car and the headlight/tail light #’s should 2” x 6”
