Class Structure
This year’s event schedule promises to deliver the usual abundant track time – including opportunity for drivers to run multiple classes – with breaks in between. The classes are detailed below.
Capped Entries
To provide maximum track time for every participant, we will be capping the amount of competitors per class at 88 or 44 as follows:
-
88 for KA100 Junior, KA100 Senior, X30 Senior, and Pro Shifter
-
44 for All other Classes
SKUSA reserves the right to adjust the entry cap per class at any time, based on entry counts and class demand. The format of limiting entries and classes provides 5 days of virtually non-stop racing action. To quote Steve McQueen, "Racing is life. Anything that happens before or after is just waiting." To ensure your spot in this year’s event, enter early or you may miss out.
Need Proof of Driver Age
All Drivers must assure that their date of birth has been verified by SKUSA with a Birth Certificate, current passport, government ID or driver's license at time of Online Registration. If it has not, email it to

or fax it to 1-951-491-0809. Your entry will be placed on hold and not processed without it.
According to the SKUSA Rulebook, the driver's racing age for purposes of class eligibility is based on the age attained by the last day of the racing year. SKUSA reserves the right to advance, as well as limit advancement of, any competitor found to be outside of the ‘performance envelope’ for the class. See SKUSA Rulebook Section 105.
