2023 SuperNats XXVI Classes

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

This year the class capacity for all classes will start at 44.  Once a class is sold out, additional drivers will be placed on a waitlist. The first few classes to warrant expansion will open to 88.  THE ONLY WAY TO GUARANTEE YOUR ENTRY IS TO BE IN THE FIRST 44.  We are taking this approach to accommodate shifting demand in some classes and so that we can host as many competitors as possible.

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.

Classes Confirmed for 88

  • Mini Swift
  • KA100 Junior
  • KA100 Senior
  • X30 Senior
  • Pro Shifter

Event Schedule

An event schedule will be released at later date, but it will be similar to years past.  The air cooled classes will run primarily in the morning, and the water cooled classes in the afternoon.

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 This e-mail address is being protected from spambots. You need JavaScript enabled to view it or fax it to 1-951-491-0809. Your entry will be placed on hold and not processed without it.
