Pre-Entry – Enter Before the Cut-Off and Save!
The definition of a “PRE-ENTRY” is an entry received, with payment, at the ProKart Challenge office by midnight on the Wednesday prior to the event, and will qualify for the pre-entry pricing. Entries after this cut-off will have to be submitted at the event (starting Friday morning) at walk-up pricing. See pricing below. All race pre-entries will be confirmed via email within 1 business day of receipt at the SKUSA home office. If you do not receive an email confirmation within 24 hours, please call ProKart at 951-491-0808 to confirm that your entry has been received and is in process.

Pre-Entry closes at Midnight on June 25th.  Anyone wanting to register for the race or Friday's practice after that time will have to sign-up at the track on Friday starting at 7:00am or Saturday starting at 6:30am.

Capped Entries - Enter Early - Don’t Miss Out!
All classes will have a maximum amount of 40 entries per race. Entries received after a particular class is filled will be placed on a waiting list and held pending cancellation openings.
