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 before 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 PKC/SKUSA home office.  If you do not receive an email confirmation within 24 hours, please call 951-491-0808 to confirm that your entry has been received and is in process.

Pre-Entry closes at Midnight on Wed, May 16th.  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.
