California ProKart Challenge

2022 CalSpeed Oct Pit Spot Reservations
Due to the size of this event and the unique variety of pit/camping spot dimensions available, you will be submitting your detailed pit/camping request in writing via email instead of directly purchasing the space you need thru the SKUSA STORE. We will place you on the map and then invoice you, so you will need to be exact in your emailed request. Be sure to READ ALL DIRECTIONS BELOW and then look at the attached pit map for those details. SKUSA has no option but to round up to the next space for those who have irregular space requests.

If you know EXACTLY how much space you will need for your pit and/or camping spots, please EMAIL a complete drawing (as a PDF -- no JPG phone pictures, please) to This e-mail address is being protected from spambots. You need JavaScript enabled to view it ASAP. Please put your team name in the subject line.

Emailed requests will be replied to with a confirmation upon receipt. Incomplete requests will be rejected and/or disregarded until complete.

NOTE: The PKC event and class sponsors will receive priority pit spot placement, so be sure to put a reminder note on your pit request if you are a PKC sponsor. LAKC RESERVED PIT SPOTS DO NOT APPLY TO THIS EVENT, although we will do our best to accommodate your desired location(s).

Camping, RV and Pit Spot Pricing:

  • First 6 rows (BLUE NUMBERS) -- $50 per space
  • Next 3 rows (RED NUMBERS) -- $45 per space
  • All others pit spots (BLACK NUMBERS) -- $40 per space
  • Toy Hauler camping in Pits -- add $100 fee plus the price of the pit space (Please add the note to your pit request that you will be camping overnight in your pit.)

You need JavaScript enabled to view it that you would like to reserve an RV spot, along with your top 3 preferred locations. We will be in touch to confirm the location and invoice for payment.

Just present the proper credentials (Driver’s license, proof of insurance and handicapped placard) at Registration to receive an event-specific pass (which must be attached in plain sight to avoid confiscation of the prohibited vehicles until the conclusion of the event).
