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).
