2025 K1 March Pit Spot Reservations

Reserved and Unreserved Pit Spaces - all cost the same!

A pit space is NOT included with your race entry, and whether reserved or unreserved, there will be a cost to everyone to pit at this event no matter what – so we highly encourage all attendees to reserve their pit spots ahead of time. And as usual, PKC Sponsors will be placed on the pit map ahead of non-sponsors. Please read the following carefully, and send an email to This e-mail address is being protected from spambots. You need JavaScript enabled to view it (if you haven’t already) to be added to the distribution list for the 2025 Class Sponsorship information.

Due to the limited amount of pit spaces, a maximum of ONE SPACE per entry has been imposed. Pitting with a team does NOT mean you can purchase a pit space to park your passenger vehicle.

The location of unreserved spaces will be determined on a first-arrived, first-served basis with no ability to choose a location or pit neighbor. As a result, you could arrive before gates open on Wednesday, Thursday or Friday morning and still be a lengthly distance from the pre-grid. Include in your pit spot purchase/reservation your top 3 choices of a pit location and we will do our best to accommodate you. Your assigned space will be available whenever you arrive. There is labor required to manage pit space reservations as well as pitting everyone upon arrival, so a cost is involved. 
  • Pit spaces for this event are $100 per spot, and parking will begin at 8:00 am on Thursday, Feb. 27. 
  • K1 has offered the option to pit earlier – begining at 12 noon on Wednesday – for an additional fee.
  • Teams who are interested need to contact K1 at (951) 686-0485 for additional information and their fee.
  • NOTE: Wednesday arrivals will be placed in the same pit spaces for the entire event weekend.
  • K1 will require your proof of pit purchase receipt from SKUSA prior to allowing entry on Wednesday. Again, PKC Sponsors will have priority pit placement – in the order of the date spaces are purchased. SO RESERVE NOW!
Due to facility regulations, there will be NO OVERNIGHT CAMPING at this event. This includes no sleeping in trailers/toy haulers.

PIT SPOT RESERVATIONS CLOSED. PLEASE SEE REG DESK AT TRACK
