2026 K1 April 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.

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 lengthily 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.

Teams who are attending the PKC event may begin moving in Thursday, April 23rd at 7:30 am.
K-1 may advertise additional practice days, contact the track at (951) 686-0485 for information on days, times and additional fees.
Our online store page allows you the option of purchasing pit spaces for the PKC event (100.00 per space).
