Map And Directions ( Google Maps )

Overnight Parking and Camping
PKC has arranged for overnight parking of trailers, as well as overnight camping on site, starting Thursday afternoon, February 9th. Each reserved pit spot is $35; if you are camping overnight the spot is $50 as a flat fee for up to 3 total nights. If you wish to reserve a pit spot for your trailer, purchase it here. For an RV pit spot or camping for your toy hauler, purchase it here. Be sure to list your top 3 choices for each pit or camping spot.  We will contact you to confirm your reservations and add you to the map.

Fuel and Oil Sold at Track
Buttonwillow Raceway will have the spec fuel and oil for sale at our event. Call 661-764-5333 or email This e-mail address is being protected from spambots. You need JavaScript enabled to view it for more info or if you’d like to pre-order 1 liter bottles of Motul 2T Grand Prix and/or 5-gallon cans of C12. Pre-orders are optional.

Pit Vehicles
Although PKC prefers to disallow the use of motorized vehicles in order to avoid unnecessary accidents in the pits, this facility does allow motorized vehicles on their premises. However, PKC reserves the right to confiscate any vehicles, motorized or otherwise, that are being unsafely used anywhere on the kart track premises.
 
Pets On Premises
Dogs are allowed on the kart track premises, but must be kept on a leash at all times. No dogs allowed on grid. Please pick up after your pet.

Air Boxes and Silencers
For all motos, the silencer is open spec and air boxes are not required at this event.

Reserved and Unreserved Pit Spaces
An unreserved pit space is included at no charge with your race entry. However, the location of unreserved spaces is determined on a first arrive, first serve basis with no ability to choose a location or pit neighbor. As a result, you could arrive at “dark-30″ on Friday morning and still be a football field from the pre-grid or worse yet, you can’t get to the event until Saturday. Therefore, we have provided the ability to pre-reserve a pit space(s). In this manner, you choose the space you want now and that space will be available whenever you arrive. There is labor required to administrate pit space reservations, so a cost is involved. However, you will hopefully view the nominal $35/space charge as well worth it.
 
Reservation Instructions
Team Managers with block requests or those that need an irregular sized pit space, should call (951) 491-0808 or email This e-mail address is being protected from spambots. You need JavaScript enabled to view it .
Reserve your Pit Space now in the Online Store

Spectator Tickets
1 and 2 day spectator passes are available through EventBrite and directly on the Spectator Pass page for this event. These passes include pit access, thus enriching the spectator experience through up close contact with the drivers and crew. Prices are $15 for a 1-day pass and $25 for a 2-day pass. Kids 5 and under are FREE, but everyone must sign an insurance waiver.

NOTE: The Buttonwillow facility charges ALL attendees (drivers, crew, team owners, and spectators) a $10 GATE FEE at the front entrance to the property. This is in addition to the Pit Pass charges that PKC requires for their insurance at the kart track. Please inform your guests that they will have to pay a total of $25 for entrance to this event if arriving on Saturday, or a total of $35 if they arrive earlier.

Spectator Tickets and Will-Call

As part of an overall effort to expedite driver check-in, we have eliminated the use of "Will Call" lists, although purchasing your tickets via EventBrite below serves the same purpose. A few things will help us help you.
  • If you know the name of your guest, include it on the ticket. Adding their email address will even send a copy directly to them.
  • If you don't know the name of your guest that's ok too, but you must send them a copy of their ticket, even a screenshot of the barcode via text will work.
  • We can check someone in manually, but verification could delay their entry so make every attempt to provide them with their ticket.

Parents, Guardians and Team Principles

If you need to check in a driver for age or language reasons, you can still purcahse a ticket below to be used at Driver Registration, but please keep the non-drivers to a minimum so we don't bog their line down.
