Push-Back Bumpers

Will NOT be run in any PKC classes for 2020.

Rear Protection

All competitors in SKUSA events are required to have full width rear protection. See Rulebook section

SKUSA On-board Camera Registration policy

See SKUSA Rulebook section All cameras used at SKUSA events must be registered prior to use and have the SKUSA inspection sticker clearly visible on the camera body. See the Tech Director to register your camera. Additionally, each camera must be clearly marked with the owner’s name and mobile phone number. Cameras without identification may not be returned. Loss of the camera on the racing surface may result in penalties, including loss of positions, loss of points, and/or monetary fines. No camera mounting is allowed on or in the driver’s helmet, on the radiator, on a sidepod, or on any part of the driver.

Spec Tires

  • A total of two (2) front and two (2) rear Race Tires are allowed PER RACE. However, a competitor can choose to run the same two (2) front and two (2) rear Race Tires for multiple Races.
  • Race Tires are defined as "stamped" spec tires purchased from PKC. To ensure availability, Race Tires should be ordered from PKC prior to the Monday immediately preceding the event. Race Tires may be ordered for pickup at the event or drop-shipped prior to the event to locations within the continental US.
  • The Evinco “M” Red tire is the spec Race Tire and the only slick that can be used in qualifying, heats, and mains for all classes except X30 Junior, KA100, and Swift classes. The Evinco “H” Blue tire is the spec Race Tire for X30 Junior, KA100, and Swift.
  • In the event that a 'rain race' is declared by the race director, the official spec 'rain' tire is the MG-WT "wet" tire ONLY, and all rain tires must have a readable barcode. If such tires are used during a competition session, they will be marked by the technical officials at the end of the session and will be the only set of rain tires the competitor may use for the balance of the event. Either new or previously used MG-WT rain tires may be utilized, and do not need to be "stamped" by the PKC Tire Desk.
  • The PKC Tire Desk will be open on event days per the posted event schedule. Competitors are required to pick up their set of stamped Race Tires (slicks) during these time periods, unless they were shipped ahead of time (or a previously stamped set of race tires is being re-used). Only Race Tires (slicks) received from the PKC Tire Desk (or stamped race tires drop-shipped by PKC) are eligible for competition at each event.
  • Practice tires must also be the Spec Evinco tires described above. The new spec Evinco tires for use as practice tires can be purchased from PKC/SKUSA or any authorized distributor.

Spec Fuel and Oil

  • VP MS98 is the spec fuel that must be used at all PKC events for ALL classes, including X30, KA100 and Mini/Micro Swift.
  • Elf HTX 909 SAE 50
  • The mandatory ratio of fuel to oil for all IAME classes is 1 gal C12 to 8 oz spec Oil.
  • PKC is not providing spec fuel for their events. Competitors are responsible for bringing their own fuel and oil. In some cases, the track will have the spec fuel/oil available for purchase on site.

Used Tires and Fuel Cans

Unless specifically offered by PKC at this track, these items are NOT to be left on site, and must be taken home by all competitors/teams. Penalties or fines will apply for violators.

Practice and Qualifying -- all classes

  • Transponders are required starting with the 3rd practice session on Saturday – and for the balance of the event. You will not be allowed on the track after this time without a transponder and will be black-flagged if passings are not being registered (consistent with your assigned transponder code) in the T&S system.
  • Anyone who misses their qualifying session or is in the wrong qualifying session will be assigned a “no time” and start at the back of the field in their respective class for their next competition session.

Engine Changes

See section of the SKUSA Rulebook, along with the additional clarifications below:
  1. The engine seal number (received in Registration) shall be entered by each driver on the Pre-Tech Certification form that is turned in prior to the first competition session (i.e., qualifying), and installed on the kart as instructed. This seal must remain in place for the duration of the event. See the event Technical Director for additional assistance.
  2. Engines and/or components may also be "painted" by the event technical staff at the post qualifying weigh-in.
  3. Event technical staff may inspect an engine's seal number and/or "paint" at any time during the event.
  4. Any engine change subsequent to qualifying MUST be pre-approved by the event Tech Director and if not, will result in a DQ and loss of points for ALL prior race sessions and a last place start in the next race session.

    All IAME classes: It is solely the driver's responsibility to solicit and receive an engine change approval form from and executed by the event Tech Director. It is also the driver’s responsibility to demonstrate engine damage in order to get Tech Director Approval to repair or change engines. If the competitor is unable to demonstrate damage, one additional engine (total of 2) may be approved by the event Technical Director. If approved, a 10-position starting penalty will be assessed in the next competition session.

    Stock Honda classes: After qualifying, any repair of controlled components must be approved and recorded in advance by the Technical Director or staff member. Approval must be received prior to disturbing the seal/paint. If approved, a 10-position starting penalty will be assessed in the next competition session.

    NOTE: Repairs are defined as replacing any non-functioning or damaged component including gaskets, seals and O-rings.


PKC employs a self-certification form to facilitate pre-tech inspection, and this form will be provided at Registration. The driver completes and signs the form to certify that the listed items are in compliance. The form is then submitted on the grid for qualifying. Drivers are not allowed out for qualifying without turning in an executed pre-tech form. Spot checks of safety items will be made throughout the event and violations may result in penalty assessments. 

Pit Vehicles, Air Boxes Required, and Pets on Premises

Please refer to the Pit Spot Reservations page of the SKUSA website for each event for venue-specific rules.
