SERIES SPECIFIC RULES FOR THE 2017 ProKart Challenge
Competitors should download the 2017 SuperKarts! USA Rules and Regulations . All rule book amendments, changes and clarifications will be posted here.


Race Numbers

You will be assigned your unique and official kart number (with regional letter designator) when you purchase or renew your SKUSA membership and/or register for your first race of the season. This number/letter combo is required on all 4 sides of your kart for all competition sessions. NOTE: The qualifying 2016 PKC class champions (as listed here) have the option of running their earned championship single-digit race number (with letter designator) if running in the same class this season.  SKUSA's National Number plate winners -- 1st thru 3rd from the 2016 Pro Tour -- may race with their national number plates as well in 2017 (as approved by SKUSA). If you are new to SKUSA, you will be asked to provide 3 choices of a race number with the application for a SKUSA license.

All competitors in SKUSA events are required to have full width rear protection. See Rulebook section 20.2.4.4.

SKUSA On-board Camera Registration policy

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. Rule 20.2.7.2.2. Identification.

Spec Tires

  • A total of two (2) front and two (2) rear Race Tires are allowed PER RACE DAY. However, a competitor can choose to run the same two (2) front and two (2) rear Race Tires for multiple Race Days.
  • Race Tires are defined as "stamped" spec tires purchased from PKC. To insure availability, Race Tires should be ordered from PKC prior to the Wednesday 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 Mini & Micro Swift. The Evinco “H” Blue tire is the spec Race Tire for Mini & Micro 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 (although the older MG-WZ rain tire will also be allowed). 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 (or MG-WZ) 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 Friday practice days and Saturday race 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 are 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.
  • Effective 1/1/16, practice tires should 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

  • Effective 3/17/16, VP C12 is now the spec fuel that must be used at all PKC events for ALL classes, including X30 and Mini/Micro Swift.
  • Motul 2T Kart Grand Prix is the spec oil.
  • PKC is not providing spec fuel or oil for their events. Competitors are responsible for bringing their own fuel and oil.

Practice and Qualifying -- all classes

  • Transponders are required in all practice and race competition sessions on Saturday – and are now requested by noon on Friday practice days. You will not be allowed on the track Saturday 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 20.3.1.9.3 of the SKUSA 2016 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.
  5. 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 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, the competitor will start the next competition session at the back of the lineup.

Pre-Tech

PKC employs a self-certification form to facilitate pre-tech inspection. The driver initials 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. Click Here to download Pre-Tech Form.

Pit Vehicles, Air Boxes Required, and Pets on Premises

Please refer to the Venue Information page of each event for venue specific rules.
