Championship Points System

Points are calculated based on your finishes in the Heats and Main. There are also bonus points for Pole and the fastest lap during the Main. There is (1) race drop for the 2025 PKC (6) race season to calculate the final championship points. For more information please see the Points System page.  

RULES REMINDER: Regardless of the number of laps completed, any driver that does not weigh in with their kart at the scales at the end of each on-track session (after taking the green flag) will be disqualified and will not be eligible for any points for that session.
