California ProKart Challenge

2024 ProKart Challenge Classes (Tentative)
We have made a recent change to "105.3 Age Criteria" in the SKUSA rulebook. It has been adjusted as follows:
A driver’s ‘racing age’ is their age on Jan 1. If they will become eligible for the next higher class in the same calendar year, they may ‘move-up’ at any time during the season.
Please note that once a driver moves up, they cannot move back down. See 105.3.1 for more details.

We reserve the right to make additional modifications to our rules as experience dictates. The ProKart Challenge offers a broad spectrum of classes that provide a place to race for drivers of all skill levels and racing experience. The impetus of the series is to offer a friendly environment where anyone can race with virtually any modern kart package.

Notes

  • Push back bumper will not be required for any classes of the 2024 Pro Kart Challenge
  • (1) Set of 2024 PKC Stamped Evinco Race Tires per round allowed. New tires are recommended for each round, but not required (used tires ok if they have 2023 PKC stamp).
