California ProKart Challenge

2023 ProKart Challenge Classes
We are making a change to "105.3 Age Criteria" in the next rulebook update.  It will be 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 detaills.

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 2023 Pro Kart Challenge
  • (1) Set of 2023 PKC Stamped Evinco Race Tires per round allowed, but not required.
