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.
