SKUSA Pro Tour

National Pro Shifter Class to Become KZ Only (Effective Immediately)
Thursday, 18 May 2023 11:20
SuperKarts! USA has determined that at the current time, it would be best for the Pro Shifter class to move forward without the SSE at the Pro Tour or Winter Series. The Master Shifter class will remain mixed, as will SKUSA Mexico and our regional series.
