Clubsport Challenge

Introduction

The Clubsport Challenge is a year-long, 10-race series that ties into the PCA Club Racing calendar. To provide a true comparison of driver skill in a single-car class, the Porsche 718 Cayman GT4 Clubsport will be used with a fixed setup.

Races will be roughly once a month on Sundays starting at 12:00 PM Eastern/9:00 AM Pacific. Races will precede the real-life PCA Club Racing races by 1-2 weeks. The schedule will be coordinated to avoid TRS weekends.

Events generally replicate the racing on a Club Racing weekend by including open qualifying, multiple sprint races, and an enduro.
