Welcome to the Official Spotter Guide for the 2020 IMSA Porsche GT3 Cup Challenge USA by Yokohama. A championship sanctioned by IMSA. The Guide was also commissioned by IMSA,way back before Covid struck. As this is a season long guide, some of the entries may have changed since the enforced break.

The guide will be updated after the revised Road America weekend with some of the remaining liveries.


Thanks to IMSA for partnering with the guide If you get a few seconds, please thank IMSA on Twitter. Without their support, there would be no guide.

NOTE: Please fill free to share the guide on Social Media, but PLEASE LINK TO THIS PAGE and not the guide (as file names change with updates) so your friends and fans can download the latest version of the guide! I can also track data easier which in turn helps my quest for sponsorship
