2021 Official IMSA Spotter Guide

Latest Guide: 2021 Mobil 1 Twelve hours of Sebring
Latest update:  v1d -Friday March 19th, 08:.30 EST

Welcome to the home of the Official 2021 IMSA Spotter Guide series. This page will be updated throughout the season,  prior to each event in the 2021 MSA WeatherTech SportsCar Championship and IMSA Michelin Pilot SportsCar Challenge series.

Version 1 of the 2021 Twelve Hours of Sebring guide (link) has already been updated with the latest livery and driver changes (see below) and feature all the entries in both series across three pages. If you are attending the race, a printed booklet will be available at the circuit.


Thanks to IMSA for partnering with the guide. If you have found the guide useful, please feel free to thank IMSA on Twitter. Without their support, there would be no guide. Thanks to all the teams who have helped with creating the guide.

Almost every team assisted again during this very challenging year! Also, special thanks to Shea Adam and Paul Marquardt for their awesome proof-reading skills for this initial guide.

Thank you to the fans, corner workers and media who have continued to support the Spotter Guides over the years. Your support, particularly this year has been massively appreciated.


NOTE: Please feel free to share the guide on Social Media, but PLEASE LINK TO THIS PAGE and not the guide (as file names change with updates, particularly with the month change this week) 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
