Welcome to the 12th season of the official IMSA Spotter Guide.

Round five of the series takes place at the Chevrolet Detroit Grand Prix in Belle Isle. Prototype and GTD classes compete, while the GTLM teams focus on Le Mans Test Day.

As with previous years, the guide will be updated during race week with driver changes and any significant livery updates. This is the dedicated page for the IMSA Spotter Guides during 2018 and the url will not change.

If you are at the event, Andy Blackmore Design and IMSA co-produce a Viewing guide which includes a printed Spotter Guides which is normally available in the IMSA FanZone area from Thursday of race week.

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. hank you to all the teams who have helped with creating the guide. Virtually every team assisted in some way this year, so huge thanks!

Massive thanks to the tens of thousands who have downloaded the guide or picked up one of the printed guides at the circuit.

Also thanks to the media outlets which promote the guides including Radio Show Limited, IMSA Radio, DailySportscar and Sportscar365.


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, 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
