As this is the final guide of the 2015 IMSA Season, I would like to say particular thanks to IMSA for partnering with the guide, and making it an official product for the sixth year.

If you get a few seconds, please thank IMSA on Twitter. Without their support, there would be no guide.

Massive thanks to the tens of thousands who have downloaded the guide or picked up one of the printed guides (image below) at the circuit. On average 15000 of these are printed for each race, so appreciate your continued support with this and the other Spotter Guides (remember WEC and ELMS championships continue).

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

Special thanks to all the teams who have helped with the guide this year. EVERY SINGLE TUDOR team and the majority of Continental Challenge teams helped directly in 2015. Thank you!


This race also sees a number of ‘Andy Blackmore Design’ liveries racing. including  the TUDOR series, the #97 Turner Motorsports BMW Z4 ain the TUDOR series while in the Continental series, I designed the  #5 CJ Wilson Mazda MX-5 while their second entry is also based upon my design. The  (#81,#84) BimmerWorld and (#74,#75) and Compass 360 Audi S3 liveries are also my designs.

You can find out more about my liveries at Andy Blackmore Design.

In honour of Justin Wilson, the decal I designed initially for Marshall Pruett which has since been used worldwide is included in this Spotter Guide. Please consider making a donation to the Wilson Children’s Fund or purchasing a sticker or shirt from INDYCAR.com or other outlets.
