It has been a quiet three months since the checkered flag flew in St. Petersburg, but it’s finally time for the Whelen Mazda MX-5 Cup presented by Michelin to return to the racetrack for Rounds 5 and 6 this weekend. The setting is Mid-Ohio Sports Car Course, which never fails to produce some of the best racing of the season. A field of 39 cars is expected, including a few new faces that could shake up the championship.
