Hot day at Road America.
Kevin Buckler pitted on lap 23 due to problems with his cool shirt device.
Driver change to Michael Schrom
Kevin Buckler– "After 20 minutes of standing in front of the car for the opening race ceremonies, I realized just how warm it is out there today. I jumped into the car and needed the cool suit toward the beginning of my stint. I turned it on and it wasn’t working. I stayed out as long as I could and just had to come in, I was beginning to not be able to see."
Track conditions are greasy and the soft compound tires were changed to medium-medium compound.
