Making its first-ever entry in the top-flight IMSA WeatherTech SportsCar Championship (IWSC), JR III Racing arrived to Road America well prepared—having tested at the track,  a driving roster comprised of podium-winning drivers and a full crew on hand to support the team debut.  Mid-Ohio podium finishers of Terry Olson and Mike Skeen paired up behind the wheel of the No. 30 Jr III Racing Ligier JS P320 as the Charlotte-based team made another progressive step with its WeatherTech debut this weekend.
