Following the post-race impounding of Pro Mazda cars 8, 23 and 82 immediately after Sunday’s Cooper Tires Grand Prix of Mid-Ohio Presented by Allied Building Products, series officials have determined that no illegal components, unauthorized parts or other items that would fall outside of the series technical regulations were in use. This process not only included a complete mechanical inspection and review of the vehicles but also inspection and analysis of aero, engine performance, Timing & Scoring data, oils and fuel.
