The team was established in 1994 and spent its early years in junior single-seater categories in North America. Its first significant success came in the Star Mazda Championship, which the team won in 2007 with American driver Dane Cameron. Further Star Mazda titles followed in 2009 with British driver Adam Christodoulou and in 2011 with Frenchman Tristan Vautier, the latter earning a scholarship into the Road to Indy ladder program. In 2009 the team also claimed the F2000 Championship Series title through Chris Miller, one of the team's co-founders who has remained a driver in the program into the sportscar era.
JDC-Miller made its debut in prototype sports car competition in 2014 when the United SportsCar Championship — formed by the merger of the Rolex Sports Car Series and the American Le Mans Series — provided a new arena for the team. Chris Miller and Stephen Simpson were the primary drivers in that inaugural season, and while results were modest, the team showed steady improvement over the following years.
By 2016, competing under the championship's renamed WeatherTech SportsCar Championship banner, the team achieved its first major victories. It won the 24-hour race at Daytona International Speedway and the Long Beach Street Circuit event in the Prototype Challenge class, finishing third overall in that season's standings with Mikhail Goikhberg and Stephen Simpson sharing the car.
The 2017 season saw JDC-Miller step up to the full Prototype class, where Goikhberg and Simpson continued as the core pairing. The 2018 campaign marked another milestone as the team fielded two full-season entries for the first time, running the No. 85 and No. 99 cars simultaneously. That year Simpson earned the team's first Prototype class victory in the round at Watkins Glen International.
In June 2022, Porsche announced that JDC-Miller MotorSports would become the first customer entrant for the new Porsche 963 LMDh prototype, designed to compete in the GTP class — the top tier of the IMSA WeatherTech SportsCar Championship — from the 2023 season onward. The move represented the most significant technical step in the team's history, aligning it with one of the foremost factory programs in global sportscar racing.
The team's full-time GTP lineup has featured Tijmen van der Helm and Laurin Heinrich in the No. 85 Porsche 963. Alongside the GTP program, JDC-Miller has continued to field a Michelin Pilot Challenge entry — the No. 17 Unitronic/Liqui Moly Porsche 718 Cayman GT4 RS Clubsport — for Chris Miller and Mikey Taylor in the GS class, maintaining the team's tradition of running multiple programs simultaneously.
JDC-Miller MotorSports has built a reputation as a resilient privateer operation capable of competing at the highest levels of North American sportscar racing. From nurturing junior-category talent through the Star Mazda and F2000 championships in the 2000s to campaigning a factory-supported LMDh prototype in the 2020s, the team's trajectory reflects the broader transformation of American endurance racing over those decades. Winning the 2016 Daytona 24 Hours in the Prototype Challenge class remains among the landmark results of its sportscar program, while the step to GTP-class Porsche machinery signaled the team's ambitions at the front of the IMSA grid.
