The 2009 Formula 1 world champion will join regular drivers Tijmen van der Helm and Mike Rockenfeller for the 10-hour Road Atlanta endurance event.
It marks his first prototype race appearance since the 2018 World Endurance Championship round at Shanghai, the last of his four outings in the BR Engineering BR1-AER LMP1 car.
Button, who raced with Rockenfeller in the Garage 56 NASCAR project at Le Mans earlier this year, has made three appearances in the NASCAR Cup Series this year in a Rick Ware Racing Ford.
The Briton remarked that he was “very excited” to be joining the Minnesota-based JDC-Miller team, which won the Sebring 12 Hours with Cadillac in 2021.
The Minnesota squad became the first Porsche LMDh customer to race in IMSA this year, joining the series at Laguna Seca in May after supply chain delays in receiving its hybrid-powered 963. It has managed a best result of fourth at Watkins Glen and Canadian Tire Motorsport Park.
“Whilst I’m having a lot of fun cutting my teeth in the NASCAR Cup series this year, a prototype with high downforce is definitely more in my comfort zone,” said Button.
“That said, the Porsche 963, the IMSA Sportscar Championship, and Road Atlanta are all brand new to me so I can’t wait to tackle all three with my team-mates for the weekend.
“I partnered with ‘Rocky’ at Le Mans this year and he will be invaluable as he’s fantastic at car/team development. He is also incredibly quick which always helps!
“I’ll also have the pleasure of working with rookie Tijmen van der Helm who seems to really be gaining speed and confidence through the season so we should have a lot of fun.”
