IMSA Michelin Pilot Challenge will feature its largest grid since the season-opener at Daytona for Friday’s season-ending Fox Factory 120 at Michelin Raceway Road Atlanta.
The 40-car entry for GS and TCR competitors features a number of additions since the most recent round at Virginia International Raceway including the return of defending series champions KohR Motorsports and an additional Toyota GR Supra GT4 on the grid.
Dean Martin and reigning GS class champion Kyle Marcelli will team up in KohR’s Ford Mustang GT4, which hasn’t been present since the four-hour Daytona season opener in January.
Other additions to the 22-car GS category include the series debut of Forbush Performance with Luke Rumburg and Tom Long at the wheel of its Toyota, ahead of a two-car full season campaign in 2022.
Pierre Kleinubing, meanwhile, is set for his second start of the season in the No. 14 Riley Motorsports Toyota alongside co-driver Alfredo Najri.
Goldcrest Motorsports, meanwhile, has entered a Porsche 718 Cayman GT4 Clubsport for Wesley Slimp and Tyler Hoffman, while NTE Sport will field an Audi R8 LMS GT4 with drivers Jean-Francois Brunot and Kerong Li.
Of note, FCP Euro’s Mercedes-AMG GT4 is absent from the GS class field for the season finale.
The 18-car TCR class includes the return of the No. 81 CB Motorsports Hyundai Veloster N TCR for Caleb Bacon and Coby Shield, Audi RS 3 LMS TCR cars from AOA Racing and TWOth AUtosport/Bestline Auto Tech.
Atlanta Speedwerks has both of its Honda Civic Type-R TCRs entered, with Ryan Eversley currently listed in the two entries, with Todd Lamb (No. 84) and Tyler Stone (No. 94) as co-drivers.
Turner, Wright Set for GS Championship Showdown
Turner Motorsports’ Bill Auberlen and Dillon Machavern head into the title-decider with a narrow 30-point lead over the Wright Porsche of Jan Helyen, who will again be joined by Ryan Hardwick at the wheel.
Robby Foley and Vinny Barletta still hold a mathematical chance of the GS title as well, with the No. 96 Turner BMW M4 GT4 duo sitting 140 points behind in third.
In TCR, Michael Lewis and Taylor Hagler enjoy a 230-point lead and will only need to start the race in order to be crowned class champions.
Track action gets underway on Wednesday afternoon with qualifying on Thursday and the two-hour race getting the green flag Friday at 1:10 p.m. ET with live coverage on Trackpass on NBC Sports Gold and IMSA Radio.
