Billy Johnson and Bob Michaelian will return to the wheel of the No. 59 KohR Motorsports Ford Mustang GT4 in IMSA Michelin Pilot Challenge next year, it has been announced.

The pairing, who closed out the recent season with two podiums and five top-ten finishes, will continue as a driving duo next year.

Michaelian is set for his fifth consecutive season with the Dean Martin-led squad, while Johnson is back for a second straight run with the Florida-based team, having also taken part in previous seasons with KohR.

They join the all-new pairing of Evan Slater and Ray Mason in the team’s No. 60 entry, which will sport a Greg Biffle tribute livery for next month’s four-hour season-opening BMW Endurance Challenge at Daytona International Speedway.

With 24 GS wins, former Ford factory driver Johnson is tied with Matt Plumb for the most victories in the series heading into the 2026 season, which kicks off at Daytona on Jan. 23.
