Team TGM will make the switch from Mercedes-AMG GT4 to Chevrolet Camaro GT4.Rs in IMSA Michelin Pilot Challenge next year, with Matt Plumb joining his brother in the two-car operation.

The 2018 GS class championship-winning team will field the Pratt & Miller-built Camaro GT4 full-time, with team owner Ted Giovanis joined by Owen Trinkler, who moves from the No. 46 entry he shared with Hugh Plumb.

Hugh Plumb, meanwhile, will team up with his brother Matt in the second Camaro GT4.

It comes following longtime TGM driver Guy Cosmo’s exit from the team, which he announced following October’s season-ending round at Michelin Raceway Road Atlanta.

The Florida-based team claimed only a single victory, at Lime Rock Park, this year, although has retained longtime strategist Joe Varde and most of the operation.

“We’re making some changes, all for the positive, but we’re up for the challenge,” Giovanis said.

“We already have the cars and have already tested the cars. We’re excited to move forward with them in 2020 and have a full testing plan put forth.

“Owen tells me I’m going to be a lot better in this car than other cars I’ve driven. That remains to be seen. There was some indications at our test this is going to be true.”

Trinkler added: “We’ve won a championship in another platform and I feel we can do this with the Chevrolet Camaro. We’re going to be really strong this year.”

The Plumb brothers, meanwhile, last raced as co-drivers with Rum Bum Racing, which ceased operations following the second round of the 2016 season.

“Driving with my brother, I’ve had a lot of success in the past,” Hugh Plumb said. “We’re still able to sit around the Thanksgiving table.

“We’re very competitive against each other. It makes for a great pairing. For me it’s great to be back with TGM and Chevy.”
