Tom Herb and Ryan Dalziel Co-Drive Fall-Line Motorsports 2017 No. 16 Mercedes-AMG GT3 to Smooth Run Group C Win at the 12 Hours of Sebring.

The HSR Classic 12 Hours of Sebring International Raceway is always a difficult race. Not only for the cars but the drivers as well. Bumpy track conditions and the infamous setting sun make the 2021 race a real challenge. Run Group C emerged into a GT Modern (GTM) battle that was ultimately won by the 2017 No. 16 Fall-Line Mercedes-AMG GT3 of Tom Herb and Ryan Dalziel.

Herb and Dalziel went back and forth with the TAG 2016 No. 991 Porsche 991 GT3 of Thomas Gruber throughout the race. Gruber won both opening rounds in his Speed Syndicate-prepared 991 but could never quite shake the Mercedes-AMG GT3 that trailed just seconds behind in both races.

Herb and Dalziel co-drove to Saturday night’s round three victory that, along with a spin by Gruber, allowed them to build a nearly 45-second overall lead heading into Sunday afternoon’s fourth and final race.

Gruber picked up his third victory in the finale, but Dalziel once again was content to cruise just behind in second and defend the No. 16 team’s overall lead with a competitive but controlled pace. The Mercedes-AMG GT3 crossed the finish line just 0.671 of a second behind the Porsche to seal the overall win with a comfortable 43-second margin of victory.
