With MSR's move to the DPi class for 2021, Farnbacher found himself initially without a ride. In January, however, it was announced that he would compete with Magnus Racing in their new Acura NSX GT3 at the 24 Hours of Daytona.[6] For the remainder of the WeatherTech Sprint Cup, beginning at Mid-Ohio, he joined Compass Racing, driving alongside Jeff Kingsley.[7] Following an injury suffered by Marc Miller prior to the round at VIR, Farnbacher also competed with Gradient Racing, finishing 15th in the GTD class following an accident.[8]
For the 2022 IMSA SportsCar Championship season, Farnbacher embarked upon a Michelin Endurance Cup-only campaign with Gradient Racing,[9] alongside a full-season effort in the GT World Challenge America with HPD Academy graduate Ashton Harrison.[10] Following a second-place finish at the Indianapolis 8 Hour, the duo claimed the Pro-Am class title.[11]
Farnbacher began 2023 by taking part in the Michelin Pilot Challenge event at Daytona, driving for HART. It was his first time piloting a TCR touring car.[12] The remainder of Farnbacher's season involved a second season in the GT World Challenge America alongside Harrison, this time in the Pro class.[13]
