Fenhaus's cousin, father, and grandfather raced snowmobiles on ice oval tracks, and he started his racing career by racing snowmobiles before racing on pavement.[1] He was inspired by driversTim Sauter (from watching him race at State Park Speedway) andKevin Harvick (which is why he chose to race the No. 4 in late models and uses the same font that Harvick does in the Cup Series).[1]
In 2022, Fenhaus graduated early fromWausau East High School and moved from Wisconsin to North Carolina (where NASCAR teams are located).[2]
