The term "Donk" refers to 1971-76 Chevrolet Caprice or Chevrolet Impala cars. When it comes to "Donk Racing" these are show-quality classic cars with big wheels that compete on the drag strip. Born in Savannah, GA and bred in Hardeeville and Orangeburg South Carolina, Sage Thomas is better known by his nickname "Donkmaster" given to him by a nine year old fan. Thomas spent most of his days as a youth shadowing his Uncle Buggy who instilled in him a love for racing competition and an understanding of hard work. Thomas built his first "Donk" at the age of 16. Through a DVD he was introduced to the big wheel racing culture in Florida. This led Thomas to create the National Donk Racing Association (NDRA) Thomas created an organization that was a scalable championship series for the world he loves. The NDRA is the world’s first sanctioning body for big wheel racing with a standard structured rule set and a point system for Big Wheel Racing, just like other racing organizations.
