Underground Racing is the work of KC Howeth (left), his brother Kevin (right), and their nine-man staff working across a 5,000 sq ft fabrication/dyno shop and a 6,500 sq ft installation facility in Charlotte, North Carolina. The Texas natives were raised on American muscle by a family of stock-car and drag racers. They moved to Charlotte in 1989, where Kevin began to buy, tune and sell Ford Mustangs while working in the family construction business.

The Howeths quickly developed a reputation for supercharging Saleen Mustangs in their spare time before opening a shop in 2003 and expanding their resume to include over 100 Dodge Viper builds. Underground Racing has proven their ability to out perform the competition by winning repeatedly at the V-10 Viper Nationals. Two years ago, a customer asked them to modify his Lamborghini, leading to Bugatti Veyron power and performance at a fraction of the price. Lambo business now dominates their original garage.
