PSR was created by Phil Stefanelli, a long-time racer, crew member, engine and chassis builder, and race team owner. Throughout his racing career, Stefanelli wore a variety of hats, exposing him to all the secrets of speed. He has collaborated with industry experts to create some of the most cutting-edge parts and components that have been used to propel drivers to victory lane at all levels of NASCAR, from weekly short tracks to the top levels of the sport. Stefanelli has now coupled his expertise and skills with a bright crew, and ever since then, PSR has become a name in the car industry.
HISTORY OF PSRStefanelli aimed to improve upon existing components by developing his own that were lighter, harder, quicker, and more dependable than anything available at the time. PSR products have risen from these objectives to become a market leader in parts manufacture, chassis construction, and fabrication. And it's all done under one roof in Midland, North Carolina, only a few miles from the heart of stock car racing nation.
Almost immediately, the parts being produced out of PSR's facilities caught the attention of the most astute and quickest teams in motorsports. PSR's components, chassis, bodywork, and configurations have earned victories at tracks around the country. While the PSR team is proud of their past and current successes, they are always working to improve those parts in the future.
