SpeedKore Performance Group is a Wisconsin-based motor vehicle manufacturer focused on high-performance cars and advanced composite components. The company develops vehicles from concept to completion, using autoclave-prepreg carbon fiber to reduce weight while enabling powerful engine integration, and it offers carbon fiber parts as upgrades for existing vehicles. It emphasizes bespoke, one-of-a-kind builds rather than mass production. Based in Grafton, the firm operates with a small, specialized team and was founded by Jim Kacmarcik and lead builder Dave Salvaggio, with industry veteran Sean Smith serving as lead designer. In addition to its automotive work, SpeedKore pursues licensed partnerships and product extensions, including a 2023 launch of hand-crafted carbon-fiber accessories for motorcycles.
