Gruppe5 Motorsport, Founder
Founded by entrepreneur and lifelong BMW enthusiast, Tom Zajac, Gruppe5 Motorsport is an American automotive company that transforms clients’ (1968-1972) BMW 2002s into hand-built, street-legal racecars.
Tom’s first new car was a 1972 BMW 2002tii. When the factory warranty expired, he found an experienced mechanic who introduced him to Showroom Stock racing. With a few upgrades, a basic roll cage, and fresh brake pads for the track, his 2002tii served as a daily driver and weekend warrior. The car's dual purpose inspired the creation of the Gruppe5 2002.
