The Transcendental Racing IMSA GTU 240Z (VIN # HLS30-01543) has been raced consistently for the past fifty years. Against all odds, it powered its way to the 1976 IMSA GTU Championship. Privateer driver, Brad Frisselle, defeated highly-funded factory teams with this amazing piece of machinery that was built by a world class racing team.


In recent years, David Martin raced the Transcendental Racing IMSA GTU 240Z across North America. Martin raced participated in bespoke events across North America such as the Rolex Monterey Motorsports Reunion (Weathertech Raceway at Laguna Seca), Sonoma Speed Festival (Sonoma Raceway), the Mitty (Michelin Raceway Road Atlanta), and the Sommet des Légendes (Le Circuit Mont Tremblant). 

In 2021, David Martin unfortunately passed away due to illness. David was always a kind and generous soul, who's passion for racing history was undeniable. His spirit will live on in the Transcendental Z car.
