The story
Tec-Mec used an improved, lightened version of the Maserati 250F, named the F415. The car was upgraded by the 250F's designer, Colotti, and financed by Lloyd Casner of Camoradi International. The F415 featured a lightweight space-frame chassis, with the de Dion rear axle set-up was replaced by an independent system using a transverse leaf spring and wishbones. The drum brakes were replaced by Girling disc brakes.
The team made its single outing in the 1959 United States Grand Prix, but the car, driven by Fritz d'Orey lasted six laps before retiring, having qualified 17th on the grid ahead of only the midget racer of Rodger Ward.
Colotti sold the design studio at the end of the year to found Colotti Trasmissioni, and the company continued to produce cars for the Formula Junior series.
The Tec-Mec F415 is still currently used in historic racing, winning the Historic Grand Prix of Monaco in 2016 and 2018.
