Guido Forti was a racer in the 1960s and early 1970s but then decided to join forces with engineer Paolo Guerci joined forces to run a young Teo Fabi to the Italian Formula Ford 2000. The team was successful and moved up to Formula 3 the following year with Fabi in the Italian and European Formula 3 Championships, with a March-Toyota. The result was several victories in both series and fourth places in both titles. The team enjoyed some success in South American F3 in 1979 with Oscar Larrauri, but while he went to success with Euroracing, Forti stayed in Formula 3 with Dallara chassis with Franco Forini, winning the title finally in 1985. This led to a successful era with titles in 1987-88-89 with Enrico Bertaggia, Emanuele Naspetti and Gianni Morbidelli.
The team tried to break into Formula 3000 in 1987 but did not have the money to run a proper programme for Nicola Larini, but in 1988 the team managed a full season with Bertaggia. The team then decided to switch to Lola chassis and had some success with drivers Claudio Langes and Morbidelli. In 1991 Forti quit Fe to concentrate on Formula 3000 with Naspetti and Fabrizio Giovanardi. This was more successful and Naspetti won four races and was third in the championship. The following year Andrea Montermini finished runner-up in the European F3000 series. It was at the end of 1992 that Forti found a way to fulfil his ambition of getting into Formula 1, by signing up wealthy Brazilian Pedro Diniz for Formula 3000. The team was led that year by Olivier Beretta, but through Diniz, Forti met Carlo Gancia of the celebrated drinks empire. Gancia bought Guerci’s shares in the team and work began on an F1 project, which would be funded by customers of the Diniz supermarket empire, notably Parmalat, Sadia and other Brazilian companies. The team entrusted the design of the Forti FG01/95 to F1 veteran Giorgio Stirano with aerodynamics completed by former Brabham aerodynamicist Hans Fouche in the Aerotek windtunnels in Pretoria, South Africa. Composite work was done by Belco Avia and the cars featured Cosworth engines. Roberto Moreno was signed to drive alongside Diniz in 1995, but the cars were not very competitive and at the end of the year Diniz moved to Ligier. Forti hired Luca Badoer and Montermini and the team found some backing from Replay, TAT, ITS and Elf. Sergio Rinland was named the new technical director and Cesare Fiorio was hired a team manager. With a few weeks the whole operation was falling part and Forti was taken over by an organisation called Shannon Racing, which was in fact owned by Belco-Avia, which was owed money by the team. Forti went to court in Italy to try to regain control of his team but later that year a judged ruled against Forti, although by then it was irrelevant as the team closed down in the midseason. Forti made a brief return to motor racing in a team manager role in Euro F3000 in 2002 and 2003.
