Risi Competizione

Risi Competizione was initially created as a competition arm of Ferrari of Houston, a car dealership owned by Giuseppe Risi. Doyle Racing, wishing to replace their outdated Riley & Scott sports prototype, was able to use Risi's connection to Ferrari to purchase two new Ferrari 333 SPs. Risi in turn was able to promote his Houston dealership. The first of the team's 333 SPs was planned for use in the IMSA GT Championship, while the second was kept in Europe to prepare for the 24 Hours of Le Mans, to which the team had already been invited due to the success of Doyle Racing the previous year in IMSA.

Under the Maserati Corse name, Risi ran a Maserati MC12 in the GT1 class of the American Le Mans Series.
The new partnership was able to quickly find success as the team won in only the second race of the season, drivers Wayne Taylor and Eric van de Poele earning victory at Las Vegas Motor Speedway. In Europe for Le Mans, Taylor and Van de Poele were joined by Fermín Vélez, and although they were unable to win the race overall, they scored victory in their class with an eighth-place finish. Back in the United States, Doyle-Risi earned their third victory of the year at the inaugural Petit Le Mans at Road Atlanta, winning the race overall against several teams they had competed against at Le Mans. With two victories for the year, Doyle-Risi won the team championship for the World Sports Car class, while Taylor was second and Van de Poele third in the drivers' championship.

Doyle-Risi opened the 1999 season by competing in the 24 Hours of Daytona, finishing the race in second place and only two laps behind the race winner. Doyle-Risi followed this by joining the American Le Mans Series, a replacement for the previous year's IMSA GT Championship. Both of their 333 SPs were entered for the full season. However, facing stiffer competition from Audi, BMW and Panoz, the team was unable to score any victories over the year, although they did score a season-best result of fourth at the Grand Prix of Atlanta. The team finished the season fourth in the LMP championship.
Giuseppe Risi took full control of the team in 2000, rebranding it as Risi Competizione, and retained one of the 333 SPs from Doyle. Ralf Kelleners and Mimmo Schiattarella were signed, and Risi moved to the new Rolex Sports Car Series. The team earned two second-place finishes and scored fourth in the team championship. Schiattarella earned fourth in the drivers' championship, while Kelleners was sixth. In 2001, Risi entered a sole 333 SP at the 24 Hours of Daytona but failed to finish, and the team chose to not compete for the rest of the season.

During Risi's year away from competition, the company began development work on a competition version of the 360 Modena for Ferrari. Although busy with development, Risi agreed to a partnership with Rand Racing to run a pair of Nissan-powered Lola B2K/40 prototypes in the SRPII class of the Rolex Sports Car Series in 2002. The Rand-Risi team swept the ten-race season, winning their class in every event and clinching the championships. Meanwhile, Risi's 360 debuted in two of the final rounds of the American Le Mans Series season, earning podiums in their class for both races.
For 2003, Risi's 360 was entered in the Daytona 24 Hours and earned second place overall, beating multiple faster prototypes. The team then moved permanently to the American Le Mans Series, running a pair of the new 360s. The team earned second place in their class championship, while Risi Competizione also returned to the 24 Hours of Le Mans for the first time since their 1998 victory, finishing in 27th place. Risi continued their development of the 360 Modena into 2004, eventually upsetting the series' Porsche dominance with a victory in their class at the New England Grand Prix. Difficulties in completing races, however, led the team to eventually finish the year fifth i
