In 1995, Ferrari introduced a race-ready F355 Challenge model for use specifically in the Ferrari Challenge race series. The Ferrari F355 Challenge model was developed by starting with a standard Ferrari F355 Berlinetta and modifying it with a US$30,000 factory-to-dealer supplied kit. The initial 1995 cars came with factory fitted cage mounts and without carpets. Each year, the cars arrived with more and more factory fitted race parts, culminating in 1998 with full-evolution cars which were supplied as virtually complete race cars except for some parts such as the rear wing, which still needed to be fitted by the dealer.
