The Ferrari F430 GT3 and F430 Scuderia GT3 - A close look at these Sports cars performance, technical data, features, comparing rivals, history, used prices. The Ferrari F430 Challenge Sports car was launched in 2005, and based on the F430 production car with its weight radically reduced to 1225 kg following an exhaustive schedule of removing all unnecessary items, from fitments to the interior. Only 100 of these cars were built. In 2006, JMB Racing used the F430 Challenge as the basis for development of a special racer designed to be entered in the FIA GT3 European Championship, and British GT Championship. The resulting car, designated the F430 GT3, was superior to the F430 Challenge in terms of more highly developed aerodynamics and increased output, even though both utilised the same 4.3 litre, V8 engine.
