The F430 GT3 was developed in 2006 by JMB Racing on the basis of the F430 Challenge for the FIA GT3 European Championship as well as national series such as British GT and FFSA GT. It featured revised aerodynamics and higher output, with the 4.3-liter V8 delivering 550 hp. However, due to GT3 regulations mandating a power-to-weight ratio of roughly 2.6 kg per hp, the car weighed 1219 kg in race trim—approximately 119 kg more than the GT2 version. At the 2007 24 Hours of Spa, the quickest GT3 was around 8 seconds per lap slower in qualifying than the GT2.
