Ferrari 575 GTC
The company developed a new GTC handling package and Superamerica version (a limited run of 559 Retractable hardtop variants of the coupe), along with raising the power from 515 PS (379 kW; 508 hp) to 540 PS (400 kW; 530 hp).
The GTC package includes Ferrari's fourth Carbon fibre-reinforced Silicon Carbide (C/SiC) composite ceramic composite brake system, made by Brembo (the first 3 being featured on the Challenge Stradale, F430 and Enzo) as well as a more performance-tuned suspension system, low-restriction exhaust system, and unique 19 inch wheels. The new brakes are based on the company's Formula One technology. They use 15.7 in discs with six-piston calipers in front and 14.2 in discs with four-piston calipers in the rear.
