New brakes + stiffer suspension = $$$$$$
I've just read the monthly Ferrari Newsletter, there is an article about the GTC handling package. The package is now also available as an after market product, which is quite interesting (at least for me).
£16450 as a factory option, later available as an aftermarket upgrade, which I would not expect to cost ... less.
Price is 22.620 Euro over here. GTC package features carbo-ceramic-brakes, sportsexhaust, carbon interior, larger tyres and different rims (19"), stiffer and lowered suspension.
