Alfa Romeo 4C vs. Porsche 996 GT3 at Brands Hatch GP circuit

Having fun following a 996 GT3 through the traffic at Brands Hatch GP circuit and both cars are pretty evenly matched. Horrible grinding sound is from my rear brakes (or lack of).

4C has rear brakes? I don't think mine does. :-)
Nice job! Is the Alfa modded?
