If the handling of the Zonda in the game is anything like it is in real life, I imagine that this conversation took place at Pagani:
"So, brakes then. What do you think for the pads? Ferodo? Brembo?"
"Nah! Let's make our own!"
"OK then, what are brake pads made of?"
"Erm... bars of soap? Would that work?"
<<shrugs>> "Worth a try."
That thing is fast, and with a bit of suspension tweaking corners well, but it's all a bit pointless when you have to brake for corners three days in advance. I've even tried dropping F1 brakes into it, and guess what? It *still* brakes like a cow!
