Ryan - you are right that the car is more road use than track. But i do feel i need some extra braking power with 280 horses under the bonnet.
Buying new Tarox discs and pads is not such a hassle, since i buy them new (only they'll be a bit pricey).
The big problem are the bigger kits, especially kits which include used calipers.
I am checking some prices for EBC red stuff and Tarox disc. I'll update once i get them and see if the noise gets lower.
