Hi Ion,
I used Porterfield R4 pads and Carbotech Panther XP's on the stock rotors. One cool thing about a 2nd set of rotors is you can swap rotors & pads for track use and not worry about different pad compounds on the same rotor or turning the rotor for each pad change.
I installed the rotor according to the supplied instructions: the vents pointing back at the top of the rotor.
Thanks,
Russ
