best roadbased pad ( ie good cold bite , kind to discs , reasonable wear , no or little fade ) would have to be Pagid rs4-2's ( blue ones ).
I have not tried too many but the pagids are good for me.
Ferodo 2500 or 3000 are also supposed to work.
Ultimately you get exactly what you pay for.
price for pagids are bout $400 an end.
