My favorite pad is
Porterfield Racing R4-S compound(pdf).
"the R4-S compound giving a friction level up to .41"..."they will
give you an impressive increase in stopping ability with very minimum amount of pedal effort"..."is also rotor friendly'..."the R4-S compound has the absolute lowest
noise and dust levels possible".
A little pricey but worth it in my opinion. I do have to say that sometimes using their online search tool it doesn't always find the part number. But every time that happens I call them and they provide the part number and I place the order on the phone.
