Most street Wilwoods are equipped with the BP-10 pads. Most performance oriented drivers don't like them, and complain about their street performance.

The BP-20's are a huge step up in street performance. The work well in dead cold temps, no noticeable dust, and are very quiet. My favorite street pad.

I run Polymatrix E on the track. Very dusty. And really noisy when hot. But excellent initial bite from first to last lap, very predictable, and easy to modulate. I can easily get 1 1/2 to 2 seasons on a set.

You don't need to resurface the rotors when going from BP-10 to BP-20. But you do need to do that if switching to a Polymatrix pad, or any non-Wilwood pad. They don't need to be cut, just resurfaced to get the old pad material off.

I use Hawk HP+ on my BDR with BMW power brakes. They are also very good. Slight dust, quiet, and easy to modulate.
