Dusting?
Do they bite well?
Noisy?
Thanks!

The HP Plus is a good track pad but may a little much if your not on the track alot. The HPS pad is great for Hi-Po street use it is low dust super easy on rotors and lasts for ever. Not as aggressive a bit as the HP Plus, but the Hawk Blue compound is awesome for racing , unbelieveable bite. Whole Hawk line of pads can't be beat, there inexpensive too. Hawk is one of the few people that make Hi-Po rears pads for Audi as well. Anymore questions write me...
