After doing more research into "Posi-quiet" pads they are actually really made by Axxis so they are very good. they are basically the Axxis super-duty deluxe pads (step under the Ultimates) and they dust very little and as the name suggest they never make alot of noise. They also have a wide temperature range so its good multi-purpose street/track pad. However be forwarned.... Cross drilled rotors + track = BAD news unless its an OEM cast cross drilled design (aka Porsche or new MBs).
