Hawk HP+ are a terrible street pad. They dust like crazy, they aren't good cold (takes a while for them to get some heat and bite) and they chew up rotors.
The EBC is also a great street pad. Though my favorite combination I had on the car were a set of Axxis Deluxes up front / PosiQuiet's rear. The Deluxes were a decent pad, didn't make any noise and didn't dust much. I've got Axxis Ultimates on the miata, and if you want a more aggressive pad go with that. Excellent bite, great feedback, but they dust a bit more than the Deluxes. You can get them from Pro-Parts-USA (aka TriPoint Motorsports).
