I havent had a chance to check my local auto parts store, but your post doesnt make it look very promising for me. I am also not running with them at the moment, and have EBC Green Stuff pads and I am experiencing a ton of noise coming from my brakes, both in stopping scenarios and normal driving. Very annoying to say, pull through a drive through, and the noise bounces of the wall. I can only imagine what a car next to me on the road hears. Your sig say's full EBC brakes, so I wonder if you have the same issue or not.
Anyway, Im still looking for a way to get these, if I find a way Ill be sure to post here.
