Gave up on carbon ceramic pads for the street. I'd got myself a set of Endless CCX pads for the Evo. Stopped the car remarkably well, but were wayyy too loud around town. Tried everything to quieten them down. Backing shims, kevlar backing pads, copper grease. It's not fun when everyone within a 2 km radius of you knows everytime you hit the brakes in traffic.
Got a set of cheap, soft pads and put them in. So far so good. Hope they stay quiet, because they're actually pretty terrible at the whole stopping the car thing. But I'm hoping that's just because I'm used to the carbon ceramics, and I'll adjust. But still, takes about 5 minutes a corner to swap out when I need to go to the track, so win win I reckon.
