StopTech Sport 309-Series brake pads - StopTech ST-40 caliper (D372/D609) [1 box required] 16.5mm thick

Great option for a street-driven car with ST-40 calipers. Nice bite, no fade in heavy traffic, and they last quite a while on the mean streets of LA. Towards the end of their service life, they do "clunk" at low speeds in the caliper (although, this may be unique to my calipers). Not a safety issue, but a bit annoying.

Good pads with smooth application and good bite, but after a few weeks with them I'll be replacing them. They must have some amount of metallic composition because everytime it rains and the car sits in it for a few hours, they stick to the rotors. Takes some reving and a clutch dump to break them loose, they you can feel the brakes pulse for a bit until the material wears off the rotors.
