Porterfield - does have a web site, and also recommended by Elf (see his posting on April 8). Some interesting FAQ material. Porterfield also sells the Performance Friction carbon metallic pads that Ben mentioned.
I bought/installed a set of Porterfield R4-S on one of my cars recently (not the Sub). No problems in cold, and work fine warm. Don't have enough 'spirited' miles on them to really form an opinion yet.
