I would recommend talking to Andie at carbotech (go to www.carbotecheng.com to get the #). They sell many high quality pads, are all serious enthusiasts, and know their stuff when it comes to brakes. I talked to Andie when I got my pads for the factory calipers and they actually made a set for me! He also persuaded me against upgrading the rears. Besides being extremely helpful, I've heard lots of good reviews about their honesty - I know a guy they told to go somewhere else to buy his Hawk HP's b/c they were cheaper. I'd wager they could get you exactly what you needed or send you someplace that could.
Sorry it sounds like a shameless plug, but when a little shop specializes and gives good service I get excited <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
