EBC Blue stuff on the front and yellow on the rear atm. Can't fault them yet. Yes they don't bite down hard like HC+ but I don't find them any worse. Both are similar
when cold and I haven't had them scream like Roy either, ala the f3000's.
Quite right they are AP style pad, so use whatever compound you like (they don't cost any/much more than the sumi sized pad)
Also, why do the rear calipers? ksport/g4/d2 front only is proven, works, provides fantastic stopping power.
Though I'm watching Ash's comments on the el-chepo dba5000 style rotors. $900+ for dba5000's that are made from some compound of bega cheese
In saying that they did do a good job and I had no problem with them, but didn't get 12 months out of em.
