Probably should have put this over in the "R" forum, but trying to figure out the correct thickness for the Brembo pads. Hawk lists the HB194 pad in the 0.570" thickness as correct (FMSI D592), but MM lists the 0.665" pad. Most other vendors say it is the thinner of the two, but some still say the thick one is correct (i.e., the Viper pad). Anyone?
