I'm running st45 front and st47 rear. First time trying Raybestos pads, but very happy so far. Only 2 track days but lots of street with them so far. Was thinking I might need to switch to something quieter for street driving after experience with race pads on other cars. Thought I'd do everything I could do to prevent having to switch pads. Tapered the leading edge of the pads with cut-off wheel/grinder and used disc brake quiet compound and ultra high temp grease everywhere I thought would help. Had a bit of squealing but definitely nothing terrible. Went back in and added shims and compound/grease in more areas. I get a peep every now and then but overall totally acceptable for me. We shall see as time goes on. Are your pads tapered?
