Managed to get my hands on some S7 calipers today, and i've been looking about for rotors for them and pads. I've been recommended EBC Redstuff pads, but online they have mixed reviews - are these worth the extra money? Also, I've not been able to find anywhere that does the 400mm discs, as euros and all others seem to only do 356 max? Does anyone have the audi part number for the 400s? or did they change to 356 early in production? Cheers!
