The S8 and my previous RS2 is the only Audi's i've experienced warped discs on. S4/S6 has never had this problem no matter how the car is driven. So i have come to the conclution that Brembo Monoblocks really suck unless new or refurbished every 2-3 years
I wish there was a "Bolt on" brake kit from another Audi that would fit not using Brembo's.. Could be smaller brakes since the S8 really dont need 345mm to stop on road or track.
But for the moment i'm ordering the new seal/dust cap kit to do the refurbish my self.
Just my $0.02
