Hi All I need to change the rear pads on my 2016 A3 8v 150tdi quattro. The disks are in reasonable shape but I considered replacing them too while everything was in bits. Fronts are 288mm and rears are 272mm. I noticed there are drilled Brembo disks available that would fit. I am considering changing them all to these from the solid disks currently fitted. Are the drilled disks noisier in use than standard solid disks? Is braking any better with drilled disks? It seems to be the same pads for 288mm or 312mm front disks. Is this correct and is there an advantage (heat dissipation etc) in putting the larger disks on? Is it easy enough to put larger disks on or do the caliper carriers etc need changed?
