I contacted Robinsky to ask how he was getting on with his set - his feedback is very positive for these discs as an alternative to the orignal Audi fitment. I am probably going to try them combined with some EBC Redstuff as I dont think that the Audi OEM pads are that good either.
I've been championing the Alcon set up for ages now....
Looks better than slotted AP discs, any day in my opinion and I bet you don't get the chatter feedback either.
