As posted at the time on I was reluctant to have the 47i6 upgrade on my car as the only issue I'd had with the original brakes was low-speed brake squeal and to my own satisfaction I'd sorted that; and I'd driven a number of 47i6 modified cars and agreed with owners of that: 1) the pedal was softer and/or longer, 2) the initial bite a lot less, and 3) the brake dust more: but I was persuaded by Audi UK and had a free 2nd service to boot.
So I gave the 47i6 setup 1000-miles to settle and then the low speed brake-squeal began and I applied the same resolution and fitted shims and that was sorted, again.
As most will know I've tried a number of alternative pads since but have gone back to the 47i6 arrangement with shims and NO absorbers.
ANYWAY to the point of this post: had a 2012 RS3 in by garage on Saturday last to fit some cat-by-pass pipes and some TLC to the 'ORIGINAL i.e., NOT 47i6' front brake hubs/spiders and, having completed everything was invited by the owner to evaluate: 500-yards and I'm saying these brakes are superb; the pedal was way up on mine, the bite immediate, and from what I could tell the brake dust 20% of the 47i6 arrangement - and all this brought back memories of my own original arrangement.
I have to say that if any 8P RS3 owners out there with original brakes craving for the 47i6 upgrade B E W A R E; the original brakes are, in my view, everyway better! And that may just be the pad as other than software change to introduce a 'brake-wipe' when the windscreen wipers are activated I can't see any other change but there's a whole lot of difference in the feel.
Original brake pads with a 'flat' back-plate were:
Brembo: 07.8560.78
Audi: 8J0 615 115R (20S)
47i6 brake pads with a sculpted back-plate and maybe softer material are:
Brembo: 07.8560.82 and 07.8560.83 (2-numbers as they're directional)
Audi: 8J0 615 115S (20S) and 8J0 615 116K (20S)
If anyone has a set of the original 8J0 615 115R (20S) items then I'd like 'em so PM me with a price as I'd like to do a back-to-back.
