I did look in to this but the pedal feel is spot on and very responsive, just like OE in fact with bite right at the top of the pedal. From looking at the RS5 8pots kits etc available they all retain the OE S4 servo and work just fine too.Is there a limit to the size of discs and calipers the standard S4 servo can handle ?
As in more pots more fluid to push bigger area more effort
Would you benift more from the likes of hose upgrade and quality of pads discs etc ?
Just curious not done anything to my brakes yet but surely there's got to be a trade of between size of the components on the standard brake system ?

I used genuine RS5 lines with genuine S8 pads and genuine RS6 discs and everything works very well, the only thing I would add is more cooling to the brakes if it was possible as i do get brake judder from the floatig disc design when they get hot. I used them on the Nurburgring and they performed very well.
I've heard about people fitting the Porsche Mecan cooling ducts which I believe fit to the suspension wishbones but I don't know where the air is drawn from, either from under the car or the front? The S4 doesn't have any brake cooling ducts built in to the front bumper and behind the fog light grills there is other things thet would impede the air flow to the brakesGood to know, I'll prob end up with some sort of upgrade in the future,
I believe there's Porsche brake cooling mod for the front just diverts air towards the disc etc

Behind the passenger side fog light isn't too bad but behind the drivers side fog light are components of the Audi Drive Select system.I think @desertstorm has them fitted and I think an other couple of people as well
I'm sure you could cut a channel though the inner arch and adapt the fog grills for some flow
Thanks for the info ,it's going to be expensive.According to my research, if you get calipers off either an Rs4 or rs5 b8 then the supplied brackets will fit.
Audi don't sell these brackets without the calipers and I've been unable to find anyone who sells just the brackets.
The Brembo 6pot caliper fitted to the newer RS6/7 & S8 etc can be a better bet than the 8pot as it's a newer stronger caliper design and uses a large single pad
