B9 S4 S5 calipers

Anyone know anything about fitting these to mk5/6

I know they bolt up to the spindles, not sure what rotor would work with them.
I have a pair coming just not sure what rotors to get.

If the spacing between the hub face and the side of the spindle that the caliper bolts to is the same between the B9 and the GTI shouldn't you be able to use the same rotors that the B9 S4/5 uses?

Well yes but I don’t know if the spacing is the same. And the rotors are not cheap to buy just to experiment.
I will ask the junk yard of they can send me rotors maybe too with calipers

Yeah if they can get them to you cheap I’d definitely pick those up just to test fitment.

Also, you could do some part number searching and checking to see what cross compatibility there is between different models. For example, we know that Audi S3 spindles are the same as a few other models (CC, Passat) and this part bolts up to our cars. If that part number matches those and the wheel bearing/hub assembly matches then the S4/5 stock rotors *should* work.
