Disks and pads for it from Goldwagen is front and back with pads i think just shy of 10K.Thanks I did an interesting exercise pricing the OEM brake job. The price difference is eye watering. I decided to go with a sort of mid-range option (Hella/Pagid) and do front + rear just so I know I won't need to worry about brakes again for a while.
The worst comment I've seen about them talks about them wearing a little bit faster than OEM. For the price delta (basically all parts supplied and fitted for the same price as one front OEM rotor and wear sensor), I can live with it. I wouldn't hesitate to spend money on the 4C or M5 but for the Cayenne it makes no sense to be spending a significant % of the value of the vehicle on this.
On another note, I have too many bills at present
My little big fuel leak is a 15k fix to replace the commonrails that cracked and the high pressure lines.
