The caliper will bolt to the hub no problem, but you will struggle to find a disc. You're better off getting macan brakes or audi s5 carriers and 345x30mm discs. Another option is Macan 350x34mm but you will need to change the steering knuckles.
The Macan caliper is the same as the Q5, Touareg and Q7 use a 6 pot caliper. There are two versions of the Macan of the Macan brakes 345x30mm and Macan S 350x34mm, for the 345mm version no modification is needed. Just bolt the caliper to the hub and use S4/S5 disc. For 350mm version you will need new steering knuckles. The Touareg/Q7 caliper will bolt to the standard knuckle buy you wont find a disc, the offset is wrong so you will need a custom disc.
