For k11 brakes, you need:
Hubs
Calipers
Discs
Wishbones
Drivrshaft (dependant on year of your k10)
If you've lowered your k10 stupidly low like me, then you may need to shorten the shafts by 10mm otherwise they will bind and give you a terrifying judder when cornering. (Not fun)
The k11 wishbones are 10mm shorter than the k10's
