Good evening. I have a Seat Leon 1.8 TSI MY2010 facelift and I was searching the web about info on fitting the rear S3 8p brakes to my car (exactly the same as the r32 rear brakes). I came across with this topic and as it was by far the most misleading, I decided to reply. Teutonic_Tamer you seem to be a very ignorant person so please don't right things that you don't know. You wrote the following.
The R32 rear brakes will NOT fit the Edition 30, nor any other front wheel drive Golf V platform car.
The R32, and the identical spec S3 rear brakes will ONLY fit a four wheel drive car. The hubs are different, and the wheel bearings are different.
If you really wanted to put the R32/S3 rear brakes on a GTI/Ed30/Leon Cupra R/Octy vRS - then you will need some serious modification to the rear suspension setup, including:
- two new rear hubs
- two new rear wheel bearings
- two outer CV joint "housing" (to support the rear wheel bearing)
- two new handbrake cables
- along with the entire rear brake setup (calipers, caliper carriers, discs, backplates, pads)
Boy, there seems to be some mis-information creeping into this forum! 
The only mis-information regarding this topic is you!!!
The rear s3/r32 brakes are a direct fit, I mean plug & play completely to any MKV platform based car. You just take the stock off and place the new ones. No modifications, no hubs change, no hand-brake conversions, no rear wheel bearings. PLUG & PLAY!!! How did you make all this up?
Here are some photos of the rear s3 brakes fitted to my car.
