Does the R32 have the alloy hubs, like an S3?
I remember DaveB saying that if the BBK carrier mounts from the wheel side of the hub, then because it is different to the GTI version (a few MM thicker, thus pushing the caliper further outboard) it might not work.
EDIT - If you get the Brembo kit, DON'T spec drilled discs, they're rubbish and crack for fun. They're also horrific on spares like caliper seal kits etc, so think about maintenance costs too, they're not fit and forget like OEM brakes they take a lot of care.
The VWR kit is a much better proposition, along with the likes of Alcons and APs.
