Don't think you need spacers no. That's just for fitting the brakes from a 225 Audi TT.
cheers for your reply
Only thought as i notice this on the brake upgrade page : Rear brake upgrade:
The standard 232mm Solids can be upgraded for the 256mm Vented setup, the bigger caliper just bolts straight on. If the calipers/carriers have come off a Quattro/4 Motion then you will need some 6mm spacers.
