Sometime back I upgraded my son's Passat to have the large A8 rotors. You can do this if you have spare TT caliper carriers and I did.

Only problem is that the spare tire will not fit over these.

Would appreciate a little help on this. The wheel can even be a steelie but needs to come from an A8, or equivalent Audi with similar sized rotor and caliper as an A8.

The passat has 5x112 wheels.
