Was looking at fitting a set of jag wheels that look like audi a8 lm's (dustbin lid ones).

Does any one know where to get hub adapters or is there other ways to adapt the hub to seat the wheels.

A4 PCD - 5 x 112---35---57.0

Jag - 5 x 120.65---18 to 20---74.1

Or is it not worth bothering. Any help would be very much appreciated.
