If you have the 20V turbo Brembo front brakes, you need to make sure they clear the calliper. I got a set of "Petal" 500 Abarth wheels. Width and offset seemed prefect, so I had them (expensively) restored, only to find they were far from clearing the callipers. The "spokes" in the original wheels arch or bulge outwards, to make room for the chunky callipers. Going to a larger diameter rim is no guarantee they will clear the brakes.
In the end I got a set of phone dial Alfa Romeo wheels, off of a Mito. They are _just_ touching the caliper, and that will easily be resolved with a 2-3 mm spacer.
