What's the widest wheels possible? Perhaps it's best to stay with the stock sizes as I'm sure Ferrari didn't put all that R&D into it for nothing but for a street car, I would like as wide as possible at this point.

20x12 I was told by a shop, can I go any wider?

19x9.5 at the front. Sound right?

Will probably go with HRE's or have been contemplating some magnesium Neez wheels

 

12.5 i've seen. 19'' though.
