I was reading an ad that said the 18" Maranello wheel will fit a 456 (stock 17"). Is this accurate? Are they really the same offset, etc? I'm thinking about putting Maranello wheels and tires on my 456.
The offset on 550 wheels is 46mm front, 32mm rear if that helps you. I don't know what 456 wheels are, but they will be marked on the back if you pull them, you'll see it.
