Good to know Marty....thanks! Ferrari never will talk about this or publish this info. I have personally seen other brands with different than factory front to rear overall ratio difference really mess up at track events. 1 student of mine in particular in a 991 Porsche at Sebring. Porsche claims front to rear % difference in overall size needs to stay below 4% and I've found that true with 997/991 Type 911 cars as an example. However if I do aftermarket wheels again I will stick with 20" as I like lighter and I do not like super skinny tire profile. I do like the "looks" of what you did with your F8 but I consider other things before looks myself....it's personal preference. I do like how Porsche has gone to 20/21 set up on the GT cars but maintain a beefier tire sidewall and less wheel gap.
I have seen these wheels on eBay from a place in Florida. Just search Ferrari F8 Wheels and you'll find them.
My friend also got the same size wheels made, but he is running a wider tire Image Unavailable, Please Login Image Unavailable, Please Login
