FIA Tire Size

I would go with what you have now in regards to sizing. Your car appears to sit "just right" to me. FIA cars do have a different stance/tire to fender clearance than a street 427.

Good point, thank you. So they have more of a rake...bit higher in the back?

I'm really outside the norm in that I went with 215/70-15 on the front and 255/60-15 on the back. Both are a just shy of 27 inches tall and fill the wheel wells fairly well. I had to shave the rear of the left front wheel lip down at the rocker slightly to get the front ones to clear.

I run the Power cushion up front, small yet tall. G7 in the rears.
Well balanced but not the best for track.
