I agree, and think a staggered wheel & tire set-up is ideal for handling balance as well as aesthetics.

I hope that snap oversteer (my biggest concern with the 818) has largely been mitigated by FFR with a solid and balanced chassis and suspension set-up. The quote from the Road and Track article:

"the 818's a true sweetheart, pushing the front predictably before uncorking its tail in a lazy slide"

seems to imply that they got it right, and that it won't be a tail-happy nightmare.
