Would there be a measureable difference at the track if the same pro driver tried both? My guess is yes but it would be slight. I like it because it's unique and because I like the idea of the placebo effect and have convinced myself that I'm faster because of it
If you are looking to get around a track fast 18s vs 19s will gain you more than a CF roof.
