[750hp]

I've seen MT S/R tires coping exceptionally well on a 600hp Cobra, so if you're saying you can "feel" the value of the Avons on public roads, you must be driving at 10/10ths.
I can understand the desire for some people to run billboards for the look, but as the Avons don't have that period style appearance, it then just comes down to the grip and performance they offer. I'm intrigued whether you could really feel any difference between them and MT S/Rs in perhaps anything other than dumping the clutch from a standing start.
