I've been driving on Supersports (19/20") for about 3000 miles and am very satisfied with them.
On a dry surface, warm temperature, they are a bit less grippy than the Corsas, but they are better everywhere else.
Before my S IPS I had a LE, and the Michelins remind me of the PZeros, but a bit better.
Is a Porsche Cayman S quicker and faster? Yeah, probably, a little, if you judge things so parlously as to measure your life in tenths of a second. The Evora is a connoisseurís car, a driverís shibboleth and secret code, a prime number of a machine that is indivisible by anything other than itself.
