I just put a set of Yokohama Advan Sport V105s on my Cayman S Sport. Great highway tire and drove 1/2 day in the rain on the Interstate, no problems at 70mph. Not great for DE - a bit howly and not as confidence inspiring as the Conti Extreme Sports I replaced. But the Contis were cupping, which is a common trait for them. My LE came with Conti CS3s and they were a great tire, so I imagine the CS5s are too. And you can never go wrong with Michelin 4Ss. Forget the Michelin PS2s - they're expensive junk and I'm surprised they still sell them.

Just my $.02 for what it's worth. If you're going to be doing some high speed autobahn runs, you don't want to scrimp on tires. Good luck with your decision.
