Yokohama S-drive?

Does anyone have experience with the Yokohama S-drive tires? I'm thinking of putting them on a 87 911 w/17" C-2 turbo wheels. Thse would be mostly for street use and an occasional autocross. Once I get time again for AX/DE, I'll get a second set of tires and wheels.
They're resonably priced, and the online reviews indicate that they have low noise and ride well.
