I'm on my second set of this pair. I used them for street, long distance highway (to the Left Coast and Rally 12, then back to the Right Coast this summer), and on the track at UMC at Rally 12. Great all-around tire for these cars. I've driven them back-to-back with the Goodyears. They aren't particularly noisy--about the same as or less than the Goodyears. I run 32 Psi and don't have any problem with them wearing out in the middle, however, the front and rear tires will wear out on the inner edges with the stock camber settings.
I moved the front and rear camber settings to almost zero camber to improve tire wear and life (actually about -1/4 degree), and on the street that works great. On the track, the tire will slide just a bit more easily, but it also slides more predictably, IMO. Unless you are actually RACING, you I doubt you'll notice the difference, and you'll get 5000 more miles out of your tires before they are down to the wear bars. Fair trade-off for me.
