I have posted about these a couple times. I have a set to use as rain tires for autocross...so I actually haven't had them on my xfire yet.

However, I had them on my RX-8 and was very please with them. Not the *best* dry performer, but very good. They're hard to beat in the rain. Not great longevity, but fairly normal for summer high performance rubber. And you can hardly beat the price.
