I currently have a set of AS3 on my 09 370Z. Got a full set for about $1167 at Discount Tire here in Orlando.
My conclusions:
The wet traction seems to be pretty good. While I haven't had them long enough to run them through what I call "Monsoon Season" down here, they seem to shed the water quickly, and I've not had any hydro-planing issues, even while driving through puddles. Overall handling is good as well.
For regular dry handling, I would rate them as well as the Bridgestone Potenzas that the Sport models come with from the factory. Though they are not run-flats, and they do seem to have just a little bit more sidewall roll in heavy cornering, for obvious reasons.
All in all, I am pleased with my choice, though it is arguably still too early to say whether or not they will last the 30k or so miles that Michelin says they will.
