I just got these installed on my car last Friday. I went 235/40/18 and 295/30/19. Got them from Tirerack. There is currently a $50 mail-in rebate when you buy 4.

I'm still waiting for the breakin period to be over before I try pushing them too hard, but my impressions so far are positive. They are quiet (my GS-D3's got really loud) and my car feels more "planted". Handling and ride is much better overall. Not really sure if this is due to the fact that they're new tires or because of the tires themselves.

It hasn't rained here yet since I got them, so I can't comment on their performance in wet conditions.
