Hey, no fair getting attacks!! I was gonna get some for racing on, if I can ever save up the money for 'em...
Actually, the bronze attacks would look really good on a MBP car!! I don't think there's very many black WRXs on bronze rims, and like Matt says, it looks really sweet.
You already mentioned the Kuhmo 712s. I've had a set on my SubZeros for about 15k miles now, and the wear's not too bad. Esp. considering I've got an autocross on them! For the price, I think they're a really good tire.... best bang for the buck IMO. Austin's (LabMonkey) got a set on his Mustang too.
Check Tirerack for tire reviews... there's usually a ton of decent reviews by people that drive like us (too fast). Plus the tire rating guide there seems pretty accurate.
