They still make em. It looks like if you're used to the usual $350 per tire price point we've historically paid for the Pilot Sports, you'll want to go with the new Pilot Sport Cups. The Cups are an R compound so they're a hell of a lot stickier but from what I've heard they wear like iron (compared to other R compound tires I'd imagine).
Thats probably what I'll go with, but I know the Sport Cups haven't showed up in any quantity yet. Other choices would be Toyo RA1s, Kumhos, and of course, Hoosiers. I've heard good things about the Toyos too, but I'm not sure they're available yet in the sizes we need.
