For autocross, I am a very big fan of the Dunlop Direzza Z1 / ZII Star Specs (200 treadwear). That's what most of the guys I run with use, on all varieties of cars. I am still on a set of the previous generation Direzza Z1's. They are a very sticky, but most importantly are very predictable when they're letting loose. They are also a great tire for the street.
If you want SUPER sticky, a set of Michelin Pilot Sport Cups will fit the bill, but they price out nearly 2.5x the cost of the Direzzas, and may bump you into an improved class as their tread rating is only 80 - here in the US, running with PCA you can go as low as 180 treadwear in stock classes.
The Bridgestone Potenza RE-11
A are also highly recommended for autocross, but I haven't had experience with them - only one or two guys running them at our local track so far.

Completely agree. I don't think there is anything out there as sticky as these tires, other than Hoosiers slicks . HOWEVER, at about 60 MPH ( and this is not when they start wearing out, I'm talking about them while still new..) they start howling pretty badly. At 70 - 80 + mph they are so loud, they will drown your stereo and you'll feel as if you need earplugs to tolerate driving your car. I turned them back in one week after I bought them. But a heck of a fun week when I was not on the highway, whipping the car into sharp turns at stupid speeds without the slightest slip or slide. Jaw dropping grip.

Are your freeways all concrete up there? They were definitely loud when I lived in Socal on the concrete freeways, but on asphalt I have no issues with the noise. Then again, all tires seemed to be loud on the concrete...

So it begs the question : Asphalt or Concrete highways in Pa ?

We don't do concrete highways in the Northeast...they're more dangerous in poor weather conditions, and the way they treat the roads out here with snowplows...they would be replacing the roads every 5 years anyway like they do with the asphalt - except asphalt is a lot easier and cheaper to patch or replace. Concrete being smoother, it does give you a little better gas mileage - but your tires don't stick as well to it as they would asphalt.
There's one spot at the airfield where we do autocross that has a big patch of painted concrete (the rest is asphalt) and it's always fun to watch the 911s hit cones sliding out there, especially in the rain.
