We joined a spirited club drive a couple weeks ago. When we got home I happened to look at the car from the bottom of the driveway and saw cords on the inner edge of the RR tire. I knew I was going to need tires soon, but I didn't realize that they were that bad. We were heading out of town so I put off buying new tires until yesterday. I ordered a set of the stock Pilot Sport 4S ZP from America's Tire. They showed up this morning and they were able to squeeze me in to have them mounted after lunch. Then I had a new experience. As I pulled out of the parking spot I could feel the front tires sliding across the pavement. With the track alignment there's 3 degrees of camber in the front so that wasn't totally unexpected. When I pulled out of the parking lot I gave the car a reasonable amount of throttle but the rear end slid out like I hit a patch of ice. I decided to take an easy drive to wear the mold release off the tires before I pushed my luck anymore.
Since I'm probably not going to be doing track days anymore I'm going to have the alignment put back to stock or an at least closer to stock. I don't see any reason to run -3/-2.5 degrees of camber on a street car. I'll probably shoot for -1.5/-1.0. The C8s seem to like a little more camber in the front to reduce the factory understeer. The reduced camber in the rear should help it launch harder too. ;^)
