I have a friend that owns a Z06 who began to mumble like you are now. He, too, wanted the ZR1's horsepower without the ZR1's cost. My friend took a slightly different approach. He already had an aftermarket induction and exhaust (including headers). A wheel Dyno pull saw him pulling 500hp WITHOUT a dyno tune. He then added a camshaft and the dyno tune. The car then netted 550hp. Factor up for parasitic loss, this is approximately 640hp which is what the ZR1 nets. It is still a Z06 but the car sounds wicked and pulls hard from about 2300 all the way up to the limiter. Another alternative for you to consider.
Just got the ps2's on my c6 less then 100 miles on them so far but have felt less rear end bump jumping when going around corners over 55mph. I spent a lot of money hope I did the right thing. I know I did not want the badyears that came with the car. When the super tires came off all the inside corners of the tires where worn to the belts. I was told that is because of how the toe in and out are tuned in the z06. We'll see if the new tires are any better in that department.
I would disagree (with all due respect) with who told you it was toe-in. Inward toe will scrub rubber off the outsides. Toe out willl scrub off the inside (and give you fits when driving straight). I believe that the problem is too much negative camber. Despite the fact that I autocross my streetdriven car, my suspension (front and rear) is set to straight up and square. For autocross use, the preferred toe is a slight bit out to aid in turn in with camber set a bit negative.
What's the opinion on the F1 Supercar G2? I have the G2 on the rear and the F1 Supercar on the front, both runflats. Impossible to give any comparison since I bought the car this way. Very easy to break loose with the G2 but again no comparison for me. My tires are stock 2008 Z size and about half depth. Moderate driving so far, need to get used to it first before pushing.
500 miles on the ps2's. great tire I did the right thing thanks to this site thank you all. I will have the alignment checked next week but the car doesn't get caught in road grooves like it used to. It was like fighting the wheel at times. With the ps2's it's much smother. I still have road noise but again not as much as with the supercar tire. Best of all the ps2's hook up much better.
From what I'm reading it looks like Michelin's will be the next tire. I have had PS2s on other high horsepower cars and do like them, great tires. What I am very impressed with are the Michelin Super Sport tire tests on tire rack. The times are very close to the PS2s. Are people finding that they're that good? I am very tempted to buy the Super Sports, why not. I get tires every year anyway, it's my daily driver.

Since my '02 Z06 is a multi-purpose car (autocross, track, and street), I employ the use of three different sets of tires. For this reason, I saved a little money on street tires and bought BF Goodrich T/A's (now a subsidiary of Michelin). They are good tires (UTQG 300) but do not compare to Michelins (IMHO). My wife's '04 coupe is only driven on the street and DOES wear Michelins. Even my truck has Michelins. Been using Michelins for about 37 years.
My impression so far of the Goodyear F1 Supercar G2 on the rear. Does not not hook up well cold, but improves above 60F. I was stunned never having runflats before when two Goodyear Tire Stores refused to repair a screw in the middle of the treadblock, right in the center of the tire. The tire was inflated as well, not run flat. I'm sure I will not buy runflats again now.

I've had the Michelins on the car for a month or so and I really like them. Compared to what I took off it's a world of difference. I can hear the radio now and it hooks up much better.
Goodyear F1s- overrated, over-priced and underperforming (quite frankly all of the Goodyear tires are compared to the competition)
Michelin PS2s- pricy but a very good tire with good grip for street use
Firestone - no opinion or experience
Nitto Invo - another viable and cheaper option. Decent grip, decent wear, but not a run-flat. Ok depending on application
Michelin PSC - Good tire for all purpose Z06 use...track, auto-x, limited street. Longer wear than a pure R-comp but more adaptable to rain, street use
Hoosier R6/A6- best you can get for track use or autoX. Can drive on the street in the summer, but will heat cycle and lose grip---and pick up every loose piece of gravel on the road. Only way to truly experience the power of a C6 Z06 around corners. Used up several sets on lesser cars and can't wait to purchase for my C6 Z06!
Wish there were more choices for my C6 Z06.
