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.

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.

I got Michelin Pilot Super Sports (non-runflat) on the car in March 2013 (285mm front & 345mm rear on stock size Spyder wheels), and absolute love them. I was skeptical that fronts would be too wide/tall, as the front 275mm PS2s barely allowed clearance of the tip of my pinky to fit. However, the MPSSs fit better than the PS2s and original GYF1s on the stock rims.
Bought car with 8000 miles with GYF1s on car. Tires were dangerous in the the rain, provided only 1/2 the needed traction in the dry (could spin the tires to redline in 1st gear if full power was applied [feathered or not] at any speed) and were dangerously twitchy and unstable going thru corners with surfaces that were not perfectly flat or giving it any power at all exiting corners. Very Unsat.
At 11,000 miles, I gave up and tossed GYF1s with almost 5/32nds tread left on them for Michelin PS2 runflats. PS2s were much improved over GYF1s for all conditions, but were on a quantum level higher for wet traction. I was surprised that the PS2s on the rear were way too narrow for the stock rim (over 1 inch LESS tread than the GYF1s, but still performed sooo much better). I also noted that the front PS2s were really too BIG on the front. I sustained a flat from a razor blade on a rear tire 8000 miles into their wear, but the dealer was able to patch. However, I was surprised that the runflats were later discovered (on the next tire change) to have evidence of interior tire damage after driving only 20 miles on flat at less than 40 mph. So not sure just how good the "runflat" mode is, if you plan on running the car hard after sustaining a flat, AFTER being repaired.
At 20,000 miles of wear, I replaced the PS2s with the MPSS (not runflat) as noted above. The PS2s lasted twice as long as the GYF1s performance per performance measure, but they then reached the inability to hold traction in 1st gear similar to the GYF1s, but not near as bad. The MPSSs were $1500 shipped to door versus increased PS2 price of $2200 shipped to door. So I decided to add a compressor and slime kit to rear hatch compartment and add me to my wife's AAA plus just in case. The MPSS tires perform better than the PS2s with the more complaint sidewall and wider contact patch and are still great in hard rain. While I have not tracked on a road-course, the tire seems more stable in every way. I hope to do a test & tune run at the drag strip just as a baseline, just for grins, but expect very reasonable times for a non-drag racer.
If you do not take long frequent trips in your C6Z, the MPSS (not runflat) is a fantastic tire of good value. Also note that I tried the MPSS on my wife's 2010 Maxima SV first and this tire made that car perform at a whole higher level, while still being a comfortable daily ride. This explains how the Ferrari 458 can perform like it does no relatively NARROW tires.
Also MPSS is rated at 300 treadwear (vs PS2s 220), due to dual compound tech (hard compound center & softer at edges), but time will tell what wear I really get out of it. If makes 20K, I will be more than happy at that price and performance level.
