Conversely, those of us buying a C7 should be able to discuss the C7 without people trolling the threads trying to derail them by bashing the C7.
What's funny is now that performance data has been obtained by third-party sources (i.e. magazines, online testers, etc.), it's not valid because they aren't "production cars". So, we will have to continue to endure the trolling, and the negativity and the sniping remarks until such point that those of us with C7's start posting drag strip and track data. Then I'm sure that data will be questioned because private owners race their cars at tracks and in conditions far better than magazines and GM do. The goal posts will continue to move.

The tires make up a piece of the difference, yes, but only 1s of 3s at VIR. But, let's keep discussing tires Anyway....I do enjoy the show.

I would love to see the C7 on Sh@tyear tires! Everyone keeps talking how the C7 is so much better, thank GM for going with Michelins!

And very well should be that way! Question is by how much and "if not much" why in the world would we trade or sell a GS for a C7. I have said all along...coming from a C4 or C5, makes perfect sense for the upgrade in power. If it would flat out smoke and embarrass my GS I would order now.....ugly *** and all. At this point, I want to see what the Hi-Po model does and looks like.
and hope GM doesn't price it out of my pocket

I will have to sit in one to make that call, I saw the TR at Barrett Jackson and it was nice but there again....not nice enough to step up from my GS plus I don't buy Vette's for the Interior.

sorry but anybody that has ever had to launch a C6 on stock runcraps knows how much garbage they are in a straight line. Not to mention they are heavy. Forget the badass michelins i've gone from crappy goodyears to nitto invo's and picked up almost half a second. Before I had my Z. The goodyears are literally rock solid sidewalls.
Doesn't matter much though since 99% of people will never see a strip. Hence why people saying changing different street tires has negligable effect on 1/4 mile. Most will only see the occasional random street roll race which means the only real factor their is the trap speed. And i'll tell you one thing 1 mph trap speed difference is not much to hang your hat on. That is easily close enough to call it a drivers race. To put that in perspective from a roll on 1 mph is about 10 feet distance between the from front bumper to front bumper in a race to 120. Thats not even enough to offset the extra weight of a passenger if the C6 driver is by themself. With equal traction that .1 in the 1/4 mile.
I'd just like too know where all the people went that 6 months ago was saying the C7 would be comparable to the Z06. Because if a C7 meets a Z06 on the highway and its a 117 mph trap speed car vs a 124 mph trap car that going to be a real bad beatdown. Definitly going to wait for the LT4 or 5

I doubt that going from a 325 Goodyear to a 285 Michelin RFT is going to have any positive impact on how the car launches. They are both RFT's, both with a short sidewall and the Michelin isn't exactly a DR compound (like an MT or Hoosier DR). The Michelin isn't good enough to offset 40mm of width with respect to hooking IMO.
Invos are not RFT's and thus they have a softer sidewall and lots of people like them.
Also, I think the difference in trap speed will turn out to be more like ~3-4 mph when owners start running their cars.
I say this as somebody apparently in your 1%. I probably made well over 100 passes in the last year alone.

Also since their was 215,125 C6 corvettes produced it is pretty fair 1 or 2% actually have enough passes to have a valid opinion in this matter.
The C7 will be a great road course car but it just doesn't do it in the straights. I think it's been seriously nudered to appease CAFE democrats and to add an easy mid model hp jump. It literally has a statistically negliable power to weight ratio improvement. 0.025 Hp to weight improvement and people question the trap speeds. If the C7 driver is 50 pounds heavier then the C6 driver it now has a worse power to weight ratio then the C6.
People will mention power under the curve and torque under 4000 rpm comparable to the LS7. Which makes a great street car and its good for a road course car if you do not know how to keep the revs up through the twisties. But means nothing from a roll. And only effects the hole shot at the strip.
