From the article about the gt3 Imagine if the z06 had a clutch that rattled, a clutch that required an alarming amount of force and a long throw shifter. They would harp on it, but since it is the gt3 then it is Porsche paying homage. I may be looking into this too much but this article seems to have A LOT of bias.

I'm a huge corvette fan so I can't be totally unbiased either though

 

i love that of all cars the Boss came in so far towards the back.

 

The R8 GT in the only picture that I can tell what tire its on is wearing a P-zero Corsa. (R-comp.)


So that makes at least four on "cheater tires".


Damn chevy for cheating!!!

 

wow very nice race!

 

my car sits on r comps and i drive it every day. i even rented it out to a guy and his wife for 3 days and they put 250 miles on it. I don't know where you live, but it's realistic here...

 

To be honest if RA1s or R888s fit my car it would be wearing those for track tires. they have a softer sidewall then the cup tires, but they have more grip. It sounded like from what they described the cup tires on the Z06 were even bigger 'cheater' then normal cup tires. I don't know about that. I have never seen a custom cup tire, but maybe they exist.

ACR Tires

All the cup tires look pretty much the same to me....

 

ok sorry in cali they are but most people in most areas do not consider r comps as street tires.

all I'm saying is that you can't compare cars of similar speed with totally different tires on them. aka the boss 302 LS against the evora s, cayman r & 1M. Put r comps on them all and than run.

good point, but then again why would they even compare those cars in that broad of a price range right?
This test was "because they can", now if the cars were all had similar performance then yea I'd argue the tire compound.

 

It's all about how much of a tire budget you have. You could prob. run R comps full time on a Miata for less than 911/Vette high-perf street tires would cost. I'm currently running R888's on my S2000, and they function perfectly fine on the street, just w/ a relatively short lifespan.

 

And they all have the same treadware. The ones on the vette are runflats, so you get a stiffer sidewall, but also about an extra bit of weight.

There are several cars that have an r-comp tire as either an option, or the only tire it comes on. It may not be practical to drive on every day, but then again, most of the cars that they come on would only be driven in the dry anyway.

From their last review of the 2012 gtr and Zo6 carbon you see that the zo6 carbon is already nearly as fast as the gtr when the Z06 was on the PS2 tires. (I think that it was on PS2's, I couldn't tell, and they never said, but I believe that it was before they started offering the z06 on cups.) http://www.youtube.com/watch?v=wfzqmpQQfOs So putting the Z06 on Cup tires in this test would have made it faster. I am not saying that it is fair that some of the cars were on normal tires, but they test the cars in whatever spec the manufacturer gives it to them in. In reality anyone who owns one of these cars that is serious about tracking them is going to put them on r-comps anyway. Heck you'd be silly to track the Z06 on anything but Hoosiers. They are the stickiest and cheapest tire you can get for the Z06.
