Another interesting change the weight distribution is now 49/51 how GM put more weight at the rear? i don't know..

At 105K the 2012 Z07 has become heavier, and appears to be more refined and easier to drive. It is also slower in my opinion. Put the Z07 suspension package and tires on a 06' Z06 at 3150 lbs and see what the numbers look like.

They will look like ZR1 numbers and that is exactly what GM does not want you to see. Now the performance between the 2 have become blurred and that's just not good for business. Don't believe the hype.

You say blasphemy?!?! This guy is crazy??? GM spent millions designing this thing!!!!

The Z06 with Z07 package with professional test drivers in 2011 lapped VIR (Virginia International Raceway) at 2:53.5. To give you an idea the LP640-4 SV did it in 2:53.9 and 430 Scuderia in 2:54.6

As of now the SCCA T1 LAP RECORD (SCCA showroom stock Touring One class) Amatuer race class which is made of up 90% Corvette's (no Z06's or ZR1's allowed, just base C6Z51 and C5Z06's) is...hold on to your pants 2:01.24. That is a base Z51 with a T1 suspension kit and a set of Hoosier A6's (standard Iron brakes with Hawk DT-70 pads) and an amatuer race driver.

I love what GM has done with the car, but after you get to a certian point, it all becomes just for browny points and the REALLY fast track guys know what to use.

But 2:5x vs 2:01 ? No way.

Also, you should give the PSC's a try. They're pretty amazing. They are more expensive, but tirerack shows:

345/30ZR19 PSC @ $583
345/30ZR19 A6 / R6 @ $423

You can actually drive to an HPDE on the PSC. Street driving with Hoosier's is likely to leave you stranded with a flat. The new Z07 PSC's are actually runflats!

Also, the Z07 brakes probably aren't up to race duty, but you can drive to the track on them, and they'll work pretty well at the track and get you home without machining the rotors in half when they are cold.

These things are about compromises.

A real race car is trading off all the street niceties for track performance. Max bang for the $$, and who cares how it behaves on the street.

Some of the things coming out on the factory cars now are trading $$$ for very good performance at the track and still retaining good street manners.

You'll NEVER be able to take advantage of these tires on the street. If you are at the point where you are maxing these tires on the street, one of 2 things will happen:

1) You will go directly to jail and lose your liscense indefinately
2) You could kill yourself or worse someone else.

Doesn't everyone understand, these tires are a marketing gimmick to give the last C6Z lap times so it ups it's reputation in the magazine numbers game. Real life, they are a waste of time on the street and track. They wear too fast and you will never be able to take advantage of the grip they provide on the street (no matter what you think). On the track, they are nothing but overpriced R compounds, and Hoosiers will smoke them lap time wise for 1/2 the price.

The unfortunate part is this version Z06 was built specifically for the track, but EVERYONE who ACTUALLY does track days knows you just buy a standard Z06 and put some Hoosiers on it for 1/3rd the price. You don't waste time with carbon brakes and OEM pilot cups unless you have money to burn. A stock Z06 with a set of Hoosiers will be as fast or faster. So you buy a regular Z06, get an extra set of rims and switch between track/street.

I could see how the "general public" could see this as an awesome package, but if you do what this package is intended for (track days), you will find, you are better served with a stock Z06 and a set of Hoosiers.

How was the track prepped? What was the ambient temperature? What was the altitude? Did they posted corrected or uncorrected times?

It's not about believing the hype. GM can't help that people on forums don't understand that you cannot compare 1/4 mile times from totally different sources.
