z51 vs. stock
You know how these discussions take on a life of their own.
For me resale on my upgrades is not an issue. I will likely keep this car for several years. As much as I wash and wax the damn thing, you'd think it was one of my children.
Track for me. I don't like racing in a strit line or even an oval for that matter.
You really don't have to spend a ton of money to reach the performance level of the Z51. Is it more than the $1700 for model difference? Yes, a little. But, you have more options.
I can afford what I want, but like I said before I would buy a Z51 if it were the right color and price.

Its all good and each to their own. Thats why they call them options and thats why they come in different colors. Not everyone is going to want, or "need" the same thing.Good luck with the modifications, and no you don't have to spend a ton of money to surpass C6 Z51 performance in a base car. You don't really have to spend a ton of money to get a base C6 to C6 Z06 performance levels for that matter. Certainly not funds equaling the difference in price between the two cars.
However if things like warranty, and dependability are paramount for the owner, then he or she "may" decide to make a different decision.
Having modified my last two Vettes, I prefer to keep this one basically stock. Thats why I chose the Vette with the most factory performance potential available that I could still remove the roof/let the top down on. But thats my preference. Someone else may decide something else.

See how you asked a straight forward question and they come out of the woodwork attempting to badmouth the Z51 equipped C6?
If you bought a Z51 C6 get used to it. The "Z51 envy" that some of these base model and F55 equipped C6 owners have I mean. It happens when you realize that you just bought the Vette on the bottom of the Corvette performance rung.
It would be even worse if you had bought a Z06.

Many times if the car has more power under the hood, more aggressive gearing can be counterproductive due to traction issues.
The Z06 already makes 505hp and is traction limited on it's street tires as it is. If it had the gearing of the Z51, which is approaching 3.90:1, traction would be even more of an issue on it's street tires.

W/ a good set of drag radials the z51 gearing should help elapsed time in a drag race one would think. that is if the clutch will hold up.

The C5 Z06 and the C6 Manual Z51 do indeed have the same gearing in gears 1 through 4.
The C6 Z06 and the C6 Z51 do not.
Except for the C6 Z06s, the C6 Z51s have so far proven to be the quickest stock C6s out there, with 9 of the top 10, bone stock quickest non Z06 C6s being Z51s.

Well thats cool then. Thats probably what he meant. I was so busy drooling over the test ride, I wasn`t even sure what my name was after...
Too bad they didn`t want to sell below MSRP and I had to buy mine from Rick Daniel, which by the way was a wonderful experience.I took my F55 and ran a 12.39 bone stock, but it was amongst a few mid-hi 12.5's. Since I began to mod that very week, I was unable to back it up, and I said nothing. I'm fairly certain with some practice, and luck, I could have matched the quickest time here, but with only 5 passes on a car with 400 miles, it was tough to do. It depends on the driver. These tires suck too. With headers I'm still not able to run 11's. It's not the gearing, for me anyway. I think the car is getting quicker as I break it in a little. Running through the traps in 3rd is an advantage. Also, there is no doubt TM plays a role, this car is a dog compared to my C5 Z06. It's .4 slower, and the gears don't give you .4
I'm not sure why we're arguing a point we can't prove anyway. I offered to swap cars at the track with a Z51 owner to see what would happen no one showed up.
I acknowledged earlier that stock to stock, the Z51 IS slightly quicker and I do mean SLIGHTLY. change the base's tires and it's a different ballgame.
The drag results are also skewed because people that intend to drag will likely purchase Z51s. The number of Z51s sold outnumbers the base as well.
