Default Z06 vs. 2017 GS

In hindsight, is there anyone that would have gotten a Grand Sport, if it had been available, rather than your Z06? In the process of ordering a 2017 and wanted some input from those who have 650 HP, instead of a measly 460...

Unless you spend as much money as you would on a Z06 to get a proper mod with the same durability it is just a cob job. At the end of the day it is still just a GS with a modded engine that may or may not be what the owner thinks it is. Nothing better than a fully engineered product that comes with a factory warranty. Throw a 2.3 supercharger on an LT1 and blow the engine, transmission or diff and see what GM tells you to do with a warranty claim. Resale value will be in the toilet compared to a stock GS since most buyers are looking for stock.

Z06-lite? Certainly not when you can have the full body and great tasting Z06.

Nope!
The Grand sport is a beautiful car. But I wanted "the real deal"! The Z06 badge means one thing. Bad to the bone.

Since the GS is based on the Z06, except for the engine and transmission(if a M7) or rear end(if an A8), wouldn't a GS with an aftermarket 2.3L supercharger and with the more aggressive gearing that the GS has, which is same as the Z51, be even "badder to the bone" than the Z06?

One could likely take a C6Z06 and add a bunch of stuff making it bad to the bone too. However, that would be beside the point. Apples and oranges when comparing stock to modified.

Good comments, all. I struggle with the concept of how often I would use the extra 190 HP(!). But that's not the point, is it??

Hit and miss then you pay the costs on the gamble with out GM's approval it's on you. I did that with my 2014. Bad experience
other's carry that too.
Your aggressive gearing is more regressive.

If you are struggling making a decision between the two AND if you decide to buy the GS instead of a Z06 I predict many times you will be thinking maybe I should have bought a Z06 instead. If you buy a Z06 instead I doubt if you will be wondering whether you should have gotten the GS.

I have a turbo diesel pickup, a 3.6L Cadillac ATS, and a 2016 Z06 and very rarely do I use the full power of any of them but it is a nice feeling to have that power when you want it.

Happy decision making

If the Z were NA there would be no comparison. Since the extra power is coming from boost, and you are only in boost a small percentage of the time outside of a straight line, the GS is pretty close actually.

???
Pretty much all of the tq of the Z06 is down low at 1500 rpm. Please explain your logic. If anything. A higher revving NA is more peaky and have to wind out a bit more in the upper RPM to extract the performance.

I thought "pretty close" only counted in horse shoes and hand grenades? The cover uses the word "best"...and I just don't think it is, regardless of whether it has forced air or not.
