My idea of a perfect C7 would have been for me to be able to order the 2LT base model (which I did) with the Z51 brakes and gearing, nothing more. Used to be able to do that sort of thing, unfortunately can’t anymore. Don

You appear to be responding to someone other than me. I didn't say those things nor imply them. Get over yourself (and your Z51)
I'd also get a little more familiar with your car before making misleading statements as well. There is no "Suspension" computer you speak of. All suspension components (non MRSC) are purely mechanical.

Regarding the "suspension computer" I mentioned,
Just which part of "I may be incorrect, but I also believe that....."
was not clear to you??? Do I have to come over there and draw you an f-ing picture????
You seem to have completely missed the plot with respect to my replies in response to the original "shocks and bars = Z51" nonsense.
It's hard enough following forum threads when some people cannot read and understand correctly.

83% of Corvette owners won't tell a difference between Z51 and MRC on the track, 12% will say they can even though they can't, and 5% will actually be able to tell the difference because they can run at the limits of the stock stuff.
Personally, I have always been a "buy the base model and modify it" guy. While the upgraded stock stuff, whether suspension or stereo, is better than the base model, the aftermarket has never let me down putting out stuff leagues above. So I don't spend my money on mediocre compromises like the Z51 package.....it still overheats, it burps oil into the intake, etc. Nothing is perfect and I've never seen a car you couldn't make better this side of 175K.

i also want to know
when you find out please post asap, bump it now and then, i dont get on everyday in summer, thank you, and did you notice that the chart you posted the rear spring rate is lower on the c6 z51 than the c6 base??

LOL...This started as a simple request for spring rates. No discussion of making Faux Z51's, Mysterious suspension computers, or all the bells and whistles YOUR Z51 has which makes it so superior. Chest pound somewhere else. Who's the retard here for blowing this all up? I'm tired of this (your) crap too BTW. There are a few threads on adding sways and shocks resulting in some very nice results. Go find them and lend your questionable expertise if you want to look like a big shot..

Only way to tell is for you to drive both. Opinions vary wildly on everything from "what's the best color" to "should I get comp seats" to "who likes chicken, who likes liver."

So if the Z51 is that bad what about the Base car?
My 2008 base car was lacking a lot when pushed!
I'm sure the base C7 is short of Z51 performance!
Z51 is the best package you could put on the car for the 2800 I spent!
The shocks and sways added are not a z51 replacement. Because you still have a too soft spring. The Z51 will drive circles around the base car.
Better brakes Tires and the whole suspension! Bigger wheels and the rest it's a steal. So thats why everyone wanted a Z51!
Base cars are sitting longer too!

(And some of us saved A LOT more than that $2800 due to the greater discounts available on the base car. With my mods, I'm $5200 to the good and have a car that performs, handles, and works quite well for the street and my occasional mountain runs.)

My point was, and I learned this with my C5Z, is that buying the upgraded factory model (which is all the Z51 is, a few easily swappable parts hold for MRC) is a waste for me. I paid for the Z06 motor and suspension and installed coilovers and a 408 stroker. At least I got the notch back.
Now that I have swapped wheels/tires, shocks and sway bars, what is left? Those are all parts that have better options in the aftermarket vs the Z51. My wheels are lighter and my tires are stickier.....
Coolers? Why? The Z51 drivetrain overheats on the track anyways, needs an upgrade.
Brakes? Crappy vs good aftermarket options.
The only reason to go to a Z51 is to get MRC and ELSD, the only two things you can't duplicate or improve upon (at least not easily). And if you are really racing the car, there are non-electronically controlled options that will easily outperform MRC and ELSD.

Several major problems with the "homemade" Z51 that you propose. Such a car will never be able to run the MSRC system that is an option only available for Z51s.
Could care less about MSRC! Not needed when the suspention
for the Z51 is huge winner. Trying driving one!
Also, you would not have the e-LSD feature that aids handling as much as traction.
Also, a non-z51 will miss out on the larger wheels, tires and larger/better brake rotors. Even if one could afford the fortune it would cost to buy the bigger wheels, tires and rotors over the parts counter, one would still end up with confused computers.
Just don't forget about the computer changes which all come along, under the radar, with the Z51 suspension changes. I suspect that by changing the springs/shocks alone, you could confuse the computer(s) that monitors the suspension and allows Stabilitrak to function.
I agree with some of your points on Z51 but your talking out of your hat here!
I hate to rain on anyone's parade, but facts is ("are" not "is")
facts.

facts.Not necessarily....Note the spring rate difference, or lack there-of, on the C6. Only the front is slightly different... I'd bet the differences are even smaller on the C7 because of a greater need to control front end roll since there are no rear bars on the base. There is also less unsprung weight (wheels, Tires, Rotors) to control on the base so less need for heavier springing.. Consequently the addition of Z51 bars and shocks feels about perfect on a base, and I'm pretty sensitive to this, having done spring and bar tuning on numerous platforms over the years.. I have no need or desire to change the spring rate as it is pretty spot on. As good as anything else I've driven, but I've only had 66 cars so I probably don't know what I'm talking about. Just curious on the rates is all...That was the original question afterall..
66 cars in your car lot or you buy and trade alot ? sounds like bunk!

you didn't save! Resale will cost the base car it is lesser to a lot of people that
is why the Z51 is much hotter seller than the base car. C7 buyers are more savy because more are returning buyers
Z51 is superior unless your just getting coffee then a z51 looks better!
Shop 1100 base cars and found few Z51's when I bought mine.
I didn't say the Z51 was bad. It's better than the Base when both are in stock form. I think you missed my point.

I paid for the Z06 motor and suspension and installed coilovers and a 408 stroker. At least I got the notch back. That cost you more than the difference
and resale was toast. Real C5 Z)6's still demand good money.
C5's No!

The whole Z51 package for 2800.00 when it was in VERY high demand higher than EVER before. Anf frankly was brainless to not get.
You get a ton of difference for the 2800.00

You really don't have a clue. I seem to remember you were the same way back in our C6 days Circa 2008...Glad you're happy. So am I...
You can get off the Z51 bandwagon now...although it does seem to be a Dck extender here on the C7 forums..

When I bought a base car instead of a Z51. But the difference was not
near as much.
So I bought the z51 sways, shocks, drilled rotors, Z51 springs and installed all myself and a blower kit installed it myself too and had a lot fun.
But now it's different. With all the differences you can't change.
The list is long!
Seems your totally clueless thinking your sways and shocks equal a z51. Your missing better wheels and tires. Better cooling z51 actually has working vents than run air through real coolers.
The base car was a bad choice when the Z51 was only 2800 extra!
EXACTLY why Kerbeck at times had 150 of base cars and 7 Z51's and 4 0f the 7 were vert's!
Seems you need Corvette lessens. How many of the SAID 66 were Corvette's? I could come up with a number if I count some junkers
from 30-40 years ago. Doubt you have had more Corvette's!

I thought you were still on my ignore list from 6 years ago. These posts and others of yours on different threads have reminded me again. Don't worry...I've fixed that (again)..
See ya.
