Well, Chevy seems to say that for the C7, Z51 IS a model:
AVAILABLE MODELS
Stingray Coupe (1YY07)
Stingray Coupe with Z51 Performance Package (1YX07)
Stingray Convertible (1YY67)
Stingray Convertible with Z51 Performance Package (1YX67)
Z06 Coupe (1YZ07)
Z06 Convertible (1YZ67)
Note that they have their own model numbers. This was not the case in the past.

Do me a favor please?
* Go to www.chevrolet.com
* Select Performance (upper left)
* Select Corvette
* Select a MODEL, I see only TWO choices; Corvette Stingray and 2015 Corvette Z06
* I repeat, I see only TWO models, I do not see Z51 available as a MODEL
* Under Corvette Stingray, select Build and Price
* You're now on Step 1 Body Style, select NEXT STEP
* You're now on Step 2 TRIM Level
* Notice Z51 is described as a Perfomance Package, not a seperate MODEL
What am I missing?

Excuse me, if one were to delve a little deeper one would realize they all may not be c7 fanatics?

Unlike in the past, when a dealer orders a C7 Corvette there is NOT the option to check the box for RPO Z51. Instead, we must order Corvette model 1YX07 (coupe) or 1YX67 (convertible). As Zymurgy correctly pointed out above, the model codes for Stingrays without Z51 are 1YY07 (coupe) and 1YY67 (convertible). At no time is RPO Z51 ordered as an option. In other words, for ordering purposes a coupe or convertible with Z51 is a separate model; you can decide whether not it's a separate model in other contexts.

From what you're saying, the team that configured the ordering process made the Z51 a seperate model. Okay, I understand that. It appears that there is a disconnect between the team responsible for the ordering process and the marketing team that configures the chevrolet.com website. Refer to my previous post #21. On the chevrolet.com website, there are only two models available; Corvette Stingray and Corvette Z06. To find mention of the Z51, you need to go to the Trim Level page where Z51 is described as a Performance Package. Until Chevrolet changes either the ordering process, or the chevrolet.com website, I do not believe we wil have a definitive answer. But until that aphappens, I will say I understand your point of view.
Thank you

If anything it makes the car slower, cause it adds weight, but no horsepower!

When GM originally set up it's RPO coding, it was broken down onto classes and then each class started with an A, B, C, etc. GM reused the coding as needed over the years across the entire GM product line, not just on Chevrolets or models such as the Corvette.
We all know the the original Z06 RPO was used in 1963 but in 1978 it was "luxury Interior equipment". The in 2001 Z06 was not a RPO but a Model and in 2004 the Z16 was a "Commemorative Edition PKG" on the Z06. In 1965 Z16 was used to identify the special Chevelle Malibu SS with the 396 engine(only 200 built). In 1978 the Z16 was "Sport Décor/Black Knight". In 2010 is was the RPO for the Grand Sport.
In 1978 the Z52 was "seat-full foam". Z51 nomenclature was not used in 1978.
In 1984 the Z51 was a "Performance Handling PKG". No Z52 in 1984 through 1986. In 1987 there was the Z51(1,596 built) and the Z52(Sport Handling PKG) and 12,662 were built. Apparently people didn't want the rough riding Z51 , but did want a little softer riding Z52.
For the C6 Grand Sport coupe with a manual transmission, each and every one had the following three RPO's.
Z16 "Performance Package Grand Sport"
Z51 "Performance Package Handling"
Z52 "Merchandised PKG dry Sump System".
As you can see, a RPO code today has really nothing to do with RPO codes of yesteryear.

[QUOTE=petepd;1589180822]YOU are correct. Z51 dates back to at least 1984 (I had one, TERRIBLE ride) and I think it may go back to 1963, but I can't find my black book to confirm. It is most assuredly an option, in some ways similar to the Pontiac GTO, which was an option on the Tempest, at least at first.
If anything it makes the car slower, cause it adds weight, but no horsepower

I too had an '89 with Z51 option. Worst riding and handling Vette I ever owned. My subsequent '94 ZR1 was so vastly superior in every respect. So happy to have gotten rid of the '89 C4 with horrible handling and ride.
As far as the current debate on C7 Z51's... The car I'm considering right now still has the original factory window sticker
The window sticker title is "2014 Corvette Stingray Coupe w/Z51"
Down below where equipment is detailed, there are two major Subsections of equipment listings. The first major subsection is titled:
"STANDARD EQUIPMENT
Items featured below are included at no extra charge in the standard vehicle price shown"
Below that, "Z51 PERFORMANCE PACKAGE" is listed in bold print within the Standard Equipment subsection and included Z51 components are broken down in detail.
Way over on the right side of the equipment listings is the second major subsection that is titled:
"OPTIONS AND PRICING
MSRP $53,800"
Options installed by the manufacturer (May replace standard equipment shown)"
Many "options" including 3LT, Mag Ride, CF Roof, Cf dash, competition seats, bigger wheels, yellow calipers etc. etc. are all listed therein but there is zero mention of "Z51" within the options subsection.
I believe this is the official legal detailed document required by law. Z51 is included in the vehicles descriptive title and is a component of "Standard Equipment", not "Optional Equipment".
Again, I believe this is the legally controlling document. The order form does not have such status.
Call it a C7 Stingray, a Stingray, a C7 w/Z51, a C7 Z51, or even a Z51 as you choose. None are really wrong.
Conversely, the Z07 Performance Package is listed as an option within the Options subsection on the C7 Z06 window sticker. Now, do I have a problem with the owner of such a car calling it a Z07? No. Why would I?
