Z06 Constraints

I went to spec a Z06 today and the order system at the dealership wouldn't accept the order due to constraints on Z07 package and CFV. Has anyone else had a problem ordering these items? Thanks for any input.

Great news, that we have confirmation that the Z06 "ordering window" (consensus, DOSP*) will be open this Thursday!

Good luck to all in the running to get their Z06 7-speed manual trans coupe accepted.

D.O.S.P mean "dealer order submission process," and for those who haven't seen this (put together by "mjw930), here is what a Thursday through Tuesday DOSP involves. Thanks Mark.

DOSP (Dealer Order Submission Process) is the order cycle (most often weekly, but often not on new models, nor beginning of a new model year). On Thursday dealers can place orders for units allocated to them. Orders must be placed by 9PM Eastern Time Saturday.
The weekly process consists of 4 stages.

1. Constraints Distribution - Dealers are informed on constraints to review before placing orders.

2. Dealer Order Submission - Dealers can order on Thursday, Friday or no later than midnight on Saturday. (You can submit orders earlier but you don't know the contraints. A constraint is a limit placed on a specific build configuration.)

3. The 4-Pass Process - GM will attempt to place each dealers orders on Mondays using a 4-Pass process. (At this point a dealer may get more or less than was allocated if they asked.)

4. Dealer Review-You can review your placed orders for changes or replacements until Tuesday at 9pm ET. That's when the orders are sent for production.

GM moves orders from 1100 to 2000 on the Tuesday after the dealer is given that specific allocation. How quickly you move from A to B completely depends on the dealer's allocation. If the dealer had an allocation and also enough allocation for every specific constrained option when you placed the order, your order will move to at least status 2000, usually by the day after the DOSP closes. If the dealer was not yet assigned an allocation matching your order, you will continue to be at 1100 until he/she does. The length of time depends completely on allocations and your priority on that dealer's internal priority list. Of course constraints on an item that one is not willing to compromise on, also will mean remaining at status 1100.

Do you know whether the a8 transmission will be available this week? If not any idea when GM will release it?
As you asked, my best guess, and it is just that, is no sooner than November 6th, more probably around November 13th (the end of GM's previously stated "window"). Of course, if they were to meet their most optimistic schedule (also stated in their September 18th internal dealer memo), the A8/convertible ordering window could open as soon as this Thursday. However, haven't heard a single estimate or opinion from folks who have a long term excellent track record of contacts and "knowing things," that they believe it would be earlier than November 6th, and almost all are saying November 13th, with one saying maybe even after that. Sorry.
Thanks. Just hoping and waiting. FYI. I drove an A8 in a Z51 over the weekend. I was very impressed. Shifted in manual (track mode) as fast as my GTR. Knowing this has helped me endure the wait.

For those who have not yet this morning found your way to our "Constraint Updates" thread, here are today's constraints, thanks to Ryan @ GatesChevyWorld!

I assume the release of the A8 is being help up until they can get the overheating of it on the track sorted out. They want the ZO6 "track certified" and need to have all of their ducks in a row. Sorting out a car for the track is a slow and expensive proposition (been there, done that!). Location of extra coolers is not that easy, they have to consider putting them in a place that has good air flow yet is protected from ground debris be it dirt, rocks or tire "marbles" which can all clog the coolers. My understanding is that they were going to locate one on each side below the doors. That would not be the best place for air flow or avoidance of debris. Most logical place is up in the nose section but that also restricts the engine cooling. Engineers will eventually figure it out but that takes time. If they put it in the rear they really need more venting than is there at the tail lights, maybe behind the rear tire wheel well on the sides.

Not seeing 8AT in the picture, does that mean 8AT is available now?

No. If your dealer tries to enter an A8 order into the system, it will be kicked out. Some A8 orders got entered at the very beginning of the process, but Chevy subsequently changed the system to prevent A8 orders, when it became obvious that most of the Z06s were being ordered with A8 trannies. My dealer says it will remain this way until the consensus where they release the A8s.

I don't think anyone can make the assumption the delay is due to cooling.

The only thing we know is it's delayed. No one outside of the Corvette team knows why and postulating does no one any good.
Unless it is a torque issue, overheating is the only other issue. They are allowing orders of standard Stingray without any issues. I have not heard anything about track use yet so I will stick with it is either an overheating issue or torque overload.

There are dozens of things it could be, you mentioned 2.

The point is no one knows but you can be damn well sure that after everyone repeats and reposts a singular speculation it will be considered fact within days. That's one of the most frustrating things about the Internet, facts become virtually impossible to differentiate from speculation over time.

We only have one fact, the A8 for the Z06 has been delayed.

This appears to have shown up as an after thought once the ZO6 was added to the mix to handle additional thermal challenges to the diff. and trans. I have used similar add-ons in the past to ram more air into a duct for added cooling when we had overheating issues. It would look a lot better if the rear quarter panel was designed with that integrated into it.

Respectfully disagree, as the Z06 aero was in the design process when the StingRay was being designed. That "curved aero blade" was a result of tens of hours of GM's wind tunnel (largest in the world) development, testing, etc. It also initially was designed via input from GM's Cray Supercomputer and aero software systems. First aero blade was made with a 3-D printer, and after many successive re-designs as a result of wind tunnel tests, each version learning from the last one, each successive one printed in the 3-D printer, this final version was adopted. It results in, at 45 MPH, 50% more air being directed into the two rear heat exchangers than without it.

As you your comment about its visual design, or lack of it, just do not think GM cared, as they stated at the time of the Z06's release, in a subsequent video interview (and paraphrasing a little bit here), every duct, grill and vent was designed for maximum aerodynamic effect, save one, the rear fender lower air intake scoop for cooling the brakes, for that one was designed as an aesthetic as a styling cue carrying over from both the C5 Z06 and the C6 Z06.

I just think it would have a better visual flow if it was integrated into the panel itself. I'm sure it works, it did on my car 7 years ago.
