Thanks John! That's great luck, with a dash of smarts being thrown in!

Understand about splitters and skirts....the video on YouTube (Tadge talking about Z06 aerodynamics posted last week) gives a very good look at stage 1 aero....from that, splitter appears to me (unfortunately) to look like same material as splash guards are made of.

I would be curious if you could find out about the attachment points/methods for the stage one spoiler versus the stage2/3 one....as many of us "constrained" into stage 1 would like to upgrade after the fact to the stage 2/3 spoiler....does it attach at the same points, or are different holes required? Do either use double sided adhesive? IN other words - what's involved in removing stage one spoiler and replacing with stage 2/3?

Think you have nailed the reason "Redc7!"

Forget the specifics, but they actually had to rethink the covers for the Stingray Convertibles due to wind flapping/paint scratching from lack of the fastback coupe roof. Rick Conti told me he spoke with Steve Grilli about it directly right after he received his first convertible, and they ended up (I think...getting old & forgetful) putting foam or something on the rear deckled under the cover to protect....

More 11/10 Z06 BGAP info:

1) Spoiler:

Have to possibly backtrack from my earlier statements that the Stage 1 spoiler is exactly the same as the Z-51's except wider.

Reason: None of the spoilers vertical plates are now being attached during the assembly process. They were, but recently are no longer... Perhaps this was for easier assembly of other parts, or perhaps to prevent scratches or abrasions during either assembly or transport.

Thus, today during all three tours, every spoiler, when viewed from the back has a series of about nine "receiving bolt" holes for the vertical spoiler plates.

Hence, when I was viewing them from a frontal point of view, they do look exactly like Z-51 spoilers, but as no vertical plates were present, nor as of yet the right person to ask, just do not know definitive info about the Stage 1's spoiler yet.

Another possibility, though very unlikely, is that they were only running Z06's today with either the CFZ or CFZ option???

Will try and learn more as soon as possible...

John - hoping you see this before your buyer's tour....I had a crazy thought regarding the spoilers...

What if EVERY Z06 had the same spoiler piece mounted to the car, with the differences being the wickerbills/vertical plates which would bolt to it??This would allow GM to manufacture using one base piece & a single assembly process, and then ship differing pieces to the dealer for attachment at PDI depending on the aero level ordered? This would mean going from a stage one spoiler to a stage 2 or stage 3 would be as simple as removing the existing wicker bills, and attaching the different ones using the same holes on the "base" of the spoiler. A *BIG* help to this of us constrained into stage 1 aero but wanted stage 2....

I will post screen captures from the recent "aero" video in support of this.....

 

[ALF01]

The white car is a stage 2, the gray is a stage 1 aero car. Note the similarities in the "base" piece of the spoiler and the seemingly identical mounting points between the different vertical plates/wickerbills....

 

[ALF01]

Another benefit of this "standard base piece" approach is for those who have ordered dual racing stripes on their car.....since the stripes go over the spoiler - with this set up, you could keep the base piece with the stripes on it rather than being faced with having to "re-stripe" a new spoiler.....

 

[ALF01]

John...why would I be disappointed? Sounds like it will provide all aero levels all options, no?

Thanks for sharing all the great information!

Agreed, this (to me) is GREAT NEWS for my stage 1 car...I can upgrade without having to remove the base piece.

Just finished the last tour of the day, and once again no Spectra Gray wheels. That makes six tours, and only one Z06 with Spectra Gray wheels -- inspite of my seeing about 80 Z06's in total. This is certainly different from what I have heard from two of the top five dealers who have lots of Spectra Gray orders, mine is Spectra Gray, as are two of my friend's. Maybe just coincidence, with tomorrow or the rest of the week running a fair amount of them?

After 6 tours, have you taken to politely correcting the guides when their info is wrong?

 

[ALF01]

Is ALF01 correct about his original post that the spoilers wickerbills could possibly be interchangeable? I'm confused because "elegant" wrote stage 1 people would be disappointed. Reading further in the thread didn't clear anything up for me.

Elegant (aka John) clarified as follows:

Yes, the base is a standard piece on ALL Z06's, with different wicker bills.
The "disappointed comment" was in reference to those who ordered stage 1 aero hoping it would not have wicker bills at all.....but many of us (myself included) are very happy about how this played out, as we were hoping for stage 2 aero were but "constrained out" of it....we now know the spoiler will be easily upgraded.

 

[ALF01]

Dave, it seems to me that the side "wrap around" pieces, as you called them, are part of the vertical plates which bolt onto the spoiler. On other words, the vertical plates are bent on the outside edge of the car 90 degrees forward.

In time, hopefully we will see these plates not on a car and know for sure.

Also, I am wondering what it would look like if a Stage 1 had the vertical plates removed, and then just replace the bolts in the holes without a plate installed. I wonder if that would look similar enough to the Z51-style spoiler, or if the bolts inserted by themselves would look tacky.

I believe this is, in essence, correct....the wrap around edge is part of the bolt on wicker bill & not the base spoiler piece....

 

[ALF01]

This was in a thread by ZeeshanFarooq29, where he stated that this was a prototype of the stage 1 (spoiler only). You would have to ask him for any more details.

There is a video on YouTube - search for "Z06 most aerodynamic Corvette ever"...came out about a week ago, less than 2 minutes long.

The video clearly shows a stage 1 splitter and spoiler on a gray car....I have posted captures previously. The stage 1 spoiler (as I recall) does not have any wrap around, just vertical wicker bills that slightly rise above the base piece. See post #29 in this thread.....

BGAP Z06 Update:1st Z06 Completed.

Or, "luck beats the heck out of brains anytime," for just happened to be in the right place at the right time as per below...

The line was not moving at 6:12 AM start of shift this morning, after Friday's frame-shop robot wiring failure, but did start at 8:46 AM. Z06's continued to move toward the finish line, with VIN 001, Rick Hendrick's black Z06 being the first one (no surprise) and it came off the line at 9:26 AM. Happened to luckily be at that exact spot as part of my public tour. Jeff LaMarche and other top BGAP Plant staff were there for photographs, etc.


The production rate continues to be just under 7 Z06's per hour. Saw a rainbow of colors, in fact can not think of a color of Z06 that I did not see.

In response to earlier-asked questions, splitter and skirts are not attached prior to the dealership PDI, so can not determine the specific appearance of the Stage 1 splitter. As noted earlier, EVERY Z06 spoiler is carbon flash metallic, regardless of whether it is a Stage 1, 2 or Z07 and regardless of whether one selects CFZ or CFZ.

GM Authority has an article this morning referring to this forum, and this thread...Congrats John!

That brings up an interesting question:

When testing for fuel efficiency standards on the Z06, which "stage" model was sent for testing? My guess would be stage 1.

I know it wouldn't happen, but wouldn't it be funny (or not for some), if the Stage 1 didn't have a gas guzzler tax, but the Stage 2 and/or 3 did?

Fuel efficiency testing is done based on the engine type only, right?

I wondered this myself, davem - what aero package would be used for MPG/GGT testing?

 

[ALF01]

A couple of upcoming cautions in terms of Z06 production later this month and early December.

First, already the Plant will be totally closed for two production days during Thanksgiving week, and the remaining three days, they will be running eight hours per day instead of 10. Second, for those who are calculating as to their Buyers Tour, please all be aware that December 3rd and 4th are "no public" days, meaning no visitors -- not even those who have a Buyers Tour nor Museum Delivery will be allowed into the plant, only GM employees. Please consider this before you buy your airline tickets, for if your car/Buyers Tour starts in Tuesday, December 2nd, your car will keep going down the line to completion on the 3rd/4th, days while you will be shut out of the Plant and not be able to watch that happen.

John - I'm in exactly that situation. Have been told (preliminarily) by Shane that my tour would start at 3pm on Monday 12/01, finishing about the same time on Tuesday....if it slips, it will be done "in the shadows" on Wednesday. Given how your start time shifted repeatedly, I am currently planning on going but will make a "final" decision the day before Thanksgiving - hopefully the NCM will be understanding. Fortunately, I drive there (12 hours each way) so no airline tickets in the equation.

A buyer on another forum posted the email he got from Shane saying his car started on Tuesday, finish Wednesday; and did he want to go for just Tuesday or get a refund.....

Enjoy your day tomorrow! Please post any end of line pics taken by your guide!

AWESOME John!!!
Funny....I just checked w/Chevy Chat. Still 3300 no TPW. NCM says my cars build starts in ONE WEEK!
Go figure.

Rick

Rick - NCM info much more accurate than chat....
