Corvette does not owe you any particular insight into its plans or issues. For the life of me I do not understand why you are still here. If GM is so bad in your eyes, why not dump the vette and go pester some other brand? You've never said anything positive in all your many incarnations, jut a Negative Nelly who has zero solutions. It's tiresome. Ignored.

Thank you very much for writing down all this info!
I am a bit confused regarding spring rates:
Looks like on some cars, the front can be in 500s while rear can get to 900+ lbs/in spring rate? I've never heard of 900+ rates on a stock Corvette. Moreover, I've never heard of much-higher rear spring rates on a GT car (front engine), either.
FYI, my LG G2 coilovers are produced at 750 lbs/in front, 700 lbs/in rear, at 1.07:1 ratio, incidentally identical to Z07 ratio, which is the only one that is higher at front.

Granted, legally and confidentially they can't talk about certain things.
If they said a part was bad, it would need to be recalled. The problem is two fold, one people ask questions they know can't be answered. Two, the GM people "try to answer" them without sounding like jerks, but still sound like jerks.
It's sometimes just easier to not ask the question.

Since my question about how they plan to deal with intake valve coking wasn't included and that they claim a catch can isn't needed indicates that they are officially in denial.

Thanks Jeremy for this effort.
I'm a little surprised that they could not find an 'appealing' solution to including a 'blind spot' mirror(s). I suspect it has more to do with economics. My DD '14 Taurus has them and are nice although not actually required if the mirror are adjusted properly. With my C7's mirrors a little smaller than the Taurus I can understand how some would like to have them on a C7, even properly adjusted. Me included.

They are it's obvious by the statements made. They must think the customer is really stupid. I'm sure they have grown to hate these forums because they showcase the mistakes and engineering flaws they make.

The forum members here hold GM's engineers feet to the fire pretty good. I think that is a plus for consumers. Overall they eventually have to respond one way or the other. One of the greatest benefits of the Internet is that consumers now have a huge advantage over the way it was before the Internet. There was no way we could communicate effectively with each other as consumers and users before. Overall I it has forced companies to upgrade their production and service quality. They know that they are now held accountable for their products and services. If they perform poorly it is immediately broadcasted throughout the Internet. How they deal with this also paints a picture of what they really are at their core. No more pulling the wool over consumers eyes.

This Forum has several avenues of contact with Corvette Engineers. This opportunity was one of them and no one asked that specific question.
We have regular "Ask Tadge" opportunities where that specific question can be formulated and voted on by the membership. Tadge has been sincere in response to all of the questions asked of him. The question must be constructed in a manner so as not to be threatening of condescending, but respectful of his position and the opportunity he extends to us.

I readjusted my Jeep mirrors to the SAE recommendation which resulted in no blind spots. It's takes a lot of getting use to!!

If the C7 mirror were made larger to accommodate a blind-side mirror, it would spoil the aerodynamics of the car. The Corvette, after all, is designed for performance, not frivolous add-ons in the production version.
If you want truck sized mirrors, add them after you take the car home.

Were it available, an actual text of the Q & A session, or even a video tape would really be helpful, as regards to the completeness of the actual dialogue that took place. So as not to misinterpret the event, in terms of actual words spoken. Thanks!

While the mirrors address most of the situations, the added reassurance of the BSA is very nice to have. One of the situations which happened this past week was while changing lanes, my mirrors told me no one was there and as I came over, BSA started beeping (WTF!!!), I look in my mirror and some tool bag is trying to come over from the 3rd lane. I quickly went back in my lane and all is good now.
I love my C250, lots of little goodies in the car, but BSA is probably my favorite option (along with the suede seats)

The two pictures of rear view mirrors are misleading. As CrabbyJ stated, the C7 mirrors are smaller than the Taurus mirrors shown in the comparison. The C7 mirrors are smaller than C6 and take some time to be accustomed to when driving. If a blind side mirror were added to the existing size, it would take away essential regular mirror real-estate and be too small to be of any value.
If the C7 mirror were made larger to accommodate a blind-side mirror, it would spoil the aerodynamics of the car. The Corvette, after all, is designed for performance, not frivolous add-ons in the production version.
If you want truck sized mirrors, add them after you take the car home.

I believe this is how MB does it now. For my 2013 C250 coupe, it is on the mirror and not in the dash (at least I don't think it is displayed since I usually only track travel time)

- Automatic PDR operation option
TEAM MEMBER COMMENT - The main issue with this is the legal ramifications of recording audio of someone in the car without that person knowing they are being recorded.
TEAM MEMBER COMMENT - The main issue with this is the legal ramifications of recording audio of someone in the car without that person knowing they are being recorded.
Before my offering of the phrasing of the followup question I'd like to be asked....
recording a person without consent:
a. if the person isn't in view of the camera (not in the frame) is there still a "legal ramification"?
Yes, but only because the audio is being recorded as well.
b. if the person isn't in view of the camera (not in the frame), and the audio has been disabled in this "auto-record" mode.... is there still a "legal ramification"?
No
It seems the answers to these PDR questions are often skirted around.
If auto-record automatically squelches the audio recording... then the legalities become moot.
I am seriously thinking that since GM contracted the PDR software out, they would have to pay Cosworth to add this "legal" auto-record mode... (GM probably doesn't own the source code, couldn't do it in-house anyways)...and they just don't want to spend the money. And that's fine if it's the case. I just wish we'd get a straight answer.
I know some are thinking this shouldn't be a big deal; but hey... I'm just trying to get some use out of a system that was bundled with the NAV system (like many, I wanted the $800 NAV option initially; not the PDR. Months after the order was accepted, then to be told it's changed, now to include the PDR... new price of both combined: $1700).
If it had a traffic cam auto-record mode (which I could use)... it would be a lot easier to swallow the $1700 price paid.
My suggestion for asking this question again:
"PDR; can an auto-record mode be added, understanding that it won't record the audio portion while operating in this mode... thus negating any of the legal concerns?"

One question I forgot to include for your visit, which I hope you can find an answer to is:
What is the part # for the new transparent roof top for coupes built from late 2015 onward and when will they be available to purchase? These are supposed to have the new hardware to eliminate noise issues on the earlier version.

will those that have access to asking these questions directly... please ask more specifically?

For everyone else there is understeer and body roll to keep things cushy and safe. I'm sure the GS is easier to drive but I also think it left some performance on the table by not getting the stiffer front leaf.

I am not surprised. To me, the only Corvette ever produced with high enough springs rates is the Z06 Z07. It's totally worth the cost just for that. Even the Grand Sport gets the soft front spring rate.
For everyone else there is understeer and body roll to keep things cushy and safe. I'm sure the GS is easier to drive but I also think it left some performance on the table by not getting the stiffer front leaf.

I've tried my Z51 with stock FE3 springs but with T1 shocks and 315 front tires today; it leaned a bit too much at the track, felt a bit like boat and it seems tires went up as much as 3"(!) towards fender, rubbing its inside. In short, traction overwhelmed the setup, especially up front. It felt like it needed twice the spring rate. Anyway, will try the coilovers next week : )
I will always wonder how a proper setup with a good set of coilovers compare to magnetic (Z07); it becomes hard to guess. People made big gains when they switched to coilovers from C6 Z07, but C7 config might be better.
