Would be interesting to see. I've worked for a Mazda dealer for the past 14 years, and there are plenty of aftermarket mesh like grilles made for the Miata and RX-8. I've seen many of them come into the shop with them installed for the same reason, protection for the radiator or A/C condensor.

JK.. Chevy brought the silver convertible to Barrett-Jackson WPB. But they refused to open the car or roll back the roof. I thought Mr Wyndham might like to see the silver with the exposed CF Hood insert. Here are a couple of pictures comparing a ZL1 grill to an SS grill.

You can see how the different shapes of the center and side grilles work in these shots: The ZL 1 has more of the side grilles ducting air to the side radiators (The Camaro has 3 radiators as explained in several magazine articles). Those side openings are much bigger and in the SS they are partially blocked. Because the the extra ~200hp additional cooling is needed.

Interesting....

Just because they are available and installed, doesn't mean they improve, or maintain cooling. Miatas and RX-8s don't put out V8-levels of heat...

That's why I'd be curious to see real test data. That mesh is very tight, which means there's a lot of frontal area compromised, limiting total airflow...or at least disturbing it before hitting the heat exchangers.

But then...Cadillac V's use a similar mesh, just wider.

Since they went to such extremes for air flow to hollow out the front bow tie emblem on the 5th gen Z/28. I would guess there's a definite reason for the grill 'mesh' to as open as it is, and adding a finer mesh to help protect things would indeed have a detrimental effect on the air flow.

Would the reduction in air flow have a measurable effect during normal driving? probably not, but it might turn into an issue if you drive your car hard where it would increase the heat the engine gives off.

I don't think I'd bother trying to second guess the engineers, and just leave the grill the way it is.

That's kind of where I'm coming from. DD? No issue...track day? yikes...

Close reading if my original post will say that my proposal suggested stretch clips on each side for easy removal (DD vs Track day). Problem was solved within post. The mesh size of openings and material could be designed for optimal balance of heat protection and road rash protection. If it makes it to production with such an obvious vulnerability GM could be opening itself up for a major recall. Just trying to help. Again, have seen this type issue arise in past and mandate dealer replacement of coils due to faulty design. It only takes a small pinhole to ruin your day.

I missed that. I wonder how such a thing would mount easily without taking the entire front clip off?

Not sayin that tight of a mesh would improve anything. Was just saying that just because it's there, doesn't necessarily mean it will hinder airflow. Of course if I was tracking a vehicle, I wouldn't be installing anything, anywhere, that didn't provide improvements.

Very nice up close. Most of the pics if not all, of the red , blue, garnet red and black had just the carbon splash and not the open weave. I wonder how much of an option this will be vs the standard carbon splash ?

[dw22racer]

Nice pics! The carbon looks really nice exposed. Top ply (First in the mold) is 45 degrees! Just another special touch on the ZL1 to keep us drooling. I'm wondering, Why order 1 when there are basically no options except color anyway? They should make the Performance data recorder standard for the price!!

Because the weave is going to be visible, when they lay the fabric, they have to take special care to make sure the weave pattern is straight throughout the insert. That extra effort is more labor, thus more cost.
If the insert is to be painted, then it doesn't matter if the weave pattern is less than perfect.

Not a scam at all.

+1 I also believe if they use the same clear as the C6 ZR1 the roof was finished with a special clear that was $60,000 a gallon.

Since when has Clear kitchen plastic wrap not been enough? Keeps my sandwich fresh. Lol
