Rear Brake Cooling

I've thought about trying to install the stock non-track front air deflectors onto the rear control arms to improve brake cooling, but haven't done it. Just came across this article showing the C8 Z51s add on track rear brake scoops. https://www.hotrod.com/articles/did-...-prep-for-c8s/
Do want, now if I could only find the part number.

10) RH 84721515, LH 84704301
11) 11561871, need 12
12) I can't find a number or quantity
13) RH 84781212, LH 84781211
14) 11609465, need 12
15) RH 84721514, LH 84704300
16) 93360989, need 6

It'd be interesting to see someone try this

Interesting idea, for sure. Have you actually found a need? The rears seem to do “OK” to me. Maybe a modified rotor shield?

Absolute need? No, but i do get brake fade and more brake cooling is always a great idea. When even the rear wheels are too hot to touch coming off the track, that tells me brake cooling would be worth it.
Edit: I've already modified my rear rotor shield and cut away everywhere it's not beside a suspension bushing.

Speculation here:
If it says 'discontinued', it most likely has gone through an engineering change and there is a new part number. The C8 is very new and things like this will occur. Call your favorite dealer parts guy and ask for those numbers & he should be able to see the new number or tell you if they are currently on hold. His system is much better than mine.

Due to the COVID 19 mess, i have only driven the 6th gen one track weekend so I don't know how much the stabilitrak uses the rear brakes. I would think that additional cooling couldn't hurt

Thank you, I will see what I can find out.

Turn that stabilitrak off as soon as you are comfortable with tracking the car as it does use the rear brakes. Lucky that you have gotten out once this year, I haven't been able to get out yet.

You don't have to cut into the car?? according to the description you need to only drill 3 holes to bolt this on in place of the factory piece the is removable. also looking at the other pictures it looks like it also comes with ducting to direct air to the brakes

Edit: it does say some trimming required farther down on the site.

Looking again i do see how the additional ducting does make the necessary bends to go around the wheel to the brakes, but I only see that working with stock SS wheels. 1LE/ZL1 wheels are already almost touching the fender liner so there is absolutely no room for this ducting. Plus the things i said before, make that a horrible option IMO.
