[ASKED] Impact of leaving the ZR1 track cooling items installed on the street
The C7 Z06 and the C7 ZR1 both come with secondary brake cooling ducts that the owner's manual states should be installed for track use and should be removed for street use. Additionally, the C7 ZR1 comes with exhaust cooling hardware that attaches to the tunnel plate and the owner's manual also recommends removing after the track event.
What are the risks associated with leaving this equipment in place during street operation?

In either event it would be very helpful if we could get Tadge to give us his answer on this. If all we are looking at is some premature corrosion I'd accept that and leave them in place.

I’m interested to see an actual photo of the underside of the ZR1 to see what the new cooling hardware looks like. The diagram doesn’t seem to show it too well.

Thanks for the pics! Very interesting thinking about how these would work. Almost looks like it is blocking off the breather holes which you would think would make the exhaust run hotter!

The idea here is that the air surrounding the cats and exhaust pipes will get so hot while at WOT on the track that GM probably wants that out of the tunnel plate instead of going all the way back and cooking the exterior of the mufflers.
Just a guess. As to why GM suggests removing them for street driving, I'd expect it to be a ground clearance concern. But maybe we'll find out more if this gets submitted next week.

Amateur aero guy here: my guess is that the deflectors are to help get the air out of the tunnel plate as quickly as possible until it gets to the very rear of the plate. It looks like any air coming through the tunnel plate will follow the holes out from under the plate given the aero disturbance the deflectors are causing: creating a slightly lower pressure "bubble", for lack of a better word, right under those holes.

I do hope that we might eventually get a better understanding of how these alterations work... and an explanation on why GM recommends removing them for street driving. I don't think ground clearance is the issue as they have SO LITTLE impact on clearance that it just doesn't appear to be the issue... at least not to my eye.
Hoping Tadge takes this up as a questions to answer for us.

It looks like the additional tunnel hardware is to create a "Bernoulli effect", the scoops in the middle create a low pressure zone in the front of the tunnel and the block-off plates ensure that cooling air enters the front of the tunnel for max cooling effect. Based on my observation of the brake cooling system on my Z51, which puts a lot of sand inside my wheels, my guess as to why the cooling hardware is to be removed for street use is that the ZR1 would be an expensive street cleaner.

I just installed the chinese puzzle known as the extra z06 cooling ducts. Basically, they're very susceptible to getting knocked off/broken. Not exactly a very rigidly mounted piece. It's not ike you're gonna overcool your rotors.

We're actually not talking about those rings. We're specifically talking about the ducting that comes with the ZR1; that car doesn't come with the cooling rings.
