I purchased a new 2019 GS convertible a few weeks ago. The brake cooling ducts were in the trunk. I called the dealer service dept and they said they are only needed if you intend to track the car. Is that true? I seem to recall a video that Tadge was in that stated the ducts were meant to be installed by the dealer and did not specify for track only.

Sounds to me lie the dealer didn't want to bother. Good thing the engine wasn't tossed in the rear, too (oh wait... that's the C8 ).

My dealer said the same thing when I bought my ZR1........the install is not too hard. You don’t need them unless you are going run on the track.

They are not to be installed if you are not going to track the car. Tadge said depending on driving conditions the ducts could prematurely wear the brakes.
If you are not going to track the car I do not think it is necessary, there are deflectors to cool the brakes as standard.

I put mine on using a lift and it is a bit of a jig saw puzzle.

Thanks for the responses, I'll just leave them in the plastic bag.

Are they the same or similar ducts as are found on the Z51 package? How would more air to the brakes prematurely wear them?

Brakes are like engine oil, they need a certain amount of heat to work properly. There is such a thing as over-cooling a system.

The added brake ducts hang low under the car and can scoop grit and water into the brake rotors which will cause added wear. My 18 came with them in a bag. My 19 came with them installed, which was a mistake from the factory, but I don't care.
