Default Z51 J55 Brake Ducts

My new C8 came with brake ducts lying in the trunk. My dealer said they were for the front and only for track use. Is there any truth to this? I read somewhere else the ducts were for the rear.
Any clarification would be helpful. Thanks

Fronta need to be installed. The backs do not get installed. Only for track.Go back to dealer. They're paid to be installed.

My guess is the "DEALER" does not know front from back.

Anyone out there run the rear ducts on the street (against Chevrolet’s recommendation)?

Not a good idea as they hang down and are likely to a) catch on road debris and be damaged or torn off, b) have flammable debris such as leaves get caught in them and start a fire, which has already happened at least once I know of.
