Great "what's in the trunk" from rlarsen462 here:

The dealer threw in # 84669205 duct kit for the ZL1 1LE since they knew I would track the car. Decent of them. Installation instructions in the PDF.
The instructions say to remove the fasteners from the back of the front air deflector (handles air from the trans cooler) to facilitate removal of the front bolt on the noise shields. I used a dremel to open up the area around the bolt to make removal/install easier. The car is a DD, so I don't plan to keep the cooling ducts on, I'll put them on during normal track prep.
A curious thing: the shield supports are marked L&R, but they are marked backwards. So the left one goes on the right side of the car and vice versa.
