As I mentioned I did my first full on track day back in September. For this event I had the Z/28 brake ducts installed. While these work well in removing heat from the brakes, I believe that the Quantums probably are better at focusing cool air to the rotors. I decided to integrate the Quantums without giving up the Z/28 ducts, increasing overall cooling vs. with one or the other. I have no data to support this, but future track days will either support this move or not.
The continued use of the Z/28 ducts present a challenge in routing the 3" duct tubing, which resulted in me removing my windshield washer reservoir. For me, this is acceptable as I choose to drive my Camaro on dry days from the late spring to early autumn for which I rarely would use the washer.
I have only done the driver's side, but preliminary observations of the passenger side show that the coolant reservoir make present some routing issues also.

Some pics:
My duct inlet for the Quantums use the fog light bezel. Yes, I have read what others have stated that GM says this area is not optimum for an inlet. I looked at the Stevenson Z/28.R front fascia and they are utilizing the fog light area. I understand there are other variables at play here, but how bad can it be?
Here you can see both the Z/28 duct inlet and the inlet for the Quantums
