Curious what STAGE 2 cooling ducts will end up looking like. I was under the impression that Stage 1 and 2 would have the narrow vertical vents in the rear, while the Stage 3 would have wider vertical vents. I guess its still up for change until the testing is complete. Also wondering if the Stage 2 will have the scoop extension on the cooling intakes for transmission and diff. Only time will tell. I only mention because I want Stage 2 with the wider vertical vents and the scoop extension on the intake. Guess we'll know for sure in 5 months. Watched the video a few times and reached this conclusion: This Z06 has the Stage 2 Aero package, the more efficient cooling scoops at the intake for tranny and diff, and the wider vertical vents in the rear. I could be wrong, as its hard to see clearly in this video. Sure hope this is the Stage 2 we get. I'm aware how engineers design. (Mechanical Eng background). If a design is adequate, no need to over design for economical reasons. In ALL cases, a minimum requirement, meets requirements. If the minimum requirement wasn't good enough, it wouldn't be the minimum. Having said all of that, a little extra cooling capacity sure would be welcome in this powerful beast, even if engineers ascertain that a Stage 2 might not require the cooling requirements of a full blown Stage 3 Racer.
