Going to be doing getting a C7 Z51 here soon, 2014 or '15. If I find coolant is hot on track is the aux radiator an option? Or is that Z06 only?

It would probably work, but a Dewitts radiator might work better and cheaper (maybe)

Car has powertrain warranty through 5/19. Don't want to give GM any outs.

I under stand although check that out with your dealer.
In the past GM parts installed by the dealer did not affect warranty, However lately I have heard of claims being turned down because the parts were not original to that car ie Z06 parts on a base car
