I had the earlier predecessor to those tires, Falken's ZE512s on my 2000 Z28 for a while in the mid 2000s.
They were not too horrific in the dry, or the warm wet, but were useless (at least on that ride) in even a sixteenth of an inch of snow, and forget about any ice at all!
On top of that, almost all of them developed large side wall bubbles, and this was on 245/50-16 tires which did not even see too many bad road crater/pothole impacts, and were always inflated either to specs, or slightly above.
Granted, this was 3 (or 4??) generations of Ziex before the ones you got (and they might have improved drastically), but I personally would still steer clear of their non-200 tread wear, non-performance tires altogether due to my experiences with their all season offerings.
