Seen what happens without. Rads get damaged by fins being bent over. More bent the less airflow and cooling. It’s not about rocks going through.Just rethinking whether or not the screens are a must have or nice to have option. Fifty+ years of car ownership and in s**t hole locations and never installed this type of protection before and never had a rock go through the grill or radiator. starting to think maybe this is overkill/hype just because it’s a C8. .None of my Vettes ever had it.
