I have found a safe place to run my Z06 up to 140-150 speeds. When I am up above 140 I get the wind noise blast of air on my window side as the speed pulls a crack open. My friend does not in the same conditions. BTW our vettes sound like jet airliners at that speed with the air slipping over them. I have read that GM tells their service techs to put silicon caulk under the weather strip. Any tips on that or will bending that little metal glass stop usually fix the problem if I push it more. Any help appreciated.... staying under 140 not an option.
