Relax lol and at the same time. I've had my Z coupe upto 160 stock. Here's my question, on a Z vert would the Pillars be able to hold up to that kind of stress from all the air pressure against the front glass?

From a safety point though and whether or not the top is up, you guys roll that thing at higher speeds you have no chance of walking away. Albeit rolling it at 155 I still don't know if one could walk away. Personally and in my own opinion I think it was a good call by GM to limit the vert to that.

Back on topic though, and seriously a concern, at what speed with the convertible top just peel itself away from the car or possibly be damaged in some way?

That is where the limiter used to kick in on my bike. Installed a timing retard eliminator. Now HP is the limit.

155 1/2.

I ran a 97 SS vert -Mods mainly was engine and suspension- back in 1999 to 170 mph (I stayed on that speed for a whole minute, don't ask me where I did this), the air pressure sounds around the front wind shield was the main reason I didn't go further, after that run I didn't have any structure damage to the top.
Which makes me think that C5 vert should have a better structural integrity than C4 vert, since it's 15 years later..
Otherwise if its the same I would say don't go over 160 mph in a vert because the sounds alone are scary enough.

I'm guessing either the flats on 95 or that section way out west on 90?

No, I was somewhere in Utah, leaving it at that (was a road trip from L.A. to Boston).

I'm itching to do that again.

So I would need a tune. Thanks to those that answered my question.
thanks to the rest who added info or entertainment!

Are you saying the coupe is set to 202? I wonder what the stated need for that is? Of course, why would anyone in coupe want to go faster than 202?
