I did 155 is a Z28 convertible (top up), and held it for a minute before bringing it back down. I did it on a long lonely stretch of desert highway at 5:30 AM, and I let a little bit of air out of the tires before i did it (to make sure they didn’t overheat and blow).

I was surprised it would do that, I thought it was supposed to have a speed regulator - but it was a manual, so maybe the regulator is only present on a automatic tranny.

I’m never, EVER doing that again!

Actually, you should have done the opposite and added a few more pounds of pressure to the tires before making the high speed run.
