OK Gunkk, thanks a lot for the confirmation.
Of course, in the past, the top speed limiters were often put in place to not exceed tire speed ratings.
I made a detour over to Tire Rack to check out what the speed ratings of the OEM tires were for the Camaro, which are the same for the Coupe and Vert.
It was a learning experience to see what a "hack" that the top level speed rating of above 186 MPH had become, with "Z" really denoting "over 149 MPH" and then "W" (168 MPH), "Y" (186 MPH), or "(Y)" (above 186 MPH) being added at the end of the rating. What a mess.
Suffice to say a limit of 155 for the ZL1 Vert was not put in place because of tire limitations of the Goodyear Eagle F1 Supercar tires.
