Is the c7 convertible also limited? It also has a canvas top.... Although it is smaller being only 2 seats - maybe more stable?

I couldn't find Chevrolet's original data sheets anymore, but other online sources quoted 212 mph for the C7 coupe and 174 mph for the C7 convertible.

What's the limiter set on the LT1s?

Official specs state 149 mph, likely due to tire limitations, see below.

I haven't seen an LT1 tune yet, so I'm not sure what the hard limiter is set to, but my guess is it's probably the same 155 mph as in the vert.
