We did run a few laps, main issue was the Holden has pretty major braking issues without ABS. Its also a little down in power but with no brake balance control I was locking rears pretty hard in that and hardly put in a decent lap with it as it needed more skills then I had to keep up with the Cobra. As you can see by the lap consistency we were just mucking around a little and so its not a great benchmark, also I think I ran default setup which is street tyres so on the semi slicks it should be quite a bit better.
