Eric, I think those are Firestones, and they seem ok, Avons would be better
Cliff, hard question since the SPF has so much more power. The SPF seems more the race car as would be expected, the CAV quieter. I am partial to MK1's as far as looks goes. As I drive the CAV more again I will be able to expound on that question.
Pat, the shifter is much better. I need to fine tune the webers as I am getting some popping and lag around 2700, typical of webers. I enjoy that part however.
