Why not?? With a bit wider track and the 3.8 with coil-overs from the factory and GT3 seats (as an option). 400HP and light it would be able to keep up with the Z06 and would fit into the same GT class. That is how they could create racing lineage in witch Porsche has always been proud of.
I do not wish death for the 911 but just pointing out that Porsche does now have a better platform.
