Help me plan my new project

[jkrueger]

So with the Roadster sold, it is time to start planning the Coupe project. The primary use for the car will be to compete in the One Lap of America race with my dad who will also be helping me build it. My Dad and I have run a V8 powered Mazda RX-7 the last 3 years in this race and have done pretty good for a couple of amateurs. So the car needs to be reasonably comfortable on the street but a fast track car as well.

This is what I got so far, but I am open to new ideas and peoples opinions. So let me know what you think.
