Rolling Space frame chassis wanted

I am planning to build a car with the Sports Sedan rules in mind to use as a track day car.
I prefer to get it as a Rolling chassis want to build it as a 2 doors coupe

Thanks mate. Am working on the mechanical package currently. As The 4.5 V8 capacity rules look quite a pealing to me.
Still contemplating which bodywork to take might be European or Japan.
Not sure yet.
