Thought i would post some photos of a GT1 monocoque i built for a genuine car hard work but quite simple might be of intrest
Yes Paolo
The first two photos you posted is the gt1 the third is an evo car and the fourth is the evo three and the last of the series.
also at the time of those cars the mercedes cars flipped too due to the very flat bottom, ventura were not developed to the full extent as they are today.
one day I will build myself one as i still have all the dimensions and access to body moulds for the carbon I just don't want to sell my GT40 to finance it so on the back burner at the moment
