That's why my 'designing style' for this chassis was something like 'let some doors opened' to continue the work in other directions after taking some key design decisions in some points. I had all the ideas finally made real in my mind from the beginning, but I could not face their design challenges all together. The way I designed this chassis can be observed in the evolution of my publications in thingiverse. Also all the parts are a little over-sized to be as strong as possible, but maybe this makes the car a little heavy too. This will make the car to roll over if you turn close at high speeds. The main goal this time is to have a great clearance, so the center of gravity is also higher.
