The second test day is over.
Again I am not fully satisfied, but this time I at least have a smile on my face.
As we already determined the floor and its mounts is to weak to resist and lead the forces into the suspension. At speeds of 30 km/h and above the floor pulls it self down in a way that it rubs on the ground and slows the car.
I was forced to support the skirt-part and diffuser. I couldn't use the Dodge Dart body and drove without it. The balance was shifted strongly to the rear, but I could push the car in a normal riddim which speaks for a functioning airflow under the car.
Under the shower my brain developed a new strong rubfree floor. Lexan quota will be reduced and cfk will be used more. I am still not sure if a sealed double chassis has an advantage over an normal sealed floor. The latter is much easier to implement and build.
