What are the differences between the donor car chassis and a tube chassis?
A tube chassis is custom built using the exact measurements from the original car. The tube chassis is an identical clone of the original, because we can build the replica without any limitations. The donor cars are slightly different in the dimensions to the original car specifications. Those differences could be the positioning of the wheel axles and the width could vary partially. Also the cockpit of the donor car maybe a different size. These discrepancies are not really noticeable.
