The computer model shows the completed frame coming in at 127kg (the last time I weighed it, it was about 10% less than what the model said it should have been) , the completed car I expect to way about 950kg. |
Wow, that's pretty light! I am sure it will be a very stiff and safe chassis. I just don't think I have ever seen a car with that much diagonal bracing on a tube frame. Not questioning your knowledge, I wouldn't be able to get the floor ladder done on my own! Cool project.
