I've always thought it'd be cool to build one of these from scratch, not to the F1 level, but good enough to actually race with. I've seen people make chassies and drop in the busa motor, run auto-x and win. I was thinking of building from scratch(aluminum), but was wondering if anybody done this kind of thing before. How hard can it be? What do I need to fabricate a complete racing car to meet organization standards? What clubs do I need to look into for this kind of racing? I've beern wanting to get into racing whether it's motoGP or this sorta thing. I suppose something like this is closer to the F3 cars then F1, but you get the idea. Here's some sample pictures to show what I'm talking about:
