I have the chance to pick up a Miata dirt cheap and was thinking about turning it into a Spec racer, but I'm a big guy. I would fit if I could gut the drivers door and put the door bars in there like my ITS car. Is this legal for Spec-Miata? Also do you have to buy a bolt in cage, or can you build and WELD your own in?
