it bugs me when people say the dont have the tools to make their own parts. the simple fact is that you dont need a cnc machine, plasma cutter, tig welder and all this really expensive equipment to make your own parts. its likely not the tools you lack, its the creativity. i can give you very simple designs for shock towers that only require a drill with bits, a pair of metal shears (aka tin snips) and a file to smooth the edges. i am presently designing a custom chassis with suspension that can be made with a drill, vise (even vise grips will work) an angle grinder (most of us have a dremel which will work just as well, albeit slower), misc. hardware and ~$30 worth of steel strip (1/8"x1/2" and 1/8"x3/4"). i am not using any expensive cad program either, i am using the free version of google scetchup 8.
