I was thinking about replacing the front subframe of my Volvo with a tube frame to open up more engine swap and suspension possibilities. Are there any good forums for info on doing this? Anyone know of some good books for designing frames? Should I just start reading on the Locost forum?
Find a circle tracker to hang around with. Or just look at a couple of the mags. Plenty of options out there, if you keep an open mind. Attend a "racers auction" after the end of the season. There are some deals to be had on the cheap, for 'obsolete' chassis. We once picked up an entire tube chassis and cage, with all of the suspension, for under $400.
They make custom front subframes for older chevys...Camaros, Novas, etc.
They are bolt on. You might get some ideas researching that.
