Hi Chizel,

Welcome to the page, the cams manual lets you know minimum wall dimensions for tubing in construction
of the main chassis of the sports sedan. Yes you can turn a front wheel drive car into a rear wheel drive
that is no problem as long as the fwd base car used satisfies the other requirements.

The rules are being updated as i type BUT the general form of them wont change and they can be found on
the cams website

hope that helps
