I have a glass fibre car with a rotten mild steel space frame chassis. Is it feasible to replace (partially replace) with your carbon fibre tubes and sections? I mean would they be strong enough. The main rust is in the main backbone chassis and the sections that come out along the sills. If i have a 1inch mild steel tube section what would i replace that with for same strength?

I would replace complete section for instance the whole backbone not just patch up the rusty bit.

I have actually built a carbon framed Caterham chassis which we installed a 300 HP Cosworth race engine into, this was designed by an extremely competent team of people and took a few years from design to completion. I forget the numbers now but we did put it on the test track and it was scary quick with an incredibly stiff chassis. I certainly do not recommend doing this at home and certainly not putting it on the road and I think the law will require the car to have an IVA test should you wish to make it road legal again.
