    not worth doing much on a road car. the welding is easy but stripping and cleaning every seam is not. renault also fitted a set of strengthening plates on the weakest sections so if your doing it i would suggest making these up as well.

    every seam in about one inch weld leave an inch.

    don,t think the cups had any...

    yeah they the rally car ones but they used exactly the same set up for tarmac but with stiffer rates larger brakes and larger tyres.

    what about rivveting pannels together to save buying a welder, it will not be as strong but it has to help

    if you were riveting it i wouldnt bother in the first place.

    Cups - only mods they had were the bungs in the floor removed. The roll cage gave as much strengthening as they needed.

    i was going to weld it but i dont have one, busses are held together with rivvets, thats what gave me the idea, a rivvet inbetween every spot weld must strenghten things up?

    id say not to bother.

    a rollcage will give the extra stiffness required.

    welding the seams will take a LOT of effort to clean the seam properly in the first place and then it requires someone competant to do the welding.

    most home/diy welding is done with stick (arc mma) welding, which generates a lot of heat, and generally wont look very good. the best option would be using a mig welder with a heavy argonsheild gas. not very cheap!!

    ohh and the next thing is u cant just pick up a welder and do it. ive been learning for around a year or so and do it regularly at work too and still would not regard myself as a GOOD welder! generally when you are learning in the first few weeks, 90% of the welds created will either break or are not joining the required metal.

    definatley something to try your hand at by all means, but id recommend not learning by seam welding a chassis.
