I've read lots of threads on people lowering their cars and making handling improvements, but nowhere have I heard mention of upgrading the springs to handle more weight. I have a customer that is planning a trip to Baja and is going to be carrying a considerable amount of fuel with him. So far the idea's we've explored are:
1) some type of overload or air shocks
2) Having a heavier set of springs made
3) Possible swapping some springs from another body (126)
4) Fitment of self leveling system from a wagon (or 126)

The main issue is time, he is leaving in a few weeks, so we don't have much engineering time. Any ideas you may have are greatly appreciated.

I would use the heaviest rear springs that would fit that car with the thickest spring pads.

Over here in Europe you can buy taxi springs which give you that middle eastern look!

They also do lots of heavy duty versions
