I have had a bad experience with re-arched springs. 12 months later
they had gone so soft that the car was no longer capable of being
pushed hard.
I went to a local spring maker and had a new set made up.
I gave him the old set, told him old ride height, desired ride height and he
got to it.
Since good quality spring leaves are no longer available in the same
thickness for the 1.5" width. He ended up using 4mm thick leaves.
I have had these springs for a few years now. They are terriffic, top
quality
and as a bonus they were cheaper than the UK (made with chinese steel)
replacement items.
So, my advice is to go and speak to a spring maker. I found mine by
talking to an engineering supply shop but the yellow pages will probably
suffice.
