? can't you have correctly designed progressive rate springs? that don't 
bind from the weight of the car?

i've had several a1 designed springs that sat loose in the perch--if you 
lower the car at all with a higher spring weight, they *can't* be tight.  i 
think the purpose of the tight coils is that they compress easier than the 
loose coils, so you get a progressive weight. non-progressive weight 
lowering springs don't have the loose coild.
