BN1 Ride height

There is about 7/8" difference in the frame clearance under my car--front is 
about 6-1/2" and rear is 5-3/4".  I assume that this is due to the leaf 
springs' sagging.  I've heard that springs can be re-arched but is this the 
best way 
to go?  Seems like a remember discussions on this topic with negative 
comments about aftermarket spring quality.  Comments please?
