I have a slightly different question.
Back in the good old days (some time in the last couple weeks) I saw a post somewhere about someone who changed out his springs and was experimenting with different spring stiffnesses in the front and rear. He started out with something fairly even and ended up with 700# in the rear and 400# in the front (not sure if the nomenclature is correct). On a '91 325i Cabriolet, what should the spring stiffness be for good handling and a ride that is not overly harsh? Should the rears be that much stiffer than the front?
Just for comparison, what is the spring stiffness of the H&R sets (the ones that lower the car 1.25") sold with Bilstein Sport shocks on many web sites? Are these a good choice or should I go with something more custom?
