Well, all the parameters I was noting are what determines the rate of the finished spring; # of active coils, length, wire diameter, inside diameter, etc., you can calculate it pretty easily... that's why I was asking.

Same wire thickness and coil diameter. I think the same number of coils, just shorter spacing. The new springs are listed on a reliable Subaru info site as 257lb./in. front, 190 rear, but the rears are progressive. Like Matt said, about a 20% increase.
