The spring rates for the SVE Mustang lowering springs are 571 LB/IN Linear Rate* for the front spring and 200/251 LB/IN Progressive Rate for the rear springs.
*Why a Linear Rate in the Front? Because the movement cycle of the front springs is in an arc, a linear spring behaves like a progressive spring in the front of a 79-04 Mustang.
