Back of the envelope calc, assuming a high motion ratio from a strut coil-over spring:

Using a typical OE spring rate of around 125lb/in, an increase of 40 lbs per side equals a changed in loaded spring length = 0.32". Which means ride height will drop approximately 0.32".

A "performance" spring of say, 300lb/in would see a loaded length change = 0.14" with that same 40lb/side weight gain.
