Anyone replace the springs of a Nobsound footer?


I purchased two pairs of Nobsound spring footers to place under my REL S/812 subs.  The front of the sub is much heavier than the rear of the sub, so the two Nobsound footers under the front of the sub, with all seven springs installed, are compressed nearly 90%-95% (rather than the 50% that I understand is optimal).  I’d like to purchase some stiffer springs to see if this will work better.  
Have you purchased any other springs that were different in stiffness than the springs that come with the footers?  If so, where did you find them?

in advance, thanks!

Might be easier to just put 2 nobosounds under each corner.  I'm a physicist and have worked a lot with spring constants and it is hard to figure out what springs to buy without buying a lot and trying them. 

If you want to experiment go to an auto parts store and look @ inexpensive Made in China valve springs (s/b under 1$ each with tax).

This said, it would probably be about the same $ to just double up on the stock footers.

Live Vibe brass decoupler sets are better than any springs out there. 

Springs lose their tension. 

The rocker springs I pulled from a 1990 Buick 3.5L V8 were plenty springy. Your springs will be fine.
