I'm interested in the Smart Madness lowering springs. I have a 2015 electric drive, and have read the one review from an electric drive owner who was very satisfied.

I have some questions. Compared to the other lowering springs you offer, how does the stiffness compare to those?

How much stiffer are these springs than stock? Do you have the actual spring rates for your springs and also for the OEM springs for an electric drive model?

Thank you.
