Perhaps splitting hairs but if they don't fit, they don't fit. Even if the EDC shocks are a different size than non EDC shocks the springs for the EDC system are not "special". What I meant is that a spring has a size, rate and travel and that is about it, you can't "tune" a spring in some mystical/magical way to match EDC.
