So that gives us a spring rate of 1.9k front and 2.3k rear

Tanabe DF210: 3.0k front, 2.2k rear

Tanabe NF210: 2.5k front, 2.2k rear

I don't understand the post. Are these stiffer than stock springs and stiffer than the DF210's?

Can you just swap these directly with the stock springs without changing the shocks or anything else?

hi Tony
These are stiffer than stock in the front (but softer than DF210) and the rear is stiffer than DF210 (just)
and yes you can fit these without changing your stock shocks , if that is what you want to do.
Hope this helps
