you will get a hard bumpy ride if the spring is a really tuff track spring.

These springs doesn't have that much higher spring rate. As I stated, the rear is only ~28% stiffer than OEM. Even with the front as twice as stiff, it wasn't that bumpy.

What I'm thinking is that the shocks compressed TOO much thus doesn't have room for damping movement, causing it to be really stiff. I'll try to shorten the shock body and see what'll happen.
