I understand your frustration with the shivers.

On my '06 EC300 I started with 0.44 springs and found what you are experiencing. Early on, I was about 215 lb. I am now down to 205 lb. Most of my riding is on rocky, root infested trails.

Step wise I increased the spring rate and oil viscosity (easy stuff first).

I now run 0.47 springs and 20W oil. I have not changed the valving. I did crank in the rebound & compression damping a bit.

They now feel very good over the rock gardens and the whoops. Heavier springs and oil keep it from diving too much. It still has a plush feel.
