Many owners attempted changes to the spring rates. Others changed their shocks and springs with some mixed results. Ride quality is a function of the balance between understeer and oversteer and often does not respond well to random changes.
Therefore,
I'd like to start a discussion on the subject and compile collective knowledge in one place.

So, what rates have you used, why and what are the results?
