How to improve ride quality?

I would, under no circumstance, ever recommend cutting springs. IMO, I dont care who says its ok I simply do not approve of it. A good friend of mine cut springs on his S10 and he is happy, but I wont do it with mine. I simply do not see how you could expect safety, handling and ride quality all out of a cut spring. Prove me wrong, I'm sure many will, but I still wont do it.

BUT, on topic, start with some good dampeners. The stock dampeners were chosen to go with those springs. If the car rides bouncy, you deffinately need some dampeners as your current ones are unable to keep the springs in control. CC plates will allow proper alignment. MM plates do add some travel, but I doubt CC plates are going to fix your ride quality issue.
