my car has silk road coils with an 8/6 spring rate setup and very agressive valving. jason's car has the same spring rate but a much less agressive valving.

tein makes 2 sets of coils you should look into that will let you adjust the height but not compromise your stock-like ride quality too much.

the Tein Basic dampers are a 6/6 spring rate combo and I would imagine would not be too agressively valved, as they are designed for a street only vehicle. the Tein Super Street coils have the same spring rate combo, but would most likely be valved more for performance than comfort. I'd say check out the tein basics. the only "bad part" is that neither setup includes camber plates. but since its a comfort oriented dd that has shocks/springs on it now, I didn't think that would bug you too much.

Edit: one last thing. a friend of mine from school had a used set of tein super streets on his car. I drove it and rode in it and was suprised b/c it was a decently handling car, but the comfort aspect was definitely the focus of those coils.
