Yeap same price for custom rates and pillow balls all round.
There is quite a lot of adjustment in the dampening to give you what you like best. They will also revalve the coilovers according to your spring rates (over a certain range from default, can't remember exactly) so no issues there.

Didnt know you can get BCs in custom spring rates?
most 'off the shelf' seem fairly stiff... not sure if it's the damping/settings or the rate
