The only Bilsteins made for our car that I know of are the HD series shocks. They are made to be used with stock spring rates, but can be revalved for any spring rate and shock dyno'd with a plot sent to me for $65 a piece. I would be using them with Ground control 8/6kg spring sleeves.
The car's main purpose is spirited mountain driving and normal street driving, but I want it to be fully capable for road racing days.

I'm hoping to get either setup at a much cheaper price than retail, so those prices don't really factor for my decision.
