I'm preparing to refresh the suspension on my '84 coupe. It came with Bilsteins (green) from the factory. They now have 165k miles on them, and I figure I'll want to refresh them when I do the bushings and such.
I'm not a hard driver. My car will probably never see any track time while I own it, I use it as a Grand Touring car. I definitely won't be upgrading my TBs, nor will I be using anything other than normal rubber bushings (Elephant OE-hardness). I don't find the ride on my car to be bad now.
So given that I'm looking at keeping the rest of the suspension totally stock, is there really going to much difference between simply replacing my Bilsteins with new HDs vs. having Elephant re-valve them digressively?

Here's a general view of the difference between stock hd linear valving and digressive valving which is most common in modern racing shocks
The linear will be fine for street use but what happens is as shock speeds build shock control forces also build, you get less control at low speeds and too much at high speeds, this is fine for street use but on track on smooth pavement and in most corners the shock speeds are relatively low and you want more control but you also want the shock to handle turtles etc at speed w/o upsetting the car so the tapering of control at high speeds is a big plus, this is where the digressive setup shines
