We haven't ran both, however I have spent a good amount of time in the past month talking with Bilstein Techies and a Bilstein Representative to have somewhat of an idea about the uses for the different valving types.

I'll preface this by saying that there is probably someone, or possibly even several people on this forum that know much more about the technical side of the different valving types than I do. Hopefully they will post as well.

Anyhow, from what I was told by the Bilstein folks that I have spoken with, Linear valvings are often well implemented on the LF, RF, and RR of cars on smooth/slick tracks where you want the car "down into" the track surface. They recomended sticking with a digressive valve on the LR. I do not recall the exact reasoning, but it was something to do with the LR needing a quicker responding shock than the other three corners, even on the smooth/slick stuff.

From what I gather, on rougher, heavier tracks you want to use the digressives all the way around. However, all of the people I have spoken with have recomended ordering the digressives (or having our current ones redone) with lower gas pressures as they say the factory setting is too high pressure.

...kind of makes me wonder why they just don't build them at lower pressure...

Anyhow, hopefully someone much more informed than myself can chime in and give you some good technical information on both valving types. I would like to see what others have to say as well.

On a side note, we have ordered a few linear valve models to try out as we spend 90% of our time on dry slick tracks when the features roll around.

Hope this at least starts you in the right direction

On another forum, a shock man in MS. talked about what you are asking about. His web site is and he could tell you what you need to know.
