Ohlins R&T with swift 8kg front and 9kg rear. I also have the stock 11/12kg springs that I will not be using.
The high speed damping is fixed by the shim stack. This is most likely what redwood adjusts to make it engage sooner.
Low speed is controlled by a needle valve and effects both compression and rebound. On the rear shock at about 25 clicks from stiff the low speed compression matches the stock damper. You can go softer than stock and still have the blow off for bigger hits.
Still working on this as I'm doing it in phases and documenting everything. I have a background in autoX and work on MTB suspensions in my free time.
This is a street setup. Comfort and control are the goals. keeping it off the bump stops maximizes both.
