Khonis or Bilsteins for Autocrossing?

I currently have new Bilsteins in my '74 Carrera 2.7 Euro. Real hard ride with Bilsteins (as expected). Anyone have opinions for best type of shocks for light amounts of autocrossing (I use this car as a daily driver) or club racing?

We have Koni adjustable Sports on our 1987 Turbo. They have a pretty good range of adjustment for street/autocrossing although they are stiffer than the OEM Bilsteins that came on it. I set them soft for street and stiffen up the rear for autocrossing as we have some understeer.
