*From what I understand*, the actual DFV only works on ultra high speed movements. You shouldn't feel it working during normal driving.
Its just a tertiary flow path. Shims handle low/medium speed. Piston blowoff handles high speed. DFV handles ultra high speed simultaneously.
The DFV isn't active all the time. Otherwise, you'd have no damping. Its an ultra high speed blowoff to keep the tire on the road over track curbing or landing a jump, or very sharp/high bumps that the piston cannot handle by itself.
The DFV bleeds the pressure that the piston cannot handle. The piston and shims are bleeding/controlling flow at the same time. When ultra high speed movement slows down enough, the DFV closes.
It would take an abnormally large impact to activate the DFV. Its purpose is to handle *abnormally* high speeds.
The DFV should not normally work during driving. I don't even know if it shows up on most dyno graph speeds. Evidence of this is that setting the clicker overly stiff will result in a non-compliant ride and the car will skip over bumps if you over do it. The DFV has nothing to do with that.
LMK if I'm understanding the concept incorrectly.

My guess is it was designed to help with the impacts on any rough freeway. I would say it does more off the track then on.

Probably the 2nd best solution with these shocks, is to bump the preload to 10mm or more and sacrifice some droop travel. Getting some more impact comp travel would take the bumpstop out of play on more obstacles.
The best solution is probably to go to a 10k spring and back the reload down to 6-8mm or so. In my experience when it comes to overuse of the bumpstop, going with stiffer springs can actually make the car ride better.

Redesigning the lower mount to accept more threading allows you to add preload without adding height. I met up with an Öhlins distributor/acquaintance at a track day...and he had mentioned how they set up their Öhlins by modifying the mounts. He said it was easy and to ring him up when I wanted to adjust them.
We'll see. I will disagree that my car is "riding on bumpstops" at static height due to Öhlins' factory settings. Its not. But it certainly over-uses them during street use and its really annoying.
