Simon, this is not about negativity, it is about objectivity. It is very easy to be seduced into thinking an upgrade is better, if you don't have data to back it up. This does not just apply to suspension upgrades. When I suggested you post data/results, it was not about posting your damper curves. They are of course your intellectual property and it's understandable that you don't want to publish this. What I meant was results from your car - I assume you confirmed the ride was better objectively, by doing PSDs of accelerometers fitted to the car? By showing the heave and pitch response from your logged data, a clear improvement in ride should be seen. This makes it completely obvious that the damper change has made a difference. The exact analogy with engines would be to post a dyno power curve, showing the results of an upgrade - you would not expect an engine builder to publish his secrets either - but you could imagine they want to show that objectively there was an improvement. I speak from experience of running and analysing performance data of racing cars over 23 years. I don't claim to have all the answers. It's true, sometimes you can be surprised and find a benefit where there previously was none. But generally I would want to see hard data to back it up. When people do these upgrades, my impression is that they very rarely do the due diligence of dynoing the old dampers, changing to the new dampers whilst keeping the same springs, doing the corner weights and setup and then going back to baseline at the end for a proper test. In my professional life, I've heard drivers swear blind some damper tweak was a big improvement, only for this to be negated by going back to baseline.
