Noticeable how? My lap times were virtually identical with both piston types. The car behaved much the same through all terrain. Granted, I'm not a pro, but am an extremely technically savvy person and am fairly keen to seeing and feeling minute differences between products and with the tapered pistons my car felt the same. Even the drop test was no different.

What I have in mind would change how the piston interacts within the shock body which would affect dampening and rebound differently to how current tech does. Tapered Pistons do indeed affect dampening and rebound but I don't think any human being can gauge the difference because of how minuscule that difference is.

In fact, if you were to do an ultra slow motion capture of a shock with each type piston in there the rebound would look pretty identical and equally so, dropping an equal amount of weight onto each shock would produce an identical resistance figure.
