Putting a foam on the diaphragm will cause an higher pressure on the oil when the damper is compressed, so the piston rod comes out (because of the piston rod volume has compressed the diaphragm and the foam), so this is for me a push out force on the piston rod. (as gas force on a real damper)
Building a shock with "rebound" is to close it with e.g. fully compressed length during closing process. As result the shock sucks the piston rod in, which is a rebound force, isn´t it?

So leaving out the foam will cause little more "rebound" as with a foam, as long as closing the shock in the same condition.

In my last TEC race I saw the M03 winner building his shocks with fully pressed in piston rod and without foam, as I would see it "full rebound"...

That´s just how I understand it, but do you guys here see it the other way round? To compare setups, it´s important to speak the same language...

So let´s discuss, I´ve still a lot to learn about setups!
