Default Perfect Shocks

What's the right way to build shocks? Does it have to fully rebound or no rebounds at all. And what is the purpose of the foam that sits on top of the membrane found on Tamiya, HPI shocks...does it make a big difference? I have been rebuilding my shocks ever since so that it will fully rebound ever and I want to know if I am doing it right.

Has anyone tried the Losi shock matching tool? is it good to have?

Any comments are appreciated. Thanks.

There is no need for the shock to rebound fully, although about half-way rebound is typical.

The aim is for the damper to be air-free and to behave as linearly as possible. So, you shouldn't notice any stiffeneing of the shock close to full compression, and there shouldn't be any squeaks.

The foam wedges are there to keep the diaphragm in shape and also to give a firmer rebound if you want it. Personally I feel they make the rebound too strong and I've removed them from my Yokomo. 1/10th shocks aren't dual-rate, so using wedges to tune rebound seems a bit pointless to me, as it is bound to affect the bump/bound too.

The way I have always built shocks was to get the air out and bleed/fill the shocks until you get about 1/8-1/4 inch rebound and that they are equal. Making sure they rebound equally is very important. I have the Losi shock matching tool and it does what it says. It's great for measuring shock length because if you use a pair of calipers then you have to worry about flashing on your shock ends.
