May be a good idea to rebuild them. Take them apart and clean with motor spray, wipe them off and blow with air compressor. Put some grease into the outdrive itself and on the barrel piece that the set screw and pin go through. Try using the Hudy graphite grease, it works wonders. I do this routine about every 3 race weekends. Sometimes more. I usually run in the super stock class (13.5 blinky) and never have chatter issues except when the cvd's need cleaned and greased. Hope this helps!!
I have a nice set of Double Cardan's arrive through the post today so I will replace them and pop the CVD's in my project 4cell speed run 415 chassis

I don't want to argue with you, im just stating the facts as i know them, about how the physics behind roll center work. You are free to do what works for you!
If you would like more information on how roll center works, here is a great read.

Both Elvo and the Hudy/Xray setup guide will tell you the same thing I have. And yes, I have tried it 100 ways back and forth in both offroad and onroad and the physics stated in both places can be easily seen in practical application.

Have anyone counted the weight of tamiya gear diff (with oil) before and after the race ?

Look at it this way, the shorter the link, the more effect on both the roll center and camber gain. For longer link, the effect of roll center is more than the camber gain.
The only way to find out is, indeed, to try out on the track.

i guess some people think of more steering when it turns fast on entry while some think of it when in the middle of the turn... based on experience (probably relatively shorter than most here) more shims less aggressive turn-in but more grip on that side in the middle of the corner and the opposite for less shims. for me camber link shims affect the balance of the car in the middle of the corner which can also translate to more aggressive turn-in (must balance the shim height between front and rear at most 1mm-1.5 difference). but i feel that the change is more apparent in the middle than entry and then magnified on sweepers.

I tried this too, and upping the shims made the car feel a little lazy, but had more roll capacity = more grip.

On the tamiya oring, the ring itself spins in the housing. but the kyosho makes it so the outdrive spins inside the ring.
