You adjust the tightness of the geardiff with those different viscosity diff oils...

Schumacher is by far the best diff grease. It is thick enough to run the diff loose and keeps everything good and smooth.

Have you guys ever tried RCSpeedworks diff grease? Very very sticky and heat-resistant. I have been using this the last weeks now and it is far better than Schumacher grease. I've tried everything from Associated, Schumacher, Trinity, Serpent and so on, but the RCSpeedworks grease works the very best for modified (or anything else). No more slipping diffs for me and almost maintenance free racing.
Also tested and occasionally used by Jilles. You just need a small amount and you're ready to go.

Nothing else for me.

Associated sucks they are too thin for MOD usually couple of heat race you feel the roughness on your diff.. Schumacher is pretty good the grease is nice and thick.

Associated make two diff greases (diff balls not thrust)... One has red writing on it and the other has black writing. The black writing version (I believe they call it stealth diff grease) is thicker and works better for modified. The other stuff will give a slightly better diff but won't stay in for long under mod loads. It is better for slower classes like 25.5-17.5.

As a point though for best performance in mod, frequent diff rebuilds are quite norm.
