Diff oil query - setup for tight turn in and big oversteer

[Jahay]

Thanks for that link, but i am asking for advice... I am asking what sorts of weight are more suited to a savage consindering buggys and truggys you lighter weights....

What about if i used

50k rear
50k centre - ofna spider diff, so should behave like 75k???
20k front

Should this give me really nice straight line traction as well as tight turn ins on grass.
I know my long fast turns will be killed a little by the 20k but i prefer fast, tight sliding turns...
