...the track is rutty:
Try changing the center to a lighter setting first (3,000-5,000wt);
if the car is changing directions out of a bumpy corner, try making
the front lighter (3,000-4000wt).
...the track is loose
and smooth:
The best way I've found to increase traction with the diffs is to
increase the oil weight in the rear diff slightly -3,000-5,000wt.
...if the track is loose
and rutty:
A "square" diff setup here helps -5,000wt front, 5,000wt
center and 3,000-5,000wt rear.
...the track is blue
groove:
Most of the time I run between 5,000-7,000wt in the front, and
7,000-10,000wt center.
...the track is blue
groove and rutty:
I would normally just go lighter in the center, but not too light
(5,000wt)
... I want more steering
entering the turn:
Lighter front oil (3,000wt) and rear (1,000wt)
...I want more steering
exiting:
Thicker front oil -5,000-10,000wt
...I want more
acceleration out of a turn:
Thicker center oil - 7,000-10,000
...I want it to go
better through a rough section:
Use thinner oil for the center (3,000-4000wt) and thinner oil for
the front as well (3,000wt).
...it pulls around too
much through ruts:
Usually this happens because the oil in the front and center
differentials is too thick; reduce weights.
