What's the easiest way to alter drive bias, I think I need more front/less rear?
 
Thinner center also.
Bigger wheels in front :D
 
Assuming you have three oil filled diffs...

Thanks guys. Sorry to be brief, I was trying to keep it short.
I'm asking about my Traxxas 4WD Rally car (Fiesta).
I'm put all the VXL stuff from my Rustler in it and it's really fast.
But, it seems the rear wheels are trying to do too much, not enough from the front.
Spins out too easily under power.
So now I'm thinking to thin out the rear diff oil. ???

Yeah, that will likely help.

Lots of variables here... are you running a center slipper? If so, Slippers are better suited for high grip conditions which very few people who run a VXL will ever see high grip on a prepped surface.

I would consider replacing the slipper with a center diff and start out with 10K fluid in the front, 7K fluid in the center and 3K fluid in the rear then your car will be a dream to drive ;)
