esham,
What's the car doing wrong to make you ask that?
I ran MTX-3, Front Diff and Rear Negative Diff. Front 10,000wt diff oil and 7,000 Rear diff oil in Negative Diff. Front Toe out 1° and Rear Toe in 2°. Camber front 2° and Rear 3°. But the Rear Negative Diff is run so smooth tho.. compare than the front - manually feel. By this setup the car when into corner sharp with small radius but tend to spin out into corner like most of the weight to the front? " slip angle change"?.

So I change the front diff to lighter diff oil = 7,000wt the rest setting untouch. the " tend to spin" gone! but.... the turning radius become bigger I wonder is it really due to the weight of the diff. And suddenly spinning in my mind on this theory..." Because of the front diff oil is heavier and the tire has a good grip the turning angle will became small and slower and the light oil at the rear will turn big and faster. - This will make the car to spin out.." This is thorogh my logic thinking not math ..calc so excuse me..

So that why i ask here if that is true? Or maybe it due to my droop +5 ( probably is to musch for my MTX3 ) which make too much weight transfer to the front into cornering
