Advices needed on BX world

[fifi]

I have trouble with my set up on the BX world.
I am new yokomo user. Use to drive X5 and XX4.

with standard kit setup.

The back of the car slide when I accelerate after a turn.
The car goes 180°. I run losi stud all around.
Slipper is loose and diff also.
I thaught I had too much traction in front but I don t
have enough steering.so I put used tires in front and it the same.

Thanks,
