alright guys. i tried everything you guys said and i aprreciate all your guys input.

my current set up is:
ball diff in the front
stock diff mod in the rear
yokomo zero one R tires
carbon top plate
metal motor mount
aluminum steering rods
19X2 motor

and it still has major understeer or if i get it to drift im trying hard to keep it in the drift or when i transition it just spins out?

any input would be great, like if i should get some more hop ups to help my drifting?

thanks
