However, i am not sure whether i should adjust my rear and front downstop
The downstop helps adjust traction when your car is experiencing weight transfer.
For example, when you approach a turn and slow down weight is transferred to the front. This results in a lifting effect of the rear. If you don't have much "droop" /downstop, your rear end will un-weight itself such that the rear tires will lose traction if not lift off the surface entirely.
This could be what is happening to you when you are losing traction in the rear as you try to turn. Since you soften the front springs, this weight transfer from rear to front is increased even more which means you need more droop to maintain contact of the rear tires to the track to have rear traction when transitioning into turns.
Keep in mind:
High downstop number = less droop
Low downstop number = more droop
