Ways to reduce rebound? or car Jumping?

[ghostuss]

my suspension is too bouncy even on the softest. I have tried some other car with coilovers at the same sping rates, and they are not even close to as bouncy as mine. My friend who drives behind me always claims that I am "all over the road". and it does affect my handling cause when I go airborn in a turn, I feel like my steering just lost response so who knows what might happen one day in one of those mountains.
