Curitiba and the Giant Bouncy Castle. Set Up Help.

Hi all..... wonder if anyone can help me.
I have watched some videos on YouTube etc of other people driving the 2014 Stock Cars and one thing i have noticed is their cars always seem way more planted than mine - especially at tracks like the aforementioned Curitiba!
When i race on this track my car is bouncing and pitching itself all over the shop. How do i create a more stable, less 'bouncy' set up?
I have tried stiff and soft dampers, raising the ride height.

All suggestions greatly appreciated :D
