Need little help on dampers setup

[OxO.K]

Hello,
I'm trying to make a correct setup for the Porsche 963 lmdh (SDD) for le mans track. (i use a pad controler...)
Base setup used is originally for Spa track.
I would like to setup the dampers in order that the car stop bouncing on the corner vibrators.
For example in the "tertre rouge" corner with the 919 hybrid there is no problem to put the weels on litle vibrators but with the 963 it's impossible, the car bounce, loose grip and crash.

Current setup in the post.

If someone could help? Thanks.

Here are my setup you can look atthe dampers on these. The LMDH porpois like F1 because of the diffuser. Good Luck
