Physics Car tilts over when turning = no proper drifts or normal curves

Hi there,

im "new" to car modding in AC. And now im having a issue with the suspension... everytime I'm driving left or right doesnt matter im almost rolling over, I adjusted the graphics offset to

[BASIC]
GRAPHICS_OFFSET=0,-0.1,0.20
GRAPHICS_PITCH_ROTATION=0
TOTALMASS=1665
INERTIA=2.030,1.210,4.210

Now the tilt doesnt happen anymore... but is it right what i have done? or is there another way to solve this?
heres my suspension.ini:

Reminder: This is only for testing! no actual realistic data, im trying to understand which setting causes this...
ah and also i cant drift or make a proper burnout some wheel is always off ground idk why.
Its just really weird to drive... its so "stiff" like no realistic movement. And when i brake hard the wheels go sometimes through the hood...

Anyone any advice? Help would be really appreciated :)

Do you have Content Manager? If you open the car in Custom Showroom you can better visualize the cars suspension, which may help to find what's wrong with it

Yes im using CM, but in Custom Showroom i cant see whats wrong with it...
there are these two things (Forgot name xD) Blue and red and i think something with them went wrong...
test2.PNG
And i dont understand what this blue "platform is... (Yes i know my glass isnt configured right)
 
Nevermind, i found the issue myself!
It was because
[BASIC]
GRAPHICS_OFFSET=0,-0.1,0.20
GRAPHICS_PITCH_ROTATION=0
TOTALMASS=1665
INERTIA=2.030,1.210,4.210

Graphics offset the Z-Axis was actually too high so it put the "center of gravity as seen in picture in the middle of the car... fix was to change -0.1 in= 0.1, functions now properly :)
