Do you know how to make stiffer suspension?

Hi, is there any way to make my suspension stiffer?
I mean that I like making stanced cars and in my opinion in-game suspension isn't stiff enough. When you stance your car the wheel is going thru fender texture and I don't like it (if you are making stanced cars you probably know what I mean).

I was looking for someone that had same situation but I didn't find anything. I'm mainly looking for Ibishu 200BX suspension but probably it will be the same way in other cars.

Maybe you know what parameters and which files you must change to make what I want to do.

There are some pictures of my setups:

 

Just crank the rate and damping to the max in the tuning menu ?

 

It's not stiff enough. When you drive wheels are going thru fenders even if you max suspension settings in Tuning Menu and that's why I'm asking for someone who could help me in changing something in the files of the cars. But thanks for try to help

 

You probably could increase it more by modifying the max value possible but you probably couldn't get very far because it starts shaking and imploding on itself and it probably won't be enough to fix the problem. I would tell you to tuck the wheels back in or increase ride height but that's against the point lol

 

there used to be good stance mods...
