some news:
I found a way how to edit suspension geometry(it means to create suspension travel like double wishbone).
When i removed wheel.setArm function from suspension java, the wheel travel directory changed like camber was locked(like double wishbone).
Still i don't know how exactly it works, but i'm figuring out.
The function has lots of variables:
setArm( float len, float px, float py, float pz, float nx, float ny, float nz );
I just can speculate that first value is some kind of length, the others are 3 dimensional coordinates for two points(upper arm, lower arm coordinates?).
Spoiler: 
Any ideas?
Edit:
Apparently same result can be achieved by editing wheel.setHub function. I'm confused 😃
Ant it have even more variables
setHub( float len, float p1x, float p1y, float p1z, float p2x, float p2y, float p2z, float pcx, float pcy, float pcz );
