INFORMATION ABOUT THE PEUGEOT 106 XR REAR TORSION ADJUSTMENT

Should I lower the torsion of my Peugeot 106 xr model car, it seems to me that the back is too high, but I am unstable Are those who play with the torsion settings satisfied?

I am uploading the pictures of the vehicle immediately tomorrow we will solve the equation with the unknown, I hope :)
