In the CSM.ini file in the Settings folder of your mod, activate the HighLodOnly=0 option
to
HighLodOnly=1
Inside the Data folder, you will find the Tweaker folder and inside the gp4tweak_data folder. There you must edit the INI files you want for helmets, steering wheels, arms, wheels, etc. (they all have very intuitive names)
You can download this guide that will help you very quickly understand CSM
