As far as the options goes (UI), keep in mind that not a single car in the *original content* has this enabled, so that's why Reiza took this option off. You find the options (clutch types, FFB types, etc) only when using mods that originally were made for rF1 and then ported.
Spotter: try to run the SpotterConfig.exe (found inside the SpotterAddon folder) and set the options as you like.
Hope it helps.
Cheers
