It should have installed all the base content. If you unsubscribed from all items in the workshop you won't have them 'installed', but they're still sitting in that 11GB ready should you want to install them (by subscribing; no download required because you already have the files). If that hasn't worked then hopefully someone can help; mine went without issues. The ironic part about your constant "10 year old engine/game/graphics" stuff (yeah, it's not the prettiest, but it's not THAT dated) is that the wheel you keep talking up, and which you said was released in 2011, is basically the same as the G25 which was released much much earlier. The main difference, apart from more wheel buttons, is the angled gearing which makes it feel smoother but produces that horrible noise when you run over kerbs and grass. And adjusting the FFB settings WILL make a huge difference to what you can feel with the car, because it sounds like you're running the force way too high. Again, clipping, etc. If you want to make the sim feel more like a sim you need to learn about this stuff.
