Nice setup, OP! I was torn between the Fanatec rig and the Humanracing chassis at one point, but since I want to add motion, the HR was the best bet. I've never used mine for anything but iRacing, until last year I went ahead with Assetto Corsa (great Sim, more fun imo, but less serious and competitive than iRacing). Recently joined the "Race Room Italia" club, too and it's fantastic so far.
Here's my current setup, waiting for next wave of the Rift to make the jump to VR, but will still run the screens for longer races I think, especially 2 hours endurance races, I think it'll be a lot more comfortable..
Human Racing GT full motion rig chassis (no motion, yet..a cool $10k more) full fiberglass shell with aluminum core to translate vibes and forces better throughout.
Sparco R888 Reclining Race Seat
Fanatec Clubsport V2.5 wheel base w/ BMW GT2 replica rim, and Formula Rim.
Fanatec Clubsport V2 Pedals
Fanatec Clubsport SQ Shifter, does Sequential and MT mode(s)
DSD Button boxes, custom made to fit directly on the wheel base.
2x Buttkicker Gamer 2 transducers
Sim Vibe mounting kit and software which works with iRacing, Assetto Corsa, rFactor2 and the ladder of sim software's.
