GTR2 is hard-wired for a force feedback wheel set to 240 degrees of wheel rotation. This was likely done to accommodate old wheels that had very low wheel rotations. Newer wheels with 900+ degrees rotation still work but you can feel that you have to turn your wheel much more than you should to turn at the angle you expect (you probably compensate for this by raising the Steer Lock in-in-game.
This actually matters for a number of areas of the game.
Firstly, the in-game cockpit wheel animation is limited to 240 degrees and it won't rotate at the same rate unless your ffb wheel is set to 240.
Steer Lock also begins to make much more sense in the game. The default Steer Locks now feel like they're steering the car at the proper angle for your physical wheel's angle.
Force Feedback is also affected because ffb calculations in-game assume 240 degrees of rotation and output a signal best suited to a 240degree wheel. When you use a 540/900/1080 wheel those signals are no longer best suited and the feel will be different. This isn't so bad, normally, usually it just means things feel less sharp the more degrees you have on your ffb wheel. Up until recently, I had been using and tuning ffb to 540degrees. This said, my SHO Competition FFB mod feels decent enough without any changes at 240degrees.
I'm guessing here, but it seems plausible that general car handling was presumably also tuned to 240degrees during development meaning cars likely feel closest to what the developer intended on a wheel set to 240 degrees. And being closer to what they intended is also presumably closer to reality.
There's actually not much downside to setting your ffb wheel to 240degrees for GTR2. It feels just about as enjoyable to me.
One downside is less fine control in rotation through your ffb wheel. A 900degree wheel, like a G27, would have 3x+ degrees for fine control, and vice versa, 240degree wheels have 3x less degrees. In theory, more degrees gives you more control by having less dramatic steering effect per input. In practice, though, you may not notice a difference. Give it a try, it's still just as fun.
Another downside is lock-to-lock bump stops come up quickly. You can't rotate much past 90 degrees before you're hitting them. It feels strange at the beginning but it also has taught me to appreciate my cornering speed vs steering angle more and, instead of scrubbing so much through a corner (having steered past 240 degrees), I'm attempting to slow down but keep maximum grip and speed through the corner.
Give it a try. You might find you enjoy it. You can probably set a game profile to 240 degrees specifically for GTR2 in your ffb wheel's software. That's what I do.
Edit 7/15/22: Two years later and I'm still using 240degrees for the old SimBin games. I just got used to it and I love that my on-screen wheel matches my physical wheel.
