Forza Motorsport 7 is an arcade racer first and foremost, designed primarily to be played with a controller, but it actually plays well with a wheel. In fact, the default force feedback settings for the Logitech G29 or G920 aren't that bad, which is almost never the case.
Usually default settings make the wheel feel excessively heavy and hard to turn. That is not the case here. My main complaint was that the force feedback felt muted, like it was disconnected from the road, and the rotation angle is way too large.
With some tweaking, I was able to find settings that make the force feedback feel sharper and more connected to the road. The steering angles can be set in the car tuning menu on a per-car basis. It would have been nice if these were already set to the real-world value, but it's not too hard to do this manually.
There are so many cars of wildly different types in this game that it is difficult to find the best settings that work for every situation. I focused on the sports cars, but these settings seem to work well across all the different types. Remember that you can adjust the force feedback strength individually for every car in the game.
G HUB Settings
You can't create a profile in G HUB for Forza Motorsport 7 since it is a Windows App. Instead, it will use the settings from the Desktop profile. What I recommend is to set the Desktop profile to 900° rotation and change the steering angle in-game on a per-car basis.
Make sure that the Desktop profile uses these settings:

My goal with these settings is to make the wheel more responsive without feeling too light.
In Options > Controller > Advanced:
|Steering Axis Deadzone Inside||0|
|Steering Axis Deadzone Outside||100|
|Force Feedback Scale||100|
|Aligning Torque Scale||120|
|Mechanical Trail Scale||80|
|Pneumatic Trail Scale||160|
|Road Feel Scale||100|
|Wheel Damper Scale||0|
|Center Spring Scale||0|
|Dynamic Damper Behavior||100|
|Invert Force Feedback||Off|
|Use Gamepad Steering Filters||Off|
Steering Axis Deadzone Inside should be set to 0 or there will be an area around the center of the wheel that will have no input recognized.
Steering Axis Deadzone Outside should be set to 100 to use the full range of the wheel's rotation.
Vibration Scale vibrates the wheel when you lose traction. I find this quite distracting, so I turn it off completely.
Force Feedback Scale is the overall strength of forces. You can change this on a per-car setting using the Steering Wheel Tuning option in the car Setup.
Aligning Torque Scale is the main force feedback you feel. Setting this too high will make the wheel jerk around too much.
Mechanical Trail Scale is lowered to make the force feedback a little sharper and more responsive.
Pneumatic Trail Scale is raised to add some weight to the wheel.
Road Feel Scale controls the vibrations you feel from bumps in the road surface.
Load Sensitivity gives more information about the car's tires. It makes the force feedback feel more responsive.
Wheel Damper Scale makes the wheel feel heavier without adding any information. There isn't much reason to use this with these wheels.
Center Spring Scale pulls the wheel back to the center position. Like the Wheel Damper, there isn't much use for this on these wheels.
In Setup > Tuning & Upgrades > Steering Wheel Tuning:
It's important to set a proper steering angle for the car you are driving. By default, Forza will use the full 900° rotation of your wheel for every car you drive, which is way too high for most of them.
Thankfully, you can set the wheel rotation angle for each car individually. I typically use 720° for road cars, 540° for rally-style cars and 360° for F1-style cars, but if there are some cars you really like, you can always find the real-world steering angle and set it perfectly.
There is quite a lot of confusion about whether to set the Steering Assist to Normal or Simulation. When you are using a gamepad, the Normal Assist does some magic to adjust the input as well as the physics to make steering easier. When you are using a wheel, only the physics changes apply, nothing happens to your actual inputs. In Simulation mode, both the input and the physics changes are removed entirely for both gamepad and wheel.
Some people say that when you are using a wheel, the Simulation setting improperly affects something about the physics. The posts I found discussing this were several years old and written before a major patch that completely revamped the force feedback system, so it's entirely possible the information is outdated. I have been using the Simulation setting without issue, so I'm assuming this was fixed.
Being used to the physics in Assetto Corsa, I actually found Forza 7 fairly difficult to play. The physics are different enough that I had to relearn how to drive. I was hoping that some of that could be fixed by changing the force feedback settings, but, in the end, it's just an inherent part of the game. Once I got used to it, though, I starting having a lot more fun. There are a lot of great tracks and huge number of cars to drive, leading to some very interesting race moments.
Let me know if you have any questions or comments.
