Racing Controllers is a broad category that encompasses the vast majority of third and first party controllers that has everything to do with racing games.
The [OverSteer Project](https://github.com/berarma/oversteer) is trying to manage support multiple Steering Wheels on Linux. It is still in the early stages of development.
Oversteer manages steering wheels on Linux using the features provided by the loaded modules. It doesn't provide hardware support, you'll still need a driver module that enables the hardware on Linux.
Most wheels will work but won't have FFB without specific drivers that support that feature.
