These files are vastly better than whats included in the game, I would of given it 5 stars but what's with the engine vibration? It's constant and actually ruins the good work you did at conveying what the tyres/suspension geometry is doing.
I'm using the "Smoother" file, but to anyone reading this, if you're annoyed with this constant fake vibration (it hides road surface texture too) go into the file and change this
# Engine ---------------------------------------------
(engine_vibration 20)
(engine_vibration_while_driving 20)
to this
# Engine ---------------------------------------------
(engine_vibration 0.01)
(engine_vibration_while_driving 0.01)
Now it feels like a blend of Assetto Corsa and rFactor 2 FFB, but still just not quite eclipsing both.
