I'm sorry but I'm not fully convinced with the motion you are getting, maybe someone else can correct me why does it look like that. I see the percentages from forces, but it doesn't look right, like there is not much g-force simulated in places where it should most.
When you hit a brake the simulator is moving you flat back instead of moving you a bit forward and leaning you down to simulate effect of g-force while braking, which would be pushing you towards your wheel.
When you accelerate, it moves you flat forward and there is also not much movement, but this is very fast car you're driving - it should move you back and lean you back to simulate acceleration force, pushing you back in the seat. It looks like braking and acceleration profile settings are reversed.
Also, the simulator is strafing you left/right when you are steering and drifting in corners, where it should rotate your back side to left/right to simulate traction loss.
Please don't get my comments wrong, this is very nice simulator, great work, but I think there is much more potential to enjoy it more with better setup / profile..
