Well there is a trick I found out by being OVERLY frustrated with the same problem on my G25.
Once you are in your car, go to controls, and click the Accelerate and when it sais push the axis or wahtever, push very very slowly, once you hit the stop, let go quickly, do the same for the brake pedal. This fixed it up completely, but the stupid wheel skid still sounds but its not actually skiiding, and with the sensitivity lowered on the wingman controls, it will be better.
BTW, I also drive with 900 degree xD
Maug: Do you use the G25? It does have a problem with the little feel of FFB while centered, if you search around on google, theres a fix for that.
