You can disable the traction control and DSC by pushing and holding the DSC button until the DSC symbol and the yellow "Brake" light are illuminated. Obviously if the car is powered off it defaults to the enabled state.
You can permanently disable it by unplugging the yaw sensor below the driver's seat. You'll need to remove the seat and the door sill plate to do this, but it isn't hard.
Not recommended for a car that is street driven. The DSC is there to help save your butt if you get in over your head.
