He is asking about rubber banding not how to win it.
Never done it myself but do a search on it and you'll find the thread I'm sure.
Basically you put an elastic around the left analog stick so it is pointed up and to the right slightly (do some test laps with it to ensure you've got it right) and then using the default right analog stick as up is the gas then you tie a rubberband around it so it's pointing...well up. Then press start and theoretically a x2010 is still suppose to do pretty well at this. Apparently there are some issues with the car actually turning backwards but you'll have to find the thread.
