What the hell, are you trying to do reverse donuts in a rear wheel drive car? haha.. Tokyo Drift Backwards!!
haha.. Anyway, I think that's probably normal.. Moving foward is how you are used to feel steering, with the front end guiding
the rest of the car to whatever direction. Going in reverse, it's almost like you have rear wheel steering, and the rear is trying to guide the rest of the car, making it feel a little less stable.. does that make sense?
