Like I said in one of my replies, the only time I've seen things really broken in drifting is when they were already weak (original on an old car) or someone hit something. If you've broken something durng drifting, your car probably isn't properly set up for ANY motorsport.
I don't understand why you people build your cars if you're not going to do anything with them... I already said that. It makes no sense to me, but to each their own.
