This procedure is called a "zero-balance". Shouldn't ever be necessary. It only happens with cheap, aftermarket wheels. This is why you should NEVER buy a replica. They all will shake, rattle, and roll at some point. These are expensive cars that are deserving of authentic wheels. Don't be cheap. You'll hate life later on.
Note also that not all MB dealerships have this balancing capability.
