The secret is to have the car in the air and just 'tap' the spinners with a lead hammer.

Tap - turn wheel - tap next ear - turn - tap next ear - turn - etc. In less than one minute, it will be off. Having the wheel loose (not on the ground, car in neutral, etc.) ensures that you are applying a relatively light strike. The wheel turning puts some give in the process, making it less likely the spinner ears will break.

No hits, just taps.

Even doing this, sometimes the spinner ears will break during the process, especially if they are the old ones.
