Jim,

I have never heard of any sort of device to make cars rock, though some do due to inexpert assembly via loose truck screws.
The big problem with rocking model cars is that physics doesn't scale. Prototype cars rock at a natural frequency of maybe once or twice a minute, guessing here, but it's a slow ponderous motion. Model car with loose truck screws jitter at a frequency of maybe once or twice a SECOND, which looks maniac, not ponderous at all. the effect is just nervous jitters.
