fast and the furious kit compatible with z-cars?

Last week, I went out to look for zipzap cars at local radioshacks but I had no luck finding the thing. All I got was the fast and the furious kit hoping that I'd find a starter kit soon. The saleslady at radioshack told me that zipzap shipments won't come in 'til after new year's. Does anyone know if the fast and the furious kit is compatible with the z-cars that they sell at the Discovery Store? Thanks.
