That's not the critical dimension... it's the suspension travel.
I've noticed the same effect, but am not surprised by it due to the light weight of the car and the small wheel diameter. FWIW, the feeling *I* get is not that the suspension is bottoming out; rather, that the axle is banging against the LOWER limit as the springs recoil.
I suspect the Versa's weight distribution with just the driver onboard is heavily biased towards the front, and the light back end gets flung around more easily.
Keep in mind that the suspension is probably designed for a *maximum* weight situation. Put three friends in your Versa, and it might take those speed bumps easier.
Then again, you might end up with dents on the inside of the roof. :-)
