The 400ex and the z 400 are very close i think that the driver do the difference because i race my friend with is kfx and i beat him close he take my ex and i take is kfx and i win close
As long as the prices are the same, buy a z400. I own both and I would buy the z400 over the 400ex, as long as I wasn't paying more than a $1000 premium. Year for year, condition for condition.
Z's are faster. Your buddies z is not set up properly.
