Hit curb, car is now super unstable.

[dued]

I recently hit a curb with my front left wheel. I hydroplaned in the rain on an off ramp, but I was able to counter-steer and brake to get my car almost parallel with the curb before hitting. I messed up the lip of the wheel pretty bad, and replaced the wheel with a new one. I checked the arms when I installed the new wheel and nothing "appeared" to be bent. The camber and alignment still look good. I did notice a slight vibration in the front end around 60-65mph. The worst effects though is that when I brake heavily, the whole rear of the car feels light and like its going to whip around. The front end seams super twitchy now also. I'm wondering, what is the most likely component to have been bent? The tension rod, FLCA, or is there anything else?
