Check the wheels that where affected, or all of the wheels for buckling i.e. bent or a flat spot in the alloy where it hit the ground.
Check the springs as the impact might have broken off a rusty end of a spring etc etc.
Check for leaks around the shockers/dampers then do the stand over each front corner and push down on the car to see if the dampers feel ok (i think the car should drop with your force of pushing then return at a decent rate to normal)
Also get the wheel alignment checked and see if youve bent anything! (not sure if a pot hole could bend anything other than alloys, i suppose it depends on the severity of the hole).
