My wife is not used to driving such a low car and has a bad track record of hitting immoveable objects when negotiating tight spaces. She has been making an effort to pay attention, but today I backed out of a parking space that she parked in and felt the front of the car lower off the parking spot stopper (curb bolted to ground) as I backed out. There is obviously some scraping on the diffuser underneath (doesn't look to be the first time ) but nothing else wrong that I can tell. Is there anything that could be damaged inside the diffuser or that I am not noticing? I am most worried of the stress it creates on the bumper and front of the car, since it seemed like it lifted the car over the curb and was resting on it.
