I have a 2010 Honda Civic, I ran over a curb at about 6-8 mph, the bottom of this car, as you know is really LOW, it made a loud scraping, banging noise. There's no apparent damage, HOW STURDY are the frames on these things, did I do any damage???

 

curbing at that low of speed wont do much damage to your frame, but can damage other things like tires,rims, suspension parts. are you having any issues with the cars drivability ???
