Same thing happened to me in my first car, it was lowered. Going 70, tailgaiting like an idiot, and I run over a massive rock. When I say massive, I mean it was so big that when I ran over it, I heard a KABOOOOOMMM and the car went airborn. Almost lost it into a guardrail. I also saw a bunch of stuff come flying out from under the car, but I pulled over and it was doing just fine LOL.
