Some cars will, some cars won't. Just depends on how low and the distance from the wheels to the edge of the front bumper (the longer more chance of scraping). As I said my car at stock height *just* clears [a similar set of ramps] without scraping...and I have to be pretty careful. I don't really have a lip as another piece but my car does have an extended bumper with sort of a built in lip you could say. If it's a multi-piece bumper you have, and it's low, I probably wouldn't try it.
The good news is they're made of plastic so even if it touches lightly, there shouldn't be much of any damage. Of course mine have a "surfaced" top, whereas these have the open top and the support spars (or whatever you want to call them) exposed. That may be a little worse if it scrapes.
