It depends on if they are standard size speed bumps or like speed humps or something. I have done that a few times but it was either because I went too fast or was in a hotel parking lot. They usually make them higher than usual.

 

I'm stock in terms of suspension and wheels, and no problems around here with speed bumps.

 

i got steeda shocks, struts, and ultra-lite springs. never scraped yet. that is including all those crazy driveways, ramps, speed bumps, parking barriers (talking about my front bumper clearing).

visually, a lower drop would look nicer, but it is nice not having to worry about scraping anything.
