Most of my cars are low.. probably lower than yours..

I avoid speed bumps, even if I have to walk a long distance (which isnt easy for me) or drive a few blocks around them. Also have to watch out for roads that have low spots where the tires are, and high spots in the middle. I gotta drive on the high spots and hug the outside lines or the inside line. When I do get stuck witha speed bump that I cant get around, I will go over it at an angle, if you get enough angle the headers will come up far enough to clear the bump.
Had one at the entrance to my apartment complex. Since the sidewalk was higher than the speed bump and it was on both sides, I would just run two wheels on the sidewalk and two over the bump. Headers rarely touched doing that..
I always find it amusing when someone has a 4x4 with big tires and about 10-20" of ground clearance, slowing down and creeping over them like they are going to rip the oil pan off the Escalade/Excursion or whatever it is.. then they flip me a bird because I go over them sidewayz..
Oh and welcome to our world!
