my 95 has H&R's and Tokicos and the splash guards sometimes scrape on speed bumps. Also the bottom of the front bumper sometimes scrapes on driveways, but aside from that, nothing too bad.

 

I had my Y-pipe replaced a few weeks ago, and the scraping stopped. Although, I also began driving a little more carefully (ie, riding the sidewalks when I've got 4 people in the car). I'm not sure if it'll scrape when I have the-cheese-style-lowering (ie, 600lbs of people in it), but for the most part, I haven't heard a scrape on the bottom since the installation. Some pipe down there just likes to hang low. Take a look under the car to see what it is =)

 

Either these speed bumps are HUGE or you've got a problem.
Mine is lowered and even with a full load I don't scrap speed bumps as long as take them at an even pace.
Some inclines get me but that's it.
Sound like something hanging low man.

your catilytic converter shield is probably hitting it, thats all. Or you're driving too fast over them
