Ya, if you want to slam your Mx-3 and make it into a low rider, the MazdaSpeed bumper isn't what you need. It's designed for looks, function and to flow with the lines of the car, as well as the OEM side skirts. I like it as well cause I never have to worry about hitting my bumper on anything, I can just drive normal. There are extreme circumstances, like steep driveways or flat bed tow trucks, but even then, it just scrapes along gently. I finally cracked it a bit on the back side in front of the passenger tires from the U-Haul dolly. Thanks to that bumper it was just able to fit with a few tricks, but it must of hit buncing up and down on the road. It's pretty chipped up from the many miles of driving, so I think it's time to get Oscar to make me a CF MS bumper
If you want to make it lower, search for the home depot lip that Mnemonic mentioned, or you can also get a carbon fiber splitter, and maybe even add some canards
