I'd love to lower mine, but have I have a rolled curb apron at the end of my driveway. I purchased a Bridjit curb ramp and still barely miss scrapping the bottom of the splitter when I leave and enter the driveway. No way could I lower an inch and not have some major clearance issues with my drive.
