Must be the different areas we live in. I am from Markham Ontario and the roads are pretty good here. I have also been driving "low" cars for the past 15 years so a little bit of experience as well. My lip does scrape at times, no mud flaps for me.How do you not bottom out constantly?
Mine is stock height, and my front splitter and mud flaps bottom out on every speed bump and non-flat driveway.
