Honestly if I didn't scrape I'd be afraid something was wrong with my car. I have literally worn off the heads of the bolts that hold the back of my aluminum undertray on. they need vice grips to get off, but I can change my oil w/o taking off the UC so it's all good.

As Marcus once said "There's no such thing as too low, the ground is too high".

 

I'm so used to my 05 silverado with a 4/6 drop scraping that when my G first scraped I wouldn't have noticed if it wasn't for the wife telling me
