I am not sure what you guys are panicking about.
Both the engine sump and trans sump hang down below the chassis rail in my car, and have never looked like scraping.
Going over speed humps, getting loaded into the trailer and anywhere else is not a problem.
My side pipes are lower than the sumps so they will hit before anything else anyway.
I have however fitted a baffle in my sump which I think is very important if you are planning on doing any track work.
