Yo Franko,
It depends
It depends on the height of the motor mounts: brand & ride height of kit; also brand and style of pan.
My E-M with the Canton 7-quart road race pan has no problem with clearance - within reason of course. Speed bumps and potholes are negotiated with care especially if I have a large passenger aboard.
The lowest point under my car is not the engine pan. The C-6 finned aluminum deep pan for the transmission hangs down about an inch below the engine pan, and has been known to protest if I forget about the big bumps. So far no leaks
The trans pan is low enough that I have had the drain plug replaced with a hex plug so the bolt head isn't the lowest point any more
Depending on the total car, some folks have a bit more problem with some of the exhaust parts or even the bottom of the bell housing scraping.
Regards,
Tom
