And the "regular" one has the flat bottom of course. Anyone know what these are? Are they modded? Did the 2nd pic just remove the bottom plate piece?

Those are pictures of a 63 coupe and a 63 suv. The diffuser of the 63 is different from the 63S. The S has a splitter for better air management and thus less lift at higher speeds.

I couldn't really tell at first what's going on there because the picture is very small, but upon closer look that looks like an aftermarket diffuser and spoiler. I'm only counting three fins. The OEM diffuser has four fins.

The first picture is a coupe with trailer hitch . To be able to accommodate the hitch ,the middle fin is removed and that's OEM .

All 3 are stock and available for 63 base, coupe and S
First one with a hitch
Second, no hitch
Third, with aero package option, it should also have a slightly different front lip upfront.
If you want a hitch, you can't get the aero package.

I have aero package and my diffuser is the same as the 63S model (I have a 63 SUV) and it is black. Aero package also has a slightly larger front lip.

I hope you are interested in the look and don’t expect the diffuser to actually be functional.

Kenny can you post a photo or two?
I am interested in the aero package but the online configuator shows a chrome bar when the aero package is added.
Can you also show how the front of your car look?
