What’s with the rear spoiler?

[Moparfiend]

The rear spoiler alone does nothing, you need the full package to notice any aerodynamic gains.
And treated lumbar is a plus.

Treated lumbar support…ouch! But the lumber siding is sweet!

For me if it was an option to have the go wing. Always. I love them personally and I don't care if they work even .1%. I think they make the car look the way I envision when I start the build.

Re Jeff Peteson full Aero Treatment pic:

It is a "natural organic" carbon fiber you must admit.

I bet that car really hugs the road with all that added weight down low. That is once you finally get it moving.

Front and rear spoilers. These provide negative lift for greater traction and control - particularly at high speeds. CODE A45 - front and rear. CODE J81 - rear only.​

Quite ugly and not doing much from aerodynamic side.
Yes optional

it was an option available J81 from the factory. No functionality, it was added for looks only. Some people like it and some don't.

I would never insult a guy's car unless I knew him and we were good enough friends to be comfortable insulting each other.
I do not like those Go-Wing, Gull-Wing, spoilers or whatever they are. The 1970 E body rear spoilers were cool though.
No offense meant but the green Plymouth above does not look right to me with that spoiler. It looks too narrow for the car. If the owner likes it, that matters more than what anyone else thinks.

I bet that is the "cat's meow" mounted as a "spoiler" CODE A45 on the front.
It's all about looks anyway it seems, it surely has nothing to do with even using a proper name.
