I don't get it

OK I will try to explain.
In the USA there is a show called "Pimp My Ride" and the host is Xibit, a rapper. He's the one pictured there.
The theme of the show is outrageous mods to real peoples' rides. So for example a guy who loves to cook might get an oven put in his van. At some point Xibit said something like "Yo dawg I heard you like to bake so we put an oven in your car so you can bake while you drive" (Not the real quote, but the principle is the same).
This has become an internet meme only it's gotten a little changed where the format is "yo dawg we heard you like X so we put a Y in your Z so you can A while you B" The meme has kind of transformed where Y and Z are the same thing. So for example "Yo dawg we heard you like to bounce so we put a spring in your spring so you can bounce while you bounce" or something.
So the caption for this pic might be something like "Yo dawg we heard you like downforce so we put a wing in your wing so you can generate downforce while you generate downforce" or something.
