Porsche parts on a Civic..How do people even come up with ideas like this?

you'd think!  control arm mounted air deflectors are actually a pretty common OEM part.  the Focus SVT and GTI guys were using this Porsche trick years and years ago.  i've heard of other guys adapting it to their sport compacts of differing brands as well.  

Porsche's part just seems to be a good fit for a lot of platforms and is filthy cheap for whatever reason.
