a lot of aerodynamic modifications are indeed made to reduce wind noise and watter flows. and therefore not nessesary reduce drag. i can't imagine the original bulges being there for noise reduction.

what i find odd is that recently a lot of independant manifacturers seem to have come up with a simalar solution... but to what problem?... wheel have changed fairly little since cars first came out. sure they contribute to drag but how does a little bulge all of the sudden solves that...
