Re: Holes in the rear end of hondas
someone on here explained it in a good way, so ill do it the same way...
your back bumper acts as a parachute, air gets trapped in there as the car moves forwards, parasitic drag= slow car down, holes allow air flow thro the bumper instead of holding it there creating drag. but like "thermal" said street cars have no real use for them.......

Re: Holes in the rear end of hondas
Aerodynamically, wind gets trapped in an under carriage. A diffusers purpose is to allow easier passage of air and minimize drag. Like I said, street cars dont need this. I can agree with full drag cars having this.
Why more Hondas have this? If I answer that, this thread will end up in SPO.
