Lotus Elise Diffuser

Yes. That is what I want. I also love the famous white FR-S with the aftermarket elise diffuser. I like the FT86SF diffuser but man, I would rather struggle and sweat over making mine have a diffuser tucked into the bumper like that, with a nice center exit exhaust tucked right above it.

Quick question on rear diffusers in regards to aero.

By changing mufflers from stock (suitcase type) to something like a Invidia (can type) exhaust system, does it really reduce the amount of downforce available that it garners an installation of a rear diffuser?

MaximeT · 09-08-2016, 04:57 AM

It won't change downforce, because OEM diffuser is fake. But it will turn it into a parachute.

My understanding is that the stock muffler does not add any downforce but that it reduces lift, that may be a bit technical but an important distinction. The stock muffler fills up that cavity and creates a relatively smooth undercarriage. By removing the stock muffler and going with many aftermarket type mufflers, you remove that smooth undercarriage which causes turbulence as the air doesn't flow smoothly, which increases lift. Adding a diffuser eliminates this, plus it is more effective than the stock muffler and reduces substantially more lift and can theoretically add additional downforce. The Velox guys can help explain it better as they have done all the CFD work.

Sorry for the bad pic only one I got before the camera battery went flat but was inspired to make a diffuser from looking at this thread .

Would make a few minor changes if doing another one.

Did you notice a difference? Oh and did the panels quiet up the ride? As in noise while driving on say, the high way? Thank you
