So, does anyone know if anyone currently makes anything like this for the ek? I belive this is a PWJDM one for the s2000.

What are some thoughts on this? worth it? make much time? etc?

Curious to see what people think/say. :nice:

Thats strange looking piece of kit never seen anyting like that before lol mabey someone that builds rally cars?
 
Makes sense to me...lower drag. Expensive to make and ship. But it would be nice!

Haha, no-one who does rallying would strap an expensive piece of plastic to the bottom of their car, it would last all of five minutes and be of no use!

This is for racing cars, it's a pointless expense for anything less.
 
I'll design and make one if there is a demand for it... :D
 
Slap a Spoon sticker on it Kozy and you could probably retire on the money :p

People really will buy anything...
 
Like what CW said, its for race cars. There is no point in using it for a normal road car as it will get damaged and be a waste of money.
 
Interesting to hear the feedback.

It would be great to get some tests on cfd or even in a wind tunnel to compare results.

There is the potential to cut a lot of drag out of the civic and im sure we could all agree on this. Why not try and add some extra downforce while were at it.

This is Not to say I do not agree with some points already made, and I appreciate their validity.

However I also think that there are very few Luddites here and most will always embrace progress. To me, improving the aerodynamics of the civic just seems like a logical step.

Also the in photo displayed the material is carbon fibre, and also, the video of that ae86 is plywood. Its actually really cool and interesting too, as I imagine it would be cheaper that the $3000.00 pricetag of the password one.
 
@Lynch... You definitely make a valid point... I'd definitely be interested in seeing some wind tunnel reports although it's cost a bomb to research but I can't imagine some plastic should cost that much for someone to DIY job and road test it... I'd imagine this would also be a nice protection against rust due to salty roads for the UK guys? Just a thought, but obviously at the same time probably wouldn't suit a daily driver :D

Interesting topic though...

In all seriousness I was thinking about building one of these out of sheet aluminium, OK so it wouldn't be CFD tested (I could do this but the time involved is immense) but a basic undertray extending to the rear bumper could drag at motorway speeds which would work to reduce fuel consumption and improve performance.

To create any kind of meaningful downforce would be a little more involved, and as mentioned, pretty pointless for a road car, could be an interesting project for a serious trackday motor however.

Hell, if I were so inclined, I have the means via work to exactly replicate the EK bodywork, creating a millimeter perfect CAD representation from which to run CFD analysis and create proper calculated aerodynamic parts.

Sadly I don't think there is enough call for it and the equipment in question is bloody expensive, it could be done though...
 
Although it would be nice, im not sure we will ever see a wind tunnel analysis of the ek9. Wind tunnel time is not cheap.
A more likely alternative is analysis on some CFD software, and this may yield some interesting results.

Yes It can indeed be done, but as you have said, it would be more for personal satisfaction as the time and effort involved is significant.

flat bottom is great for more top speed and high speed handling. Still i am dubious about its effects on temperature, which is bound to rise with this construction
 
here some interesting stuff about flat bottoms

i want to make my self a front splitter these days something like this
