I need a picture of the mazdaspeed rear underskirt diffuser, without it being attached to the car. I want to know how far forward the "diffuser" bit extends. If it doesn't go as far as I think it does..., might be time to frankenstein one.

anyone have pics?

 

here's my CF one. not exactly sure how this pic is gonna help you.

 

Does your CF one have the exact dimensions of the real thing? I'm looking to buy the diffuser, but I wanna know if I should go with MazdaSpeed's one (which I will do if its functional) or some other make.

 

it is the same, nuke. i hate you!

beers

 

It seems awfully, and desperately small, to provide any sort of function.

Any ideas on companies that make functional racing diffusers?

Like this kind:



and this:

 

i've seen someone that had one like those and wanted to put it on their 8. then they found out it wasn't wide enough. i do not know who made it but i think it came from another car.

 

where can you buy that diffuser

 

the one i have? i got it from JRX Rotary/K2 Motoring, but i don't think they are making them anymore.

 

i believe those might be universal and can probably be found on ebay or something

 

im pretty sure that bottom one is an evo.. right?

 

Get the MS one. It's functional. How functional is highly dependent on the rest of your cars setup and the way you're driving.

And if you're just looking for functionality make sure you get the CF one.

 

I plan to get the rest of the bodykit (I already have the wing), coilovers, sway bars, strut bars and chassis bracing. Should make for a cornering beast.

The only thing that's lacking now is power...

 

Get the front bumper before putting on the rear diffuser otherwise you might make the car push. Too much extra downforce in the back with no extra help in the front.

It was already said that the MS body kit is functional and it works better with the more aero items you install. The other big thing is lowering the car. Less air under the car the lower the air pressure and less lift/more downforce. I hate sideskirts because I think they look ricey but they realy help too. If you have any AEROdynamic questions read this article.

I also wonder how far the ms rear diffuser extends. My guess is that it can be improved but you would have to watch out for the exhaust. You dont want to trap in the heat, so anything that went under the exhaust would have to withstand the heat and be vented.

 

^Hey mate, thanks for the info. The link you provided is broken though...
