H Kansai Service rear underbody diffuser - I want!
Anyone know who can import one of this
pricey @ nearly $690 but it's awesome
Wish a vendor would have a replica made....

Looks better than the '06 STI diffuser IMO

That is an awesome diffuser. Exactly what I have been looking for. I want one too!!!
engineerx 06-17-2005 02:15 AM

Yep - sure looks similar to the Jun Lemon Dragon's rear diffuser, which I think is plain awesome.
The HKS diffuser looks alot more agressive than the optional/stock factory rear diffuser of the '06 STI. Damn ... it's about Y69,090 (~ $690) + add freight & markup! yikes!

engineerx, your supposed to keep those kind of items secret. :) i've been watching that thing for like a month now, and i see they finally put a price up, before it was just coming soon.

I want one too. I emailed visnu about a Scooby version of their evo one... they said its in the works.

i want one !!!
paperchasin 06-17-2005 11:26 AM

shipping that piece must really hurt the price too....
tool1128 06-17-2005 11:28 AM

I want one!
WikdRX 06-17-2005 11:30 AM

kinda pricey but i still want one
leoflc 06-17-2005 11:36 AM

I wonder how fast you really need to go to feel the difference...
But looks cool!
mbiker97 06-17-2005 12:11 PM

They added a lot of underbody cladding, much like a Toyota.
engineerx 06-17-2005 12:34 PM

[QUOTE=leoflc]I wonder how fast you really need to go to feel the difference...
But looks cool![/QUOTE]

You definitely need to have fairly clean flow under the car, if it's too turbulent it really will not be making much difference. That's why the new 06 STI has all those underbody panels to promote smoother airflow under the car (and so do many supercars like Porsche, Ferarri, etc)

You would need to do wind tunnel testing or attach those strings before & after to observe how the flow behaves

Regardless.. I think it looks cool and would make any1's WRX look great... One of those mods that's more for the looks.... I want it ...
I sent it a request for quote to a Japanese exporter - I don't know if it's already available, hopefully the exporter will get back to me - I'll post the info here.

[QUOTE=drivrswntd]engineerx, your supposed to keep those kind of items secret. :) i've been watching that thing for like a month now, and i see they finally put a price up, before it was just coming soon.[/QUOTE]

:lol: I know... but I figure eventually some would find it .... gotta get dibs on 1st post hahah!!
At that price .... I don't think you'll see that many of those around.

As I said - It would be great if a vendor would have a CF shop make a replica and sell it for $300 - $400. I think it would sell. I paid $300 for the RavSpec front CF STI S203 lip replica and this rear diffuser is all flat shapes so not too difficult to lay the CF once you make the mold
distorto 06-17-2005 12:44 PM

that is exactly what i have wanted since i bought the car...

Not much negative pressure (downforce) generated by our 4-door sedans :(

[QUOTE=mbiker97]Interesting how the new exhaust goes under the rear axle instead of over it. I wonder why they did that. They also added a lot of underbody cladding, much like a Toyota.[/QUOTE]

the exhaust has always gone under the axle :huh:

In case anyone is looking for a source Bulletproof Automotive imports alot of HKS kansai service parts. I've used them before and they're great. [url]www.bulletproofautomotive.com[/url]

I was looking on Kansai Service's website the other day for *another part* (thanks for drvrwanted the reminder haha ;) :p ) and happened to see the diffuser too. Neither of them are on Bulletproof's site yet since its new but probably will since they carry just about everything else they make...
dead-eye 06-17-2005 03:26 PM

Sorry to get off-topic, but does the HKS Kansai Service GDB airduct fit the GC8? It looks great.

Myles gets the cool stuff all the time !

Damn ... I wish I was still in school - I had access to CF / structural adhesive / aluminum honeycomb / epoxy / vacuum pumps / well everything needed to make parts....
I built so many CF parts... I think I still have epoxy and CF shards in my skin (that stuf is itchy!) Well I help build and race this:

Yep! we were fabricating CF parts & wheels back in the mid 90's way before they became popular on Subies :lol:

ChrisL2 06-17-2005 05:07 PM

So pretty. Too bad it might not work with some aftermarket exhausts.

I actually don't think $690 is a bad price for a CF version. Shipping will hurt a little though.
WRX8XB 06-17-2005 05:18 PM

they mentioned something about having to modify it for some exhausts.
vaj 06-17-2005 11:36 PM

That is sweet. Lotta cool aftermarket pieces out there. That one takes the cake.

Very nice. Thanks for posting that. I kind of figured that's what it was supposed to do, but I wasn't quite sure.
engineerx 06-18-2005 12:22 PM

Here's one quote ~$400 airfreight is not too bad...
Anyone know any good surface shipping company for Japanese imports?

or Myles @ Racecomp Engr - will you be oredering one for yourself soon? However I still need to check my finances..... I've been spending major $$ lately with the APS rotated mount turbo + internals + Hydra EMS install....and I sitll have to pay for tuning


[QUOTE=WRX8XB]they mentioned something about having to modify it for some exhausts.[/QUOTE]

Yes - most likely that will be the case if you have anything bigger than the stock can - if you have an exhaust at an angle , it may still fit but trimming will no doubt be required.

It would sell very well if the price is decent. Lots of interest for this part.
The part is not all that difficult to make - mostly flat shapes
AZ-GT 06-21-2005 02:15 PM

am I the only one that thinks it looks too thin, almost like a sticker, at least on the part where it sticks onto the bottom of the bumper.

If you guys want these, I can get it. Email me your request or questions [email][email�protected][/email]
engineerx 06-22-2005 05:05 PM

Well, you don't want it too thick where it attaches to the bumper... and it doesn't need to be overly thick.. as it's not a skid plate or to protect your underbody. If properly made, 2 - 3 layers of CF should be strong enough. If you're referring to the Vortex generators/ vertical fins.. those don't need to be thick either.

I wish they had wind tunnel pics showing the airflow before & after with decreased boundary layer separation- that would definitely convince me to buy it, otherwise it's just a "bling" piece I'd reeeeally love to have ! :D

i'd like to see better pictures, especially of the CF version before i ploped down $750. Does look very inticing though.
