Except that the DCCDPro controller is stupid easy to hook up and give a 5mt DCCD better maps than the STi has now.

Doing it this way myself....Type UK DCCD unit onto a friggin OBS box(?) with the dccdpro controller. WAY better than any of the STi's I've driven......

all GC8 is 5-100 from subaru factory. R180+ 5x100 was my GC8; all r180 gc8 from subaru factory is 5-100. knuckle and track unchanged, its GC8 suspension geometry.

GDB 5-100 hubs seem wider than gc8 but this still needs to be verified via measuring.

5-114 came out usa in 2005 sti

version 7/8 JDM sti was 5-100, version 9+ in japan was 114.

DCCD for GC8 is stupid, does not adjust on its own (no brain power). default (un-powered) is 65% rear, and its fastest on tarmac/track in dry conditions like that.

Damn, I found some people selling 5x100 R180 GD hubs.
I guess they won't fit then...

There is new one for sale on fleabay currently, not too expensive either.

Wow none of you knew that Ver.4 Type-R and RA = R180 in the rear and DCCD? front axles and hubs are the same. Rear's aren't. Find JDM rear hubs + 2 pots.

Otherwise you're only resort is custom hybrid axles which is just stupid.

 

[JWalker]

Was r180 gc8 first versions 5x100 or 114? Did the knuckle change track or stay exactly the same?

5x114 didn't arrive until '05. Have you ever heard of GC8 5-spoke goldies coming in 5x114? :facepalm:

How arrogant... Of course most people realy into subarus know the 04sti was the only usdm sti with 5x100 and that the 5x114 sti started in 05 in the US, but we're discussing mating older usdm rear parts with jdm rear r160 dccd and/or jdm rear r180 parts. It was already stated that there were gc versions with dccd setups and 5x100 hubs so what is your problem? Do you have something against people trying to learn via public discussion? We don't all live in Japan or know every version of wheel / hub / kuckle / spindle / axle / diff that came with every version jdm wrx.

That is cool. Aftermarket brains is smarts!!

Personally I just like rear wheel drive cars, don't start to enjoy awd unless I'm being a serious hooligan

 

[Mad Ra88it]

Moose dropping mad knowledge BOMBS in this thread!!

That being said... I've got 4 R180 hubs from a V3 DCCD TYPE RA, for sale.

No. I Just expect a bit better information out of some folks posting here. I've dealt 1st hand what OP is dealing with as I've got the same Trans so I can answer all of OP's questions in 2 links, thus sparing him the speculation and misinformation you've provided. (not that I need to b/c supermoose handled that already) cool video though... but irrelevant as it shows a Ver. 2 RA and OP's is a Ver.4.

When in doubt reference your trans code Here

Learn why hybrid axles arent cost effective Here

That said. OP should get the hubs + 2 pots that the Ra88it offers. You can get the Front 4 pots later on when you recuperate.

Version 3 sti-RA is dccd 5 speed trans+r180 and 11" sliding non vented rear brakes.

They are not 2 pots!!!
Version 4 sti-RA went to 2 pot rears, version 3 sti-RA used an in-between setup.

special version 3 sti-RA only r180 size e brake with big 11" rotor; this is a "h6 2000 legacy" rotor - but with big e brake. No USA rotor is conpatible but any non vented disc USA rear caliper IS compatible (ala 2.5rs gc8 USA).

Blakemono had these on his v3 sti-RA imported everything and had to puzzle this out; he probably has a source for part number or aftermarket rotors for sti3ra rear.

 

[2slo4u]

-It was sold to him as ver4, I have no way of knowing he wasn't sold an earliier version and told it was ver4 which is why I asked him to post pics
-the vid I posted was of the early version illustrating dccd was available in those r160 versions, therefore relevant to my statement about early dccd setups using r160 rears
-other people answering after me and not being corrected by me doesn't constitute misinformation, I never told the OP his setup was r160 nor did I tell him r180 axles would fit his r160 knuckles and hubs

Yes, I WASN'T aware the r160 stopped at version 2 which is WHY I stated I "thought" r160 may have been available in later gc8's, possibly the OP's. I never stated his was r160, only that if it was that it would work with his current car. I'm glad Supermoose stepped in to clear it up because there were parts I was unsure of.
None of this justifies your condescending statements either way. The fact that you come in way after Supermoose clarifies things to be an echo is even more douchetastic. Way to go :clap:

I ran jdm gdb 5-100 hubs r180 on my old gc8. Loved it, they fit perfect!!! Swoop my old photos.

Many other members using sti usdm 2004 5-100 hubs happily !!!

 

[ThatGuy]

Sorry, I honestly kinda thought OP was talking about the front diff, as rear is a bit easier to change. I forget not many other people than me care about ALL the diffs, instead of the rear.

Really, that work just fine? :banana: Yay! I'm getting luckier, I found JDM V6 Type-R hubs and found some people selling V7 STi stuff!

Also, thank you JWalker for the links, those will help me reference stuff for later.

And thanks everyone for trying to help out.

+1 but they are non-abs I have 2 pairs of these V3 knuckles (these fit under my 15" wheels) + the 4.44 R180 / DCCD set-up from a V4 STi-R...
&
+1 on the R160 3.9 FD on the V2 STi RA I got one of these + a R160 4.44 M-LSD just in case I go 5-6 speed DCCD & do not want to swap knuckle...

IS there a way to make the V3 STi R/RA Rear knuckle ABS - I was thinking of using hubs/tone rings from a '04 STi...?...

R180 axles are THICK & will not fit into a R160 hub...

GC8 RA's are NON ABS they are RACING WEAPONS!!!!!!!!!!!!
even my old V2 Sti-RA v-limited had Air conditioning but no abs!!
******
reference the forester guys doing 6mt+ keeping ABS, we did this on a 08 FXT+sti 5-114 conversion to keep its ABS; there is some special thingus (aftermarket spacer thing to space the ABS ring) to adap the abs that may work in your situation

 

[Smoke]

I'm also certain that I need the front hubs to fit the axles too, correct?

 

[2slo4u]

Edited because I made a boo boo.

 

[RB2B]

HOLY FRIGGIN CRAP^^^^

The rear axle setup is the ONLY THING that is R160/R180 specific. The front hubs are interchangeable from ALL 5MT's and even the 6MT's. I am current using 5MT front axles in my V5 Type R with a 2005 GDB Spec C 6MT. There is no such thing as a R180 FRONT HUB....

The only thing that matters with the front hubs is the lug bolt pattern is the same as the rear. Unless of course your running some weird setup with different lugs/wheel bolt patterns front and rear...

I have never seen so much mis-information in one thread before.

 

[2slo4u]

Holy friggin crap, I will edit my post. So apparently you don't need 6mt axles in the front, and you can run the same frickin 5mt axles. So if he gets jdm 5x100 r180 rear knuckles and hubs he will be able to keep his usdm rs front knuckles and hubs, correct? And if he uses usdm r180 rear hubs and kuckles he will have to convert the fronts to 5x114 knuckles and hubs then, correct?

Go ahead and jump on the bandwagon with jwalker. So much nasioc in this thread. Sucks some people can't just correct someone rather than throw a fit online.
