More suspension than you can shake a stick at. - Page 2

Well I will just put my two cents in and leave it at that as well.

Subaru DEFINITELY distinctly color codes their springs for different models. I have that info right from the horse's mouth(Subaru Japan) via a friend of mine in Japan. The color codes on the set above is for specifically Ver8 "regular" STi sedan takeoffs. The reason I know that is because I bought the same exact setup off a "regular" STi Ver8 RevC home. I know the complete lineage of the setup. The setup StevieD posted we are 95% positive is the RevC spec C setup. I am positive the paint codes on the set you have posted originated on a Ver8 "regular" STi.

Dont mean to hijack and all props for your work as appropriate, but you might want to shoot SoJ an email(or have it done or your behalf) to try and clear up the confusion.

Looks like I opened up a can worms in here.

Chaste---Please at least answer my question about the differences between V8 Sti spring, strut and tophats and those of the V8 Spec C. Do you have a contact at Prodrive where I can confirm these are Spec C?

As an off note....lets all try and play nice.

MK2TMR2 · 03-25-2004, 07:01 PM

Aren't there different trim levels of the STi Spec-C? For example:

That is a stripper model of the Spec-C. Steelies, no Brembo brakes, standard impreza interior and, perhaps, regular STi springs.

http://www.subaru.co.jp/impreza/wrx/08/03_c.html

Just curious if perhaps these struts/springs did, indeed, come off a Spec-C - but they are not the uprated Spec-C springs that command a $200 premium over standard JDM STi takeoffs.

The "stripper" model or 16" model STi spec C is identical to the 17" STi spec C in terms of suspension. You pretty much named most of the differences between those two models - wheels, tires and brakes. It also lacks even more creature comforts than the "regular" spec C

What kind of adjustability does the STi V8 suspension have? Are they ride-height or damping adjustable from factory? I don't know too much about them.

afaik, the only adjustables from STI are the pinks.
I have regular v8 JDM stuts/springs/hats and i love them over the stockers.

Chaste Automotive · 03-28-2004, 07:49 PM

Suby south since your friend at SOA says that they are different can you find out the exact spring rates? When I get back from Europe I would be happy to dyno the various springs but if your friend knows we can have a baseline to go from.

Chaste Automotive · 03-30-2004, 11:34 AM

no response Suby south ? willing to work with you.

That would be a GREAT service to the community!

It amazes me that with all the bits of information floating around, no one knows the actual V8 Spec C spring rates. The common wisdom seems to be that they're about the same as V7 Spec C rates, but I think that's just conjecture.

Chaste Automotive · 03-30-2004, 12:11 PM

Yeah since he has a friend at SOA japan I think that he could get the factory numbers and then we could go off of those for a comparison. All spring manufacturers use dots to indicate spring rates, now that said I have more than a few sets that are not corresponding and they cam off the smae car. I see all the cars before they are parted out so have the advantage of knowing where my stuff comes from as opposed to buying stuff from japanese junkyards and Yahoo auctions. I am willing to figure this out just need some help from everyone else there is no sense in testing them without a base figure so we can decide which goes to which model.

StevieD · 03-30-2004, 01:16 PM

Some info here:

http://www.northursalia.com/t...ng/spring.html

Not complete thoough.

Chaste Automotive · 03-30-2004, 02:13 PM

thank you, I will have a look at that but it does not address the current issue unfortunately. Do you know how those rates were measured?

subysouth · 03-31-2004, 10:10 PM

Sorry just got back to this thread.

All of the info in the above linked takeoff thread was oriented towards JDM STi takeoff suspension assemblies. When that thread was started there was no USDM STi in the picture yet. I have no idea what the paint codes or spring rates are for the USDM STi. If they matched a JDM spring code we could speculate perhaps.

My friend got the paint code info direct from a guy at SoJ not SoA. Also the guys response (and apparently Subarus general response) to his query about rates was that Subaru doesnt guarantee any specific spring rates or something along those lines. Meaning they know the rates they were going for on the models but dont guarantee them. Something to do with spring rate variation inherent to the manufacturing process I think.

And this point is beside the point of my post above. My post was dealing with the fact that Subaru does color code the springs for the various models. The guy at SoJ did verify this. The codes that we know have come from a process of elimination from spring sets from known cars and by cross referencing part numbers and in most cases they have been verified several times over. The spring code in the pic above I personally have verified the lineage of because I purchased the same exact set off a known vehicle. From my experience its from a Ver8 "regular" STi.

And its a fine setup. If it would have worked on my car I would have kept them.

If you have the time and access to a spring dyno, let me join the list of people thanking you in advance for any info you could share on the actual spring rates. That would be a huge help to the club I think.

BriDrive · 04-02-2004, 03:17 PM

subysouth,

I had JDM version8 (revd) struts and type-c springs. I understand Chaste Automotive's pain because:

The type-c spring I mentioned above shares the EXACT paint code of the USDM STI springs....

One way to verify (albeit a PITA) is too install both on the same strut....the type-c spring we are talking about here in this version/revolution is 10 mm lower than a US STI spring...front and back......

I have posted several times in this regard and am convinced that Chaste Automotive has what he is saying and further in the latest spec ( V8 revd) you can't go by the paint code only.

Chaste Automotive....call Mike Shields and ask him where his
type-c's come from....He'll tell you the same thing you've experienced...........

My point is: if you trust your source and they KNOW where they are getting thier type-c's, then you can be sure you are getting the right rig..........If you buy V8 type-c from a private party its a bit of a crap shoot if you are ONLY going on aesthetics......

BriDrive

StevieD · 04-02-2004, 04:21 PM

GDB-D Spec C are Green up back and Red , Green and Blue up front (To the best of my experience)

... but there's a lot of qualified folks bring up good points about using a spring rate compressor to be 100% sure

StevieD · 04-02-2004, 04:22 PM

Hope you can see this better:

Free bump for some nice parts!

igalwrx · 04-02-2004, 04:45 PM

In the installation instructions for the dealer supplied SPT suspension (V7 STi Ra I think), there is a drawing of the spring and they point to the paint markings and label it "identification paint". Take from this whatever you want.

Chaste Automotive · 04-07-2004, 11:50 AM

Okay just got back from UK last night and here is what I was told by the engineers at prodrive. Now first last year the Group N homologated car was the Spec C and not the RA, this year it is the RA and not the Spec C. I do not have any of the struts from this year so that rules out my stuff being from the RA. Now next thing I have struts with all different combinations of paint codes. Now all the V.8 stuff I have came off the spec C cars but some of the sets have different colored dots even thought they all came off identical spec cars. This leads me to believe that the ID dots are not indicative of spring rates but production runs, I could be wrong but this seems to be the logical explanation for different colored dots. We are really busy but I have a suspension dyno I can use so if we geta chance then we can put this together and finalize something. FWIW not all RA struts have the same numbers either so go figure that. Now what people have to use is the complete part numbers (this includes engines because a lot of people use incomplete engine numbers so we are all talking apples to apples and oranges to oranges)
