Default Where to buy - STi Springs

Anyone know where I can pick up STi (Spec C preferably) springs for a decent price in Canada?

I hate paying for duty.

Since the 2002 Spec C never left Japan, my guess is they are only available through STi parts dealers. If you can get part numbers, Rally might be able to track some down. Might be a futile search though, since Spec C's were such a ltd. production run. The current STi (V7) is an easier find. No they are not the same springs. USDM STi is lowered 10mm lower than standard WRX. Spec C is 25mm lower than a standard JDM WRX.

Thanks for the info damianq.

I'm mainly concerned about the spring rates as opposed to ride height. The Spec-C's are supposedly stiffer in comparison. I think the SPTs are the same too, but I could be wrong.

Just wish I knew where to pick em up. I could only imagine what kind of rediculous price dealers would want for them.

Spt springs are less than 10% stiffer ovver stock. Spec-C is almost 40% stiffer in front & almost 50% stiffer in back, IIRC.

Actually I do not think they do ship to Canada, if I remember correctly.

I'm in Toronto, ON..

Looks like I'll probably end up getting prodrives instead. They've been rated for 180/180 and a pretty even drop on both ends.. the stock STi springs are still too high for my tastes..

Dave at Rallispec.com .....Instead, we do hope to have a complete technical information section added to our website...but its taking a long time to complete.

Anyway...the information I have (which you are welcome to post) is as follows:

MY01-02 GDB/GGB STi model (rev. A/B) front spring rate (part #20330FE130) -- 33.0 N/mm (188 lb/in) ... no drop
note: this includes NBR, STi Prodrive Style, and STi Limited models)
MY01-02 GDB STi (rev. A/B) rear spring rate (part #20380FE670) -- 30.4 N/mm (174 lb/in) ... no drop
note: this include STi Prodrive Style, and STi Limited models)
MY01-02 GGB STi wagon rear spring rate (part #20380FE680) -- ?? (probably around 31-33 N/mm) ... no drop
note: this includes NBR

MY01 GDB STi Type RA (rev. A) front spring rate (part #20330FE330) -- 38.0 N/mm (217 lb/in) ... no drop
MY01 GDB STi Type RA (rev. A) rear spring rate (part #20380FE690) -- 33.4 N/mm (191 lb/in) ... no drop

MY02 GDB STi RA Spec C (rev. B) front spring rate (part #20330FE340) -- 40.0 N/mm (228 lb/in) .... 10mm lower
MY02 GDB STi RA spec C (rev. B) rear spring rate (part #20380FE790) -- ?? (sorry can't find this at the moment).... 10mm lower


STi rev. A/B Lowering Spring Set front spring rate (part #ST203304S000) -- 35.0 N/mm (200 lb/in) .... 20mm lowering according to STi (20mm measured drop on US sedan)
STi rev. A/B Lowering Spring Set rear spring rate (part #ST203804S000) -- 32.4 N/mm (185 lb/in) .... 20mm lowering according to STi (30mm measured drop on US sedan)
STi rev. C Lowering Spring Set front spring rate (recently released part) -- 45.0 N/mm (257 lb/in) ... 20mm lowering
STi rev. C Lowering Spring Set rear spring rate (recently released part) -- 38.0 N/mm (217 lb/in) ... 20mm lowering

Sorry I don't have any info on the rev. C model spring rates aside from the STi lowering springs.

Stock MY02 WRX sedan front spring rate (very rough actual measurement) -- 150 lb/in
Stock MY02 WRX wagon front spring rate (very rough meaurement) -- 135 lb/in
Stock MY02 WRX sedan rear spring rate (very rough measurement) -- 140 lb/in
Stock MY02 WRX wagon rear spring rate (very rough measurement) -- 145 lb/in

With regards to swaybar sizing....

GDB/GGB STi (rev. A/B) + GDA WRX sedan (rev. A-C) rear bar size -- 20mm
GDB STi (rev. C) rear bar size -- ??... bar size changed but cannot determine sizing from info available
note: both above apply to all STi models including RA and RA spec C.
GGA WRX wagon rear bar size -- 17mm

GDB/GGB STi (rev. A/B) + GDA/GGA WRX front bar size -- 20mm
note: includes RA spec C (rev. B)
GDB STi Type RA (rev. A) + GDB STi (rev. C w/ DCCD) + GDB STi RA spec C (rev. C) front bar size -- 19mm

With regards to strut damping rates... I have info available but don't necessarily see any point in listing it. The important info is as follows:

Rev. A STi sedan and STi type RA models used same front/rear struts
Rev. B/C....all STi sedan models used same front struts (slightly different damping rates from rev. A)
Rev. B....all STi sedan models used same rear struts (also revised from rev. A)
Rev. C... all STi & WRX (JDM) sedan models used same rear struts....changed to accomodate signficant changes to rear suspension.
Rev. A/B STi wagon used softer front strut then sedan (STi wagon no longer available in MY03)
note: the important thing here is that type RA and RA spec C uses same front strut as standard STi for any particular year.


Lastly.... "RA" basically stands for "Race Altered" which means it is intended as a starting point for competition use and is stripped down and with special competition equipment. All previous GC8 models were available in RA trim. This carried over to the first year of New Age body style (MY01) albeit for the STi model only (for GC8 you could get a WRX RA). However, the new car was not recieved all that well in Japan and Subaru felt obliged to make some changes which it hoped would recapture some of the raw agression that the GC8 RA models had. Thus, in late MY01 (effectively beginning with MY02) the RA Spec C was released and replaced the STi Type RA. The Spec C was lightened to the extreme (no undercoating, thinner body panels and glass, many lightweight components) and the suspension was revised heavily with a lower center of gravity, revised front geometry (including more positive caster), revised rear geometry (for reduced roll center), and reduced unsprung weight. Also, changes were made to increase midrange torque (ball bearing turbo, revised camshafts, revised ECU programming...and in MY03 a revised exhaust manifold and twin-scroll turbo).

Hope this answers yours and others questions on the subject. If I find any additional info I will try to pass it along.

Regards,
Dave
