The "Will this suspension part fit my car?" thread.
This is a copy from a thread I did somewhere else but it should be pretty useful here too. I'll continually be adding to it as we learn more about the 08 Imprezas.
---------------------------------------------
This is a work in progress and took me a little while as it is, but I think it's a pretty decent start on finally making an all encompassing "fitment" thread. I tried to make it as easy to go through as possible while still covering everthing. It's still a little confusing. Blame that on Subaru, not me.
PLEASE if you notice I'm missing something, don't flame me.....just let me know! I'll change/add it as soon as I can. And yes, please double check my work.
I may rearrange the organization, but for the time being i'm focusing on content.

The following have a specific fitment for 02-03 WRX and RS, and all of the following spring and strut top fitment with these is the same as it is for the stock struts.

To use OEM or aftermarket struts that have a specific fitment for 04-07 RS, WRX, or 04 STi, you must use 04+ style rear strut tops and 04+ springs.
05+ STi struts will not fit.
Wagons are different, see notes below.
Springs
Springs for 02-03 Impreza RS or WRX will fit.
Springs designed for 04+ Impreza will fit on your 02-03 Impreza struts or 02-03 aftermarket struts, but you must use 04+ rear strut top mounts and the Scooby921 strut spacer. Details on why the spacer is needed available here:
http://forums.nasioc.com/forums/showthread.php?t=563382
Scooby921 Strut Spacer available here:
http://turninconcepts10.chainreactio...5e77d30c577da7
Aftermarket springs designed for Impreza STi will be too stiff for stock struts. OEM STi springs work well though.
You can use 04+ springs with 04-07 RS, WRX and 04 STi struts. You must then use 04+ style rear top mounts.
Strut tops and Camber Plates
All 02+ RS, WRX, and STi front strut top mounts and front camber plates will fit the front.
02-03 rear strut tops fit the rear only with 02-03 springs.
04+ style rear strut top mounts require 04+ style springs.
2002-2007 2.5RS, TS, and 2.5i strut tops are softer then both WRX and STi strut tops (which are the same stiffness). confirmed?
WRX and STi strut tops are the same stiffness. STi strut tops are NOT Group N strut top mounts, which are even stiffer.
Camber bolts
All 02-07 Impreza RS, WRX and STi camber bolts are interchangeable and 14mm.
Strut Bars
Front and rear strut bars from any 02-07 RS, WRX, and STi will fit.
Coilovers
Any complete coilover for 02-07 RS, WRX and 04 STi will fit.
05+ STi coilovers will not fit.
Swaybars and Swaybar mounts/bushings
All rear swaybars for any 02-07 RS and WRX will fit. STi rear swaybars will mount on the outside of the endlinks and their effectiveness is reduced.
04+ RS, WRX, and STi rear swaybar bushings will not fit 02-03 swaybar mounts.
04+ RS, WRX, and STi rear swaybar mounts will fit and are an upgrade but require 04+ swaybar bushings.
Front swaybars for 02-07 WRX will fit, except on RS models.
02-07 Impreza RS require a specific sway bar to clear the non-turbo headers. WRX and STi front swaybars will not fit an RS.
Endlinks
Wagons require wagon specific front endlinks.
Front endlinks from any sedan 02-07 RS, WRX, or STi will fit the sedan.
Rear endlinks from any 02-07 RS and WRX will fit sedan and wagon. STi rear endlinks will not fit.
Other
All rear lateral links and trailing arms for 02-07 RS and WRX, and 04 STi will fit, except from a wagon. Rear Lateral Links from a STi will require rear STi endlinks and STi rear swaybar. Also see notes on wagon differences.
All front control arms for 02-07 RS, WRX and STi will fit. See notes on wagon differences.
All Anti-lift kits for 02-07 WRX and STi will fit.
Fender Braces do not fit non-turbo models.
WRX Wagon, OBS and 2.5 TS Wagon Differences
Struts
Struts are specific to the Wagon. While sedan OEM and aftermarket struts and coilovers will fit, you will lose negative camber.
This can be corrected with camber bolts and/or camber plates.
The only upgraded struts that retains stock camber numbers are KYB GR2s and Koni inserts in gutted OEM wagon struts.
Springs
Using sedan springs on a wagon often results in a saggy rear end. Prodrive WRX springs are a notable exception. Wagon specific versions are available from a few manufacturers.
Swaybars
Wagon front swaybars are shorter then sedan and require a specific wagon fitment. Sedan bars have been used successfully in certain cases with certain endlinks.
Endlinks
Wagons require wagon specific front endlinks, unless you swap to sedan front control arms.
Other
Front control arms are different. Upgrading to sedan control arms gives you a wider track. It allows you to run sedan front swaybars, of which there are more choices. It also allows you to run sedan struts without losing negative camber, or you can keep your wagon struts and gain negative camber. You will be required to use a sedan front swaybar and sedan front endlinks. It is recommended to use sedan front axles as well, but not required.
Rear lateral links are different. Switching to sedan lateral links requires switching to sedan rear axles.

Struts
STi Version 8 OEM or STi Version 8 Arai Pink Struts and Ohlins Fixed Perch Struts are the only direct replacement struts for 2004 STi.
Koni Inserts have a 04 WRX fitment; however they will not fit in 2004 STi strut bodies due to the inverted design of the STi struts. They can be fitted to any 02-07 Impreza WRX or RS strut body. Fitting them to wagon strut bodies will result in extra negative camber. This assembly will fit a 2004 STi without issue. See here for install http://forums.nasioc.com/forums/show....php?t=1219607

Struts
STi Version 8 OEM or STi Version 8 Arai Pink Struts and Ohlins Fixed Perch Struts are the only direct replacement struts for 2004 STi.
Koni Inserts have a 04 WRX fitment; however they will not fit in 2004 STi strut bodies due to the inverted design of the STi struts. They can be fitted to any 02-07 Impreza WRX or RS strut body. Fitting them to wagon strut bodies will result in extra negative camber. This assembly will fit a 2004 STi without issue. See here for install http://forums.nasioc.com/forums/show....php?t=1219607
The following OEM and aftermarket struts for 02-03 Impreza can work in 2 ways.
1. KYB AGX
2. KYB GR2
3. Tokico HP
4. Tokico D-SPEC
5. STi/SPT Version 7
Either by using 02-03 springs and 02-03 rear strut top mounts.
OR
By using 04+ style springs, 04+ style rear strut top mounts, and the Scooby921 strut spacer, available here:
http://turninconcepts10.chainreactio...5e77d30c577da7
05+ STi struts will not fit.
Springs
Springs designed for 04-07 STi will fit.
Springs for 04-07 RS or WRX will fit, but will be too soft for the stock struts.
To use springs designed for 02-03 Impreza, you must use 02-03 Impreza struts and rear strut top mounts.
See strut section above for spring fitment when using 02-03 struts.
Strut tops and Camber Plates

02-03 rear strut tops fit the rear only with 02-03 springs.

Strut Bars
Front and rear strut bars from any 02-07 RS, WRX, and STi will fit.
