SWAY BARS FOR STI

Default The "Will this suspension part fit my car?" thread.

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.

Wagon Differences


Struts

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.

1. KYB AGX
2. KYB GR2
3. Koni Inserts (not a complete strut, see here for install http://forums.nasioc.com/forums/show....php?t=1219607)
4. Tokico HP
5. Tokico D-SPEC
6. STi/SPT Version 7

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.

Im using 04-07 STi rear endlinks on my 04 wagon front sway. Theyre Whiteline Spherical endlinks. I just had to drill out the holes in the steel control arm to 12mm, which was cake. Since theyre length adjustable theyre pretty modular.
Aaand you can pretty much 'make' Whiteline Spherical ripoffs with parts from mcmaster.com or equivalent.

Hi everyone,

I have a 1996 impreza outback with stock kyb struts and stock springs. I know that the wrx wagon 02-03 springs will fit with the wrx rear top hats on my car. However, will 2007 wrx wagon springs fit on my wagon with the 07 rear top hats? Or will I need all four top hats?

Let me know guys, thanks!

Waitaminute.... why would this be the case?

Assuming the bar mounts outside the endlink instead of in does not (effectively) change the leverage arm length, approximating that the endlink is roughly in the same orientation (which would especially be true if going from RS/wagon sway bar to a STI one), then the effectiveness of the sway bar would be essentially the same regardless of the connection point.

It's not the mounting that changes the effectiveness, it's the fact that the STI bar is longer (which requires the change in mounting).

I've been told by big knowledge people (Turn in Concepts, Kartboy), that the reduced effectiveness is so minimal, that you can not tell the difference. So in other words, don't worry about it at all.

I've been getting mixed information. Some say WRX springs will fit some say they won't.

04-07 WRX or STI springs will fit.
The STI are probably a bad match for your stock struts.

Springs for 04-07 RS or WRX will fit.

Aftermarket springs designed for Impreza STi will be too stiff for stock struts. OEM STi springs work well though.

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

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 02-06 RS, WRX, and STi will fit.

Front strut bars for 02-05 Impreza fit the 06-07 WRX but with some difficulty regarding the AC lines. There are a few 06-07 specific front strut bars.

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 are an upgrade but require 04+ swaybar bushings.

Front swaybars for 02-07 WRX will fit, except on RS models. Wagons are different, see notes below.

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

Front endlinks from any sedan 02-07 RS, WRX, or STi will fit the sedan. Wagons are different, see notes below.

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. Control arms are aluminum for 06 WRX, but fitment remains the same. Wagons are different, see notes below.

All Anti-lift kits for 02-07 WRX and STi will fit.

Fender Braces do not fit non-turbo models.

2006 Impreza and 2005-2007 Impreza STi use the same steering rack bushings. All other applications will not fit.


WRX Wagon, OBS and 2.5 RS 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 retain stock camber are KYB GR2s and Koni inserts in gutted 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 front 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 a front swaybar, 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 sedan front swaybars 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.
Wondering if you would know If 06/07 WRX Wagon Springs would fit on an 07 STi?

They will physically fit but will be very poorly matched to the shocks.

They will physically fit.

The struts will be under sprung (springs over damped).

You may have a slight lift in the rear.

I have a 2005 wrx wagon. I'm planning on replacing the front LCA's and rear lateral links with sti parts. Would I be able to get away with running sti struts with the wagon springs to avoid saggybutt? Or should I look into sedan specific coilovers? I want to do a full sti swap as the funds come in. Starting with the suspension. I also plan on eventually doing the sedan rear fender conversion. And I have purchased a jdm front clip for the front. Thanks.

I have 2013 wrx sedan and I was looking to buy Koni Sport Struts and I found a kit with the Koni struts and Eibach springs but the kit says its only for 2008-2010 wrx. I emailed the seller and they told me they don't know if it will fit a 2013. Do you see any way it wouldn't fit since the springs definitely fit my car and the struts would too.

It definitely fits your car. The only minor snag will be if you attempt to get oem front camber of .4 that wont be possible. Reason is the front strut clevis tabs on the 08-2010 WRX had a smaller offset. The 2011-2014 WRX had a greater offset due to the "widebody" fenders and shared STi steering rack AND front swaybar/ control arm (width) . SO.....your minimum front camber on your 2011 WRX with those 08-10 Koni struts will be -1.0 minimum and -3.0 MAX!

For most enthusiasts the later camber specs are MEGA awesome since those are camber plate range camber numbers. And lets face it, most Subies come alive around -1.0 front camber.

If you decide you do want the ultra boring stock front camber specs then use some Whiteline camber bolts and that should get you back to stock front camber levels but be prepared for the same amount of understeer as stock since you will have stock alignment specs.

Hope that helps!

Yes your wagon springs will work fine, it will be quite a bit stiffer since the STI struts are stiffer.
