says 09-13 Impreza/WRX. I believe the STI's are the one's that you may have to mod a bit. There is more info in the forum...prob be a good idea to search the member builds.

I'm more than likely buying the Peddlers springs which install directly on the stock struts, and have a lower stance than the Swift springs. WRX suspension is slightly too aggressive for me...being from NYC there's no such thing as flat pavement.

I wanted to chime in here with info and pics on correcting the suspension geometry when going to WRX/STi levels on the 09+.

I've wondered for a long time exactly how Subaru "lifted" the 08+ Impreza to create the 09+ Forester. Previous generations had subframe risers in the front and taller subframe in the back.

Some people have said there are no risers, they just installed taller struts/shocks... I found that hard to believe.

I havent seen anybody really document how this was done in the 09+ (sorry I'm sure its been covered).

I had the opportunity to have an 09 WRX on a lift right next to a 2010 Forester.

Here we go!

Forester front control arm rear mount:


WRX front control arm rear mount:


Forester front subframe to chassis mount:


WRX front subframe to chassis mount:
(sorry bad pic, but you can see there is no spacer there)


Forester rear subframe mount to chassis:


WRX rear subframe mount to chassis:


So thats all I got right now. I'm sure there might be a few more little details to fully convert but someone will need to blaze that trail and document it all.

If you want optimal suspension performance and handling on your SH at Impreza ride heights, you'll really want to look into making these changes to correct suspension geometry to improve your camber curve and roll center.

Again sorry if this has been covered... Hope the pictures are helpful.

yes please. I usually have crap in the back due to driving the family around so right now i have some definite sag. im leaning towards the 1" but i can always change upon install since it seems like its super easy to do

If that is the case go with the 1" spacers.
If you run a little rake when not carrying then so be it but then it wont have super sag when things are in the back :biggrin:

I've had a few different setups...

On my 1st Forester back in 2010/2011:

Setup 1 - Gen 4 Legacy (Liberty in Australia) Bilstein front takeoffs with 08 STi rear take offs. Rode very nice, handled well, but the rear 08 STi spring was not up to the task of supporting the Forester and started to sag over time and bottom out in the rear. Replace the rear springs with something like Pedders and you're good to go.








Setup 2 - Kido Racing Coilovers. Rode very very firm, handled insane, but the ride quality was a little harsh for daily commute on Sydney roads. Perfect for track though!


On my Current Forester
Setup 1 - Gen 4 Legacy Bilsteins with Gen 4 Legacy STi pink springs plus 20mm spacers up front, 2010 STi rear struts with Gen 4 Legacy STi Pinks in the rear. Setup rode and handled very well, firm yet fine for daily commute.





Setup 2 - Same as setup 1 above, but STi pinks replaced with Pedders Gen 4 Legacy springs in the front and Pedders Forester Springs in the rear. The ride was very comfortable, handling is great. A little less firm than with the STi Pinks.





Setup 3 - JDM Gen 5 Legacy GT Bilstein B14 Coilovers. Rides and handles extremely well, arguably the best 'all round' suspension I've rode on in an SH to date.



I've had a couple of other setups that I've helped other people out with too, but didn't have the pics on hand to show height. If you would like more info on anything, just ask :icon_wink:

Jaring. I liked how the stock strut and spring rode, just didn't like the height and wanted it to firm up a bit. The STi is too firm for me. Contemplating a softer coilover or 09+ WRX strut with RCE springs.

Thanks for clarification. I feel like the wrx setup rides the same as as oem fxt 90% of the time fwiw. I plan on adding either RCE or Epic engineering springs to stiffen it a little/lower a tad.

Very helpful sooblover! While i dont need "optimal" susp perf on my way to the grocery store, work, DDing (as much as i would like it!) Ive looked at those on my forester and tried comparing to WRX pics ive seen of the areas in general and thought the same things. thanks for sharing...more research time!

I need some opinions. I'm getting a 2014 wrx setup and don't k ow what size spacer to run in the rear. Should I do 3/8 or 1"?

Sent from AutoGuide.com Free App
3/8 for sure man. obviously it depends on if "cr#p" is referring to 30LBS or 300LBS. When i load up a bunch of stuff in the back, 99% of the time its little in comparison (heavier/bigger things going up top). When ive had a freezer chest or 10 or so mulch bags in the rear it sagged/rubbed a little over big bumps...but im not driving around like that. It's a point A to point B only trip only. plus both of those times were before i added my 3/8 spacers....well see what happens now.

I have had the bcr coils on for about 5K now with swift springs. They are ok for most daily activity, but a recent road trip up north proved a little much for me...
Have you found "the perfect" damping rates on the 32 way adjustments? I have about a 1.5 finger gap all around and wouldn't mind going a bit lower as I am running 18's/235/45, but they are stock 48mm offset, just 8" wide(no rubbing)
thanks and nice foz!

Damn dazzz.....great post man. Question, what was your spring rates on the JDM Gen 5 Legacy GT Bilstein B14 Coilovers? Great looking foz btw as well....excellent taste in wheels, well done!

Hey mate and thanks! I have had no personal experience with BC coilovers TBH. But with Kido coilovers, it had 40 levels of damper adjustment yet I never went above 10. It's very subjective to personal preference on what one may consider to be good, but I never really found a sweet spot for them... maybe I'm just getting old hahaha!

I have to say though that with the Bilstein B14 coilovers, the ride is superb. Super fast damping, comfortable, and handles awesome at the same time. One thing to note though is they have no damper adjustment.

Damn dazzz.....great post man. Question, what was your spring rates on the JDM Gen 5 Legacy GT Bilstein B14 Coilovers? Great looking foz btw as well....excellent taste in wheels, well done!
Thanks man! The Bilstein B14 spring rates are 6kg front and 5kg rear with 1.5kg helper springs all round. Just want to mention the rear height in my pic is as high as it goes without affecting spring preload. The fronts still have 10mm more.

^^^^i just want those spats!!!!!!

Jdm ones Sean. From Japanparts etc.

Dazzzz...can u still use the front spats with the jdm sides????
I don't think you can pair up the front spats with the aero side skirts. We have a set of front spats for sale and could test fit them on a local (Michigan) SH Forester. Anyone in the area want to help out?

Here is some more info on the spats and their fitment: http://www.subaruforester.org/vbulletin/f153/09-13-sh-forester-jdm-aero-spats-set-fronts-only-rears-have-been-sold-221954/
