Lowering SH Forester options

STILL UNDER CONSTRUCTION....MY HEAD STARTED TO HURT!
Preface: Original poster was "stoney98", he/she started this thread, to help us all. I (FXTerrific) have since updated this OP, to include additional setups, as well as update some info in general, based on findings from members, since the original post date.

**If you are unclear on how to install, ask for help or find a professional. If you aren't sure what you are doing, don't do it!**

Options for lowering your SH (09-13) forester. These will work on both XT and non XT models, with the exact same outcomes. All spring rates are in "LB/IN" spec, unless otherwise noted.
So, in no particular order:

*Pedders Springs on OEM struts

Drop: 1.6". Rates: ?.
@Galager has some nice info on these.
Galager's install thread


*Swift Springs on OEM struts
- First version - Drop: 0.8". rates: ?.
"jesusv":
@jkoppee (old car): - stock springs vs swifts springs


- Second (current) version (#4F908) - Drop: 1.6". rates: 213F/202R.
???? who's got pics?


-------------------------------------------------------------------------------------

*Impreza/wrx strut/spring complete "takeoff" assembly options. About a 3" drop, with some variation, based on model year chosen.
These are all bolt-in ready. No fabrication or spring removal necessary. These are going to be the easiest to install.

+08-14 impreza (non wrx) model = they'll all work, not sure on rates, but they'll be soft. maybe too soft. i think theyre the same as 08 wrx - 151F/136R.
+08 wrx model = 151F/136R.
+09-14 wrx model = 217F/194R.
***08-10 wrx model struts have a shorter body length then 11-14 model ones, by about 0.5". this will effect things like tire clearance vs the lower spring seat...as well as ride height.***

"Mattesonb" - wrx (not sure on year, or if any strut spacers used)


"2010subaruforesterXS" - wrx (not sure on year, or if any strut spacers used)


--------------------------------------------------------------------------------------

*sti strut/spring complete "takeoff" assembly options. About a 3" drop, with some variation, based on model year chosen.
Fabrication on the front struts is necessary (but the rears bolt on directly). ....see this thread for more info as to how/why: Raptr's install thread: 08 STi Struts on 09 FXT

+08-10 sti model = 217F/194R.
+11-14 sti model = 250F/297R.
+08-14 sti "pinks" = 280F/224R.
+ sti SE springs = 250F/250R.
@RAPTR - 08 sti stuff:




With 1" strut spacers , all four corners.

@GTEASER :


-------------------------------------------------------------------------------------

2010+ Legacy takeoffs
Drop: ~2", but the rear sags
*** 2013+ are a little better, and preferred. The rear struts are shorter, so a 1" strut spacer should be considered. Needs WRX/STI/Forester tophats....Legacy ones won't work.

Shown w/ 1" spacer in rear:


-------------------------------------------------------------------------------------

Aftermarket spring/strut options:
GTWORX WRX Bilstein/RCE setup @Nollie :

...Same, but now with RCE yellows:
WRX Suspension Swap Writeup

- Other (WRX/STI) spring options that come to mind (make sure you pair these with the appropriate strut!!!):
RCE black
RCE yellows
Epic Engineering
Mann Engineering
Whiteline
Eibach
King lift springs wrx 1.25" and are about 25-30% stiffer than stock (rates not advertized)
...then all the others like Tanabe, Megan, etc etc.

It would be nice to gather some qualitative data on these setups. I am on 08 STI struts/spring (with 22mm RSB and 25MM FSB) and I need to change it as I hate how rough the ride is. I loved my KYB AGX w/ STi Pink springs on my WRX.

"rough" as in jarring or as in soft/bouncing down the road?

Please add Galager's set up with the Pedders Springs in the same format in the first post. That is a 40mm drop.

I wish I could but a little steep for prices. How about you "lend" me some money and you just keep your RSR setup... haha

A couple for sure. First to jump in my head are Shansen, lourok, dmv-ck, excipient and some Aussie members...not to leave anybody out, haha. At least some different brand coils in that group iirc.

2010+ legacy takeoffs fit too with forester/wrx tophats. 2013+ has a better/higher dampening rate. The rear sags so this is with a 1" spacer. I have since changed the front springs to 10+ lgt swift springs. Other pics are in my journal.



With lgt swifts
