Swapped the WRX Wagon Swifts & WRX GR2 combo for the Forester Swifts and Forester GR2 unit last night.
The WRX setup was an awesome combination of sporty handling and comfort but my driving now requires a bit more ground clearance and if one finds something that works why jump from the wagon right? So the other obvious combo would be Forester Swifts and Forester GR2s. The WRX combo gave a nice 3.5"/3" drop front/rear. The Forester bits dropped 1.5" front and .5" for the rear.
I got the springs on a group buy from Gary @ Mann-Engineering. The struts were bought off ebay. I use the 334342, 334343, 334344, 334344 KYB part numbers that were designated for the 2003 Forester. The 334370 and 334371 are part numbers for the 2004 to 2008 Forester. If you want to replace your struts with aftermarkets, save the $60 for your gas tank and just buy 334342/334343 fronts struts.
Notice length difference of the WRX and Forester bits...
Installation was along these lines...
JDM Forester STi pink springs for SG (03+) - ScoobyMods
I learned something out of this. Save your OEM parts because you never know when you will need it. I ran F-STi JDM springs with OEM struts but sold that takeoff. Then I got my WRX combo and had to build from parts I found on NASIOC and local wrecking yards. I have a buyer lined up for the WRX combo so I couldn't separate the tophats, but could only use the fronts though, from the unit. New tophats, bumps stops, strut covers, etc can cost some $$$ new or used. Well at least the WRX combo will go into another Forester.
I was able to score a pair of 06 STi rear tophats cheap and sea-scooby donated to me his buddy Jeff's 2001 Forester takeoffs. I was able to use everything from the 2001 Forester except the rear tophats. The rear strut covers were not a perfect match to the 04+ tapered tophats but I manage to get it to wrap around the bottom rim of the rear tophat. I was thrilled!
