how did you manage to do that? did you have them replaced under warranty until you find something better?

Still pretty confident front is the same between new legacy and impreza. Tops, mounting, control arms, spindle, are all identical. I've been under a few of each lately. As for the rears, they're really, really, similar. The lower mount is a bit different, but the lenght and motion ratio look very close. I'm thinking all it takes is to loosen the top nut to rotate the shaft 90* and swap out the lower bushing (or make a sleeve). The legacy uses a bigger bolt because it hangs off the side of the link where on the impreza it's held in a stamped steel u-section.

would be nice if the front strut housings were identical- more sources for donors- also the 09 WRX w/ the firmer damping might make for a nice upgrade for the Leggy's.

I'm still a little fuzzy on the upper rear, swapping the lower shock bushing part makes sense (different size bolts)- I'm not visualizing the upper rear- is there a bearing in the upper spring perch/top? A threaded shaft at the top of the strut? Is that what the one poster drilled out?

thanks

it's just a smaller top hat with two mounting bolts instead of three. So yeah there's a threaded shaft and top nut.

As posted above, just a two bolt top hat, the bolt pattern and center bore is different between the 05+ Legacy and 08+ Impreza.

The front strut housing is similar, however the spring perch and hub bolt pattern is not.

I tried 06 wrx strut housings, they sat too high, and lots of +ve camber

^ does the rear top have a bearing center section like the front (and "old" rear)? Is that what you drilled out?

thanks

Its not really a bearing like the front top mount.

Imagine a smaller pre 08 Impreza top hat, smaller, two bolts only, with similar components, rubber insulator with a fixed center. The center bore was too small for the Legacy's larger bore strut, so I had to enlarge it a little.

OK- that's makes sense then, I was thinking it would be a little risky drilling out a bearing center

thanks

update on the Koni's

Koni Holland evidently has delayed the release of the 08/09 Koni damper, time frame is unknown- it could be quite some time .

Good news is Lee Grimes from Koni NA is very excited about developing a good damper for us I mailed off a front strut and rear shock for test fitting today. He's pretty confident they will be able to come up w/ suitable dampers.

Should be hear something back after the 1st of the year.

WRX- AFAIK the STi still utilizes a inverted strut up front so an insert is a lot tougher (if this isn't the case someone please post up )

they got to look at the rear shocks today- as expected the Koni LGT shock utilizes a different lower bushing, as expected the threaded pin is a different diameter on the Koni LGT vs oe WRX- the shock body is shorter on the Koni LGT shock by ~ 1" and the LGT shock has ~ 1.5" less of overall stroke

they're going to look at the front strut next week

Figured that, it does sit lower in the rear. No major handling issues though, and it is a night and day improvement over stock.

update from Koni today- they successfully installed the front insert into my donor strut- fitment was very good - the only suggestion they had would be to cut a little less on the WRX strut vs the LGT one

sooooooooo here's where we sit. at the moment we have a viable option w/ the LGT insert/shock- as aross mentioned it is NOT going to be plug and play so this won't be marketed by Koni as a WRX setup for now

if you want to use this setup you will have to swap in your WRX shock bushings, you will also have to slightly drill out the rear top- the fronts are a plug/play (well except that part about cutting up your strut )

now that Koni knows they have an off the shelf front insert that works, they only need to work on the rears- they believe that it will be relatively easy to get the rears into spec- they will develop the correct lower bushing and then probably taper down the shock pin so it fits w/o drilling

that's probably going to be awhile before that gets done, sorry I don't have an estimate

there is even some chance that Holland comes up w/ a full strut front replacement, that would be down the road (if it happens at all)

so we do have an option that will work, with some work

I'm looking for folks with 09 WRX's that have installed the Koni inserts and would like to hear what they think of the setup ride wise and installation.
