Default 08 STi stock springs on 09 WRX - pics

Mods, feel free to combine this with any other threads on this subject. I can't find the one I was thinking about!

Anyhow, got some lightly-used 08 STI stock springs from Dan at MachV (thanks for the great deal Dan!). I only installed the fronts, since other posts have shown that the rears on the 08 STi and 09 WRX are both the same height and the same rate, so why bother.

After and hour of easy work (damn these cars are easy to work on) they are on, so here are some pics and measurements:

before:
FR ground to fender: 27"
FR hub center to fender: 15 3/8"
FL ground to fender: 27 1/8"
FL hub center to fender: 15 1/2"

after (driven aroud for 20 mins)
FR ground to fender: 26 1/2"
FR hub center to fender: 14 7/8"
FL ground to fender: 26 5/8"
FL hub center to fender: 15"

So as we can see, it was an exact 1/2" drop (the springs off the car are also about 1/2" shorter than te stock 09s). Also set the max negative camber available using the stock eccentric bolts (which is not much). Alignment tomorrow.

Ride and handling are unchanged so far as I can tell after 20 minutes in the windy forest roads nearby. Intentionally tried to bottom them out but only did it once on a heavy off-camber downhill 90* turn, and it was light. There were a few big dips and speedbumps too and didn't have any bottoming issues.

All in all a good "looks" mod that slightly reduces center of gravity and doesn't negatively affect ride or suspension performance to any noticeable degree IMO.

full-side shots (on a very slight slope)

nice- 10-12mm drop, still well within factory spec even

lmk how much camber you can eek out up front (*hint- make sure they fully loosen that bottom strut bolt before they start messing w/ the eccentric bolt-alignment techs are notorious for not doing that)- someone emailed me they got -1.4 w/ theirs- I thought that was pretty decent

I have an old longacre camber gauge that was reading somewhere in the neighborhood of -0.9 to -1.1 with the eccentric bolts set to "max" camber setting (the side nick mark vertical to the strut and the "11" pointed toward the strut, about 90* from the stock setting). By the arrangement of the suspension, I suspect actual max camber is with the bolt about 10* off the vertical/horizontal mark axis, but didn't want to play around too much with it since I have only marginally effective measuring equipment here!

I did in in the driveway though, so can't say exactly.

went by a local tire place that has free alignment check this afternoon, but they had 2 cars ahead of me and I didn't feel like waiting. Will try again later in the week.
