Lucien, Might I suggest getting in on the Group Buy on Magnecor KV85 Ignition leads currently going on in the Vendor Section. Won't make the car handle like a 325I but sure looks nice every time you pop the hood and you'll most likely never buy another set of wires for the OutBack!
On the Spring/Strut issue you might want to look into Dale Teagues Wagon specific springs from WhiteLine. Check postings this board last 30 days to catch up. Don't know why the OutBack would differ any from our GT's as far as fitment. And if it's handling you're after that runs opposite of "Ground Clearance" issue. Just my $.02!
