Well, they are adjustables, and I knew they wouldn't be "ideal" but, well, the parts were there and the welder was there and even if you fall on your face you have still moved forward... (It was $60 for a pair of Koni Yellows for a '02-03 WRX. Bought them for a quick flip, turns out nobody wants Konis because you have to *GASP* cut the tops of the strut housings off!)

They work fine except they have a tiny bit too much initial damping, they're a bit stiff over light bumps. Certainly a hell of a lot better than the worn out KYBs I had before. Stock WRX/STI rear spring rates are higher than the 175lb-in i am running (225, I think?) so I didn't think that'd be an issue.

Ok works fine. But I do not think the stock subie springs are that high. I Supply 225 rear for my stuff and thats an up-rating.. Everything Subie guys say is suspect--for that matter everything most people say about things is usually hearsay......

Personally I avoid Konis because all the way back to mid-60s to early 90s everything they make for bike or cars seem to have way excessive high shaft speed compression damping---to the point that on square edge bumps they seem to hydraulically lock.. I believe they have this problem because a) there hasn't been a bump in all of Holland since 1961 and b) they know 90% of people they sell shocks to aren't changing springs, and that way sudden stiffness means the cars "feel flat" if somebody does sudden jerky wheel movements...that's the "sporty" feel, and makes conesquishers and 'lane changers" feel all Mario Andretti-ish..
Amazingly consistent harshness from the old "D" Specials to yellow monotube stuff....so must be an in-house deal..

But what the hell do I know?

No, that sounds about right. The solution is to just drive faster.

You should have seen some of the suspension setups that people had at Nationals. Some cars I don't think the suspension moved more than an inch all weekend.

Epilogue: Started actually driving the car after my friend dragegd it home for me and I parked it. Hoo-boy, something's effed up in the front end. R/F upright is tweaked so hard that the tire is crammed into the strut.

So, I think maybe it is time for something a little more beefy. I have spare uprights but I also have had a crazy idea for a while that involves hackifying an old W-body GM front strut housing to meet my own mad ends...

Back in '04, '05 we used Tokiko Illumina struts for a Camaro as cheap, build your own adjustable rally struts, to fit my friends Corolla and Golf rally cars. Not the greatest, but for the money, it worked great.
