Default 2004 Wagon Springs - Real Options

After much searching and reading, I thought it best to start a sort of consolidated thread.

As of right now, there seems to be very little solid information on springs for 2004 wagons.

Correct me if I am wrong:

-Prodrive never makes wagons specific springs.

-Eibach makes wagons specific springs, but not yet for 2004. And know one knows if they ever will.

-Whiteline suposedly makes 2004 springs, but the PDM website has a "NA" for the rear springs.

-Tein is not making a wagon specific spring for 2004.

Am I missing anything?

Basically, as far as I can tell, no manufacturer specifically recommends springs for the 2004 WRX wagon. In about three weeks I will have had my car for a year. Frustrating. I realize that people get good results using non-wagon specific springs, but it bothers me that the manufacturers are not specifically recommending them.

Not true, they don't make wagon specific springs, but they say sedan springs will work fine on a wagon, and they're right.

The wagon is slightly heavier in the rear than a sedan, and it's stock springs are slightly stiffer in the rear to compensate. In the world of even stiffer, lower springs, the front to rear stiffness ratios aftermarket companies are engineering into their product work fine with a wagon. Putting sedan springs on a wagon might result in a slightly different balance, but it's not a "problem."

Also Whiteline's website gives rear part numbers for 04 specific Control and Flatout springs - sedan, not wagon. (Actually the rear suspension design change came in 03 for Japan and Australia.)

You can find a lot about spring rates here: http://www.northursalia.com/t...ng/spring.html

For the 2--4 STi, they lower the car -1 inch up front, -.4 in the rear, and feature spring rates of 229 lbs front, 196 lbs rear. For 2004 wagons, lowers the car -1.5 inches up front, -.4 inches in the rear, and has spring rates of 229 lbs up front, 196 lbs rear.

Thanks for the late night replies.

Hopefully this thread will pop up in searches. I did something like 15 searches last night.

Tein markets the same spring for WRX sedan, wagon, AND the STi - check the part numbers. The drop is slightly different on each because, well, it's a different chassis. Those spring rates are for the STi. I wouldn't use them with stock WRX struts.

The info on Tein's website is a bit suspect. For the 04 wagon it lists the same part number as WRX sedan and STi, but it lists a different spring rate. It is, however, the same spring rate as the 02-03 springs. Huh?

Hmmm. I really wish a major parts maker liker Eibach or Prodrive would come out with a spring set and said "This is the one for a 2004 WRX wagon with stock struts." I may just go with the Eibachs's for '04.

(Edit, subbed Eibach's for Tein's).

Eibach made a wagon spring for 02-03, but apparently it wasn't a big seller - no rush on an 04 version. I've heard of plenty of wagon folks happy with the Prodrives. They work fine on a wagon.

The prodrive 04 springs are supposed to be for both sedan and wagon from what I have read. They were supposed to have come out awhile ago, but apparently they are "on the boat". Myles at RaceCompEngineering told me that they are supposed to be hear by May 15th. I am looking forward to hopefully trying them. I am in the same boat as you in having trouble finding a spring for an 04 wagon. I am not sure about the Tein's. I read a lot of posts from people saying that they would never put them because the drops are too much.

Now the waiting begins.

Please PM me or post a review in this thread when (if?) you get the Prodrives.

Thanks,

I did some research, and I'm running sedan tein s tech with kyb agx's.. The only reason I went with the tein s tech

a. we have limited options
b. the springrate difference was so minor, (10 ft/lbs) it wouldn't really matter
c. the wagon is only 80 lbs heavier, so its like driving around with two spare tires in your trunk. Which on the flip side can be good because you have more weight pushing down on the tires.

Cant you just switch to 02/03 rear strut tops? That would open some options...

I guess I am just getting overwrought. I was under the impression that the struts were different beyond the tops. But the reality is that changing the unsprung weight with new wheels and tires kind of throws the whole "designed to work with the stock suspension" out the window anyway, and I plan to get 17" wheels when the stock tires wear out.

Heck, springs are not that great of a performance mod anyway.

A few board members have heaped praise on the '04 suspension. I'm kind of on the fence as to whether springs are really worth it for my '04 wagon. I don't know if there is enough of a performance increase, and I don't want to lose ground clearance just for looks. I would definitely consider '02/'03 strut tops and a set of Prodrive springs if I was going to do it.

The 04s have a revised rear spring/strut top design, and the struts have different multi-phase valving. A stock 04 is supposed to be a better ride than a stock 02-03. But, it's still a fairly soft setup.

Add 02-03 rear strut tops and you can use the old design springs no problem, and the new struts will still work fine with Prodrive springs.

I just installed 04 pinks with Koni's on my 04 wagon and I am pleased. The ride is a little bouncy at high speed but I am still working on dialing in the struts. I have a novice autox school this weekend so I will find out more on Sunday. Tucker

Mark Avery is spot on about the suspension revisions on the '04 WRXes. But the '04 WRX wagon is, to this butt, significantly firmer than an '02-'03 WRX wagon. I test-flogged one, and that car is a sedan swaybar and rear STi pink links package away from being a superlative handler.

Springs are always a compromise, because a) they will, however incrementally, shorten the life of the stock struts and b) they take the stock struts out of the preferred range of travel, which explains why ride quality often deteriorates when springs are added to a car.

I have the SPT wagon suspension kit on my '02 wagon, and after driving the '04, then getting back into my car, my car wasn't a whole lot firmer. Were it my '04 wagon, IMHO, instead of looking at springs, I would:

1. get a sedan swaybar
2. get some of the pink STi lateral/trailing links at the rear
3. go for that 17" package, if you still think you need it after feeling how well the car works with the above two.
4. drive happy

I wonder whether there will be a SPT wagon kit for MY04, like the ones for MY02-03. Anyone knows?

Not likely- sadly FHI isn't making the GGB anymore. That is what the SPT it was based on- just oem STI wagon bits. No more STi wagon, not likely a SPT 04 wagon specific kit.

I just swapped from the sedan to the wagon and ran the STi RA setup on my sedan- I loved it. I'm going w/ the 02/03 STi wagon springs/struts, combined w/ the Grp N tops (02/03 rears). If the "normal" STi spring rates aren't quite what I'm looking for, I'll pickup a set of RA springs. Sedan springs will work fine w/ the wagon- even STi's aftermarket "pinks" list one part # for both wagon/sedan. The spring rates oem are the same in the front w/ a very slight increase in the rear for the wagon (very slight).

As mentioned in another thread, I'm going w/ takeoff 04 USDM STi springs/struts and mounts on my 02 WRX wagon. I'll be adding camber bolts in the rear and group-N topmounts in the front. I have been forewarned that I may not get adequate camber in the front--in which case I will swap in camber plates.

Let's all camp out in front of H&R or Prodrive headquarters and demand them to release '04 springs (angry village mob style).

I'm going to take back my comments on sedan springs working fine- they may and they may not.

v7 STi pinks- not wagon or sedan specific. Advertised drop 20mm f/r, w/ sedans this is prety close to what they get. What I'm finding out is that w/ the wagon (and these are wagon specific ST struts mind you) they're seeing a 20mm drop front, but in the neighborhood of 48mm drop in the rear!

My guess is there is a significant differnce in free length between the sedan and wagon rear springs- this is supported by GGB and GDB using different springs (but the same rates).

I'd like to hear from folks trying different non wagon specific springs w/ ride heights front/rear (measurements should be taken from center of wheel -straight up to the wheel arch).

Not good news when I found this out about the v7 pinks
