GR2 the same on 91 and 92-94?

legacy92ej22t · Post by **legacy92ej22t** » Wed Jan 12, 2005 4:59 am

I know that the rear spring is different on the 91 but is the actual strut itself different on the 91? Can a GR2 rear strut off a 91 be made to work on a 92-94? TIA.

yes, but the rear perch is .5" higher on the 91

So putting 91 GR2s on a 92-94 would have a lowering effect?
I need to hit your suspension compendium, scott.

no, just the opposite.

As long as they're from an AWD model, they'll physically fit. However like mentioned there will be some alterations in ride height. Here's my thread with the info from KYB directly

I thought I remembered reading somewhere in that thread that putting 90-91 GR2s on a 92-94 would kinda lower it, because the perches/seats/whatever were lower.. guess I was wrong. Perhaps it was vice-versa..
Thanks!

You might have been thinking about me.

Sticking with 92-94 front struts, and 91 rears for tire clearence.

Well, I remember reading about the differences in the spring perches, seats, and whatnot, and since my 91 had the nose-to-the-sky thing going on after I put the GR2s on, I thought it would lower the 92, instead, due to those differences. ..but you all know me and my skewed logic.

legacy92ej22t · Post by **legacy92ej22t** » Thu Jan 13, 2005 4:07 am

Ok thanks, so physically they'll fit.

Next question though is can I use 92+ springs though or do I have to use tapered? Can I change the seat or perch or whatever to be able to use the 92+ springs?

I'll recover some stuff that was said in an effort to be complete.

90-91 struts will bolt up to a 92-94 car with no modification. The nose will be 1.25 inches too high, and the butt will be .5 inches too low. This is because the spring seats (the part of the strut that holds the spring) is welded into a different location. The fix is to use 90-91 springs as well, but they are tapered in the rear, requiring a different spring perch (the top piece). I'm pretty sure the front spring perches need to be changed too, at least i had to when i went from early legacy to GC springs. In all, it's more cost effective and easier on the noggin to buy the right struts for your car, unless you have a low miles 90-91 and can forsee changing the struts again.

1.25" in the front? I thought it was .75". Well crap. I don't want the front end to end up being higher then the rear.

Right now my rear end is higher then the front, giving my car almost a raked look. I was thinking that the 91's might actually level everything out but now I'm not so sure.

scottzg · Post by **scottzg** » Thu Jan 13, 2005 10:02 pm

1.25 is the front. .5 is the rear. Sounds like a winner

BAC5.2 · Post by **BAC5.2** » Thu Jan 13, 2005 11:10 pm

Matt - If you are talking about the suspension I am thinking of, the whole setup should swap right over from strut, spring, and top perch to top hat.

All you need, are the struts, the springs, and the upper perches.

Your car will sit exactly like the car we are thinking about does now. As long as you use both the front and rear. Since your changing the whole package over.

You should be fine

legacy92ej22t · Post by **legacy92ej22t** » Thu Jan 13, 2005 11:33 pm

Do you really think so?

Oh, and I'm sure we're thinking of the same car.

BAC5.2 · Post by **BAC5.2** » Fri Jan 14, 2005 1:08 am

Well, if you swap the whole strut assembly along with the springs, then yea, it'll be the same.

The strut mount points are the same on the knuckles, and the strut towers have the same dimensions. The facelift was cosmetic, not geometrically different.

The springs on the car are likely a little shorter than 92-94 springs. Either way, I think it'll look fine on your car.

Now, if you did use JUST the struts, and your stock springs, it would raise the front and lower the rear a little bit. But you aren't using the stock springs, are you?

I've pulled the suspension in a few Subaru's, so I've got the setup pretty well down, and I can give advice on installing them too.

Keep in mind, the car in question rode VERY harshly.

You should tow Subarina down with you

let's try this on for size:

I'm using a '90 Legacy as a parts car for a 5-lug swap and EJ22 transplant into my 86 GL10 wagon.
The rear has GR2s to fit an 88 (GL body'ed) RX (with 3 adjustments possible) and stock springs..
the front will have '90 spindles, etc and RX springs (157lbs/''). I'm putting a lift kit on this car and I want whatever front GR2s will sit highest. I see some ambiguity regarding whether the '90 struts or the '92-'94 struts sit higher? can we figure out what my car will like best? I am planning for a good "compromise" suspension. obviously if i'm lifting it, it's not going to be ideal for rally driving, but i'd like it to be between hardcore offroad and hardcore track handling.
???? and thanks
Andy

Im not sure how much lift 5 lug struts are gonna give you, but all BC/BF front struts are the same if Im not mistaken. its just the rears you have to worry about.
BTW post pics of that GL10, sounds cool. I'd love a EA81 hatch with an EJ drivetrain...

92-94 KYB's will give you 1/2" more height.

baccaruda · Post by **baccaruda** » Fri Apr 01, 2005 9:33 am

thanks. i'm now trying to figure out what front springs I want, as the GL/RX front springs I have now are too narrow to safely use on the Legacy struts. Is there any info about legacy spring rates?
My RX springs are 130mm/5.12" diameter, and the coefficient is 27.5 N/mm or 2.8 kg/mm or 157 lbs/inch... I'd like something close to that or a little "more"..

thanks for your interest. here's a couple pics:

)

wait, i just found this http://bbs.legacycentral.org/viewtopic.php?t=2153
so I want 2.5RS or WRX springs, and I might consider a spacer to negate any lowering effect.
since it says the spring seats are different, could I compensate for that with a spacer? or do i need to see if '90 legacy spindles will accept GR2s for a WRX or 2.5RS?

scottzg · Post by **scottzg** » Fri Apr 01, 2005 9:56 am

Glad you found the compendium, i was about to make fun of you.

If you want to lift the front, you want 90-91 springs and 92-94/gc struts. All new gen struts will physically fit, but the matching springs are not all the same diameter at the ends.

As the ea car will have a lighter front end to begin with (i think) you may not need that, or the fenderline could be different, or something, who knows. In short, bolt something up so you can establish a baseline, then adapt from there.

Please note that what i labelled a 'perch' is what is different, rather than the 'seat.' This may be incorrect labelling, but since i wrote it, im gonna stick with my phrasing.

The spring perch is what holds the spring in compression, im not sure how you're gonna replace that with a spacer.

As far as replacing the spring with something a little "more" the main thing you'll be changing by altering one end is the handling character more than the ride quality/handling prowess ratio. I'm prolly preachin to the choir though.

I recognize poogot rims!
