What's the verdict?... Rear sway bar compatability

Alright... I have a '93 FWD Impreza Wagon that came with no rear sway bar stock. I'll be adding on in the spring, along with a rear disc swap. I'm using 92 FWD Legacy sedan trailing arms, lateral links, knuckles, etc. The trailing arms have the metal drop links instead of the c-shaped endlinks, like so...

Image

I'm just wondering if I can use a rear sway bar meant for use with the c-shaped endlinks with this setup, or if I need to get one made for use with the droplinks.


Also, I found this picture somewhere...

Image

They look like aftermarket poly bushes (maybe Whiteline?). But I haven't been able to find them anywhere. Any insight on these?

keep the same rear sway bar and get a complete set of the sti arms and call it a day, 10million times better. just my .02

I would, but they are too expensive. I already have the Legacy rear suspension/ brake stuff, so that's what I'm using.

those links aren't a direct swap for FWD cars anyway. I've heard the the 90-91 Whiteline swaybars come with those endlinks.

Otherwise there are some people who have rigged up stiffer endlinks with urethane bushings they got from energy or something.

What do you mean they aren't a direct swap? How so?

the rear inner bushings and possibly some others are different.

Oh, that's all? I'm planning on replacing every single bushing, nut and bolt, on the rear of the car anyway, so I'll just order some FWD Impreza bushings.

So anyway, back to the original question.... :)

Do you know if, say, a GD WRX bar would be compatible with those endlinks?

Nico, what is that blue bar coming down between. Not see that particular bracing before. What's it all about?...

Those "pin in a box" style connectors are crap! I think its worth the effort to replace the rear most control arm to get the newer style of attachment. Thats what I did

I'd assume that blue brace is another one of those questionably effective yet expensive cusco braces that just adds weight to an already stiff part of the car. The trunk brace especially cracks me up.

I've heard good things about the fender braces though so I'm not going to discount everything entirely.


Anyhoo, as mentioned in the "installing a rear swaybar" stickied thread, the only swaybars that will fit are those from a 90-99 Legacy because of the spare tire well. I was going to find out how far exactly the bump needed to be "moved" out of the way awhile back but the shop I was at didn't have any 20mm wrx swaybars. Additionally the STi bars are wider and will not work unless you swap to the lateral links like the ones Nico has.

If you could find parts from a 93+ you could use the more common C-link setup and be better off. I've heard yes and no about mixing the two types of swaybars.

Yes, was wondering about those trunk braces. Check out this set, pretty elaborate...

Yes, i'd go to a WY and pull those stock lateral links off a junker. You may need a cutting tool to get them off tho. Those bolts tend to seize up...

Were talking about an Impreza here, not a Legacy. GD WRX bars fit the 93-01 Impreza with no problems. I'm aware of the STi bars being wider too, and bolting to the outside of the endlinks.

I guess I'll be the guinea pig with this combination. I'm too broke to be buying more parts. And I already have the lateral links and brand new endlinks, so I'll just use those.

oh right I just kind of didn't notice that.

the blue thing in the middle does work only on hard hard hard hard driving like what i do lol. i forget what there called.

but it makes the arms not twist and it locks the rear sub frame in place like the other product from whiteline so its a two in one thing.

Thanks Nico, Interesting if you find a link to where you go those please post or pm

Those adjustable swaybar links are whitelines BTW. I sold a set to Devan/Livestrong. Ping him and see what he thinks of them. I got them from PDM Racing in Vancouver. They came with my Legacy specific rear sway bar. But my car's a 93 and so had the arms that use the solid C links.

Go on PDM's site for nice fitament chart.

Good luck!

So, you were able to use the sway bar meant for the old style endlinks with the regular c-shaped endlinks?

The old style endlinks have more to do with the lateral link style than the sway bar. So, yes, the "normal" c-links and the dangly adjustable links (old style) both work with the Legacy adjustable bar (it's just a hole)...and in my case the danglies CAME with the the Legacy bar. Tjey might have been shipped by accident in the box or something, PDM is very confused about their Subaru stuff and I wouldn't recommend them as a help vendor...except for that table.

Overall it is all very confusing dealing with Whiteline stuff b/c model years are slightly off but between the table at PDM racing and the Whiteline USA site I was able to figure it out.

Ok, I been buying parts, doing research, and piecing things together... here's what I've found out...


The Whiteline adjustable bars are supposed to come with the Whiteline endlinks and poly bushings. They are also sold seperatley too... Whiteline P/N KLS090B.


Here's my setup. Comments are criticism welcome. :)

Image

Image


All 4 bushings on each endlink are Whiteline P/N W0007. I used 8 all together. The lateral link -> endlink busjings are a great fit. Slightly shorter than OEM, but I don't think it will be a problem.

Whiteline W0007 vs. OEM 20471AA000...
Image

Image


Now for the sway bar -> endlink bushings, I needed to trim the W0007's down to 11mm thick. Pretty easy with a 32TPI hacksaw. (I didn't buy any OEM bushings to compare to, but for reference, the OEM part is 20461AA002.)

Image


OEM endlinks are 20480AA002. The washers that go on the end of them (not pictured) are 20267AA040. The nuts that go on the end are 902350001.

For the bolt that goes through the endlink, I used a stainless 10mm x 45mm bolt and ny-loc nut with a flat washer and lock washer on each end.

Image


The holes in the endlink are only 8mm, so you'll need to drill them out to 10. (I recommend a step bit for this... A regular black oxide bit of the right size got me nowhere. The reason for using a 10mm bolt is because the hole in a 17mm WRX swaybar is 10mm.

Looks great. Thanks a lot for the follow up and pictures.

looks very good. let us know how you like it, when i did mine along time ago i just used brand new factory stuff, but this set up you got is going to be nice and tight.

I got those links for "free" with my bar ordered from PDM racing. But I've got the swapped out lateral arms (the car came like that) so I have the Whiteline solid rear "C" end links I sold the set above to Devan (Armstrong) and he's been running them for a while...

Good luck! ADM/OEM stuff rules!!!

Note: keep wax on the swaybar b/c it can rust in a few years.

Cheers,
AW

No problem :)

And hopefully the P/N's for all the OEM stuff will help someone out in the future, because I found it was a p.i.t.a. to find them! I was e-mailing Jamie at SubaruGenuineParts.com for about a week trying to find the right parts. She was a huge help though.

I hope it will be nice and tight. I can't wait for warmer weather to install all of it. Too cold right now.

Thanks for the tip on the waxing.

Pardon my n00bness, but what's ADM?
