Happy Easter! Is there a 1996-1999 Outback wagon in that same yard? If so, it's rear sway is bigger.* And the bar won't be physically wider like the 02 wrx sedan bar will be.

*The very, very earliest of the 02 wrx sedan's got big phat sways. They did away with them because Americans were wrapping their cars around trees. The 02-07 WRX Wagon got the 20mm bars, and its width is the same as yours. That's what I use on my cars.

Come on, Mike. Just when I thought I understood something. I believe you because you know everything, but here is the thread I found my info at: Stock FSB and RSB sizes .

So what I am looking for? lol. I don't want one from an 02 sedan? I want one from a Wagon? And that will fit better? Or from an 96-99 Outback Wagon (and when I search car-part, is that considered a Legacy or an Impreza)? And when I get to rounding every bolt when I take the old one off, should I buy all the hardware from whatever car I go with with the sway bar or can I use the existing stuff? I appreciate it!

Haha. The 02-07 WRX sedan (and all GDs, for that matter), had wider track suspension. You can certainly bolt a wider sway to your car, it fits on the outsides of the c-links now. The downside (from what a very smart suspension guru told me) is that under compression, the wider track sway bar on a narrow track car loses it's advantage (of grip? I'm not smart enough to ask the right questions re suspension).

He said to use all narrow track or all wide track parts (with preference towards the latter for racing) on our cars.

That link is partially wrong. Look down further to see corrections. You do want a sway bar from a WRX GG Wagon since that has the narrow track like our cars. And those are 20mm. In absence of that, a 1996-1999 Outback wagon has an 18mm RSB. Your link says the the RS RSB was 13mm? My RS one was tiiiiny. So I can believe that. 18mm is good enough to cause oversteer. It's what's still on my old OBS, and made for lively handling. ;)

My hero. I've spent enough money and made enough mistakes on this project already. Well worth it, of course. But it's nice not to make the mistake in the first place. That's my preference, anyway, especially considering I am bound to make more mistakes later.

I'm very glad for you and others on this forum. There's so much to learn, and I'd be so incredibly lost without this place.

Thank you for the kind words but I definitely don't know a ton about Imprezas. I've been messing with The GC's daddy for much longer. The almighty BC! Luckily the BC and GC (and etc) are pretty similar. ;)

Just read through your journal--seems like a fun project and you're making good progress.

You can actually order a 20mm factory GC8 rear swaybar from the dealers here in the states. From what I've been told, this bar and the stock front RS bar are a perfect setup for spirited driving (not tracking). Look into this forum post here about the P11L springs created by 2pot. Lots of fantastic information in that thread about suspension setups for these cars--a must read.

You are 6 hours too late to save me $25 on brackets and bushings and 36 hours late on saving me $30 on an 18mm sway bar from a yard lol. But I'm dumb enough to keep going.

If the answer to this question is in the forum post you listed, sorry for asking in the first place. I imagine if it is a factory 20mm GC RSB that it should match the track of my car? (I hope that sentence makes sense). It's amazing how in over my head I am all the time; I know that's how you learn (sort of), but just when I think I have something figured out or think I made the best move, something else pops up.

I appreciate the info.

In my opinion, no such thing as a bad question. That forum post is quite lengthy so I understand it can be a bit cumbersome to get through it all. To answer your question - yes, this bar matches the GC track width. It is a factory GC bar that came equipped on (I believe, not as well versed on the markets other than USDM) V3-V6 WRX's of the time. However, it is available in the US parts supply chain (JDM clear taillights are also like this for example, not offered here on any car but stocked here).

An easy way to tell if a part number is for a GC is if it has "FA" in the lettering. FE is GD chassic, FC is Forester, etc. Now, this is just a rule of thumb as some parts are shared between models, had revisions, etc.---but can serve as a good quick check. Just a quick fun fact for you.

Back to bars- still a worthy upgrade. Doesn't hurt to save some money going used. I am not sure of the differences exactly (heard both ways) of the GD vs GC bars, but it appears mike-tracy has covered that well for you. I would recommend getting new upgraded swaybar brackets of the later STI's (see: 20540FE200, 20540FE210) - much more stout than the earlier ones. Polyurethane swaybar bushings could also be good upgrade. I am the type of individual where, if I am in there I do everything.

Do you have any other suspension plans? This is an area I believe it is best to plan out and get everything at once versus bit by bit - but again, personal preference. Perhaps others here can provide insight into your plans.

Thank you! After your post, I did some research and found those part numbers (and others) on Demon's journal and put them all in my cart. I'll probably order them up this week. A bunch of really good info, so again, thank you. I know I know basically nothing, and I'm still impressed with how much I don't know (and please don't take that as me being hard on myself...just stating the facts, knowing that I just need to keep working at it!).

I want to upgrade the suspension, but everything about it is so daunting, so I have been dragging my feet. I pulled the trigger on the sway bar because it seemed straight forward enough. I bought aluminum C-links, but I couldn't figure out what I needed for poly bushings for that bar (or any bar lol), so I figured I would give up on that one for now. For suspension, I haven't really read anything as of this point because most of it is dense and mostly over my head. The goal would be to get something that would improve handling without compromising daily driving potential. I can handle a rough ride, but I'm not looking to track the thing or anything intense like that. Plus, once I get the point of even ordering the suspension, installing it will most likely be an adventure, as is every project I undertake that requires even a smidge of mechanical skill. I haven't even bothered asking here yet because I figured when summer came around I would have some time to do some reading and researching so I actually knew what questions to ask in the first place. Or, more likely, after not understanding after reading and researching, feeling better about asking since I at least gave it a good go in the first place :)
