OBXT w/LGT Struts and OB Springs?
 
Howdy. Long time stalker, infrequent poster. :)

Currently have 05 OBXT down for TB maintenance and radiator replacement and I'm going to do suspension while it's 'off duty'. As a little background, its a 5EAT Limited Silver on Black. Current upgrades are EVO 16G, Cobb AP, Perrin Catless UP, Perrin Turbo Inlet, 06 center console. :lol:

Wanting to lower the wagon about 1-1/2". BC coils are an option, but I'm 41 and I'm past the point in life where I kidney damage is second to handling. If anyone had comments/experience that they're a) not that bad and b) of reasonable quality then I may still consider. Looking to achieve BMW firmness as compared to stock which I'd classify as Lexus floaty.

That said, looking at perhaps LGT KYB's for struts. As I understand it, the LGT's have a mounting point that's about 1-1/2" lower. Would coupling the LGT struts with OBXT springs get me to my goal? I've searched and not seen anyone attempt this nor have I seen anything that indicates it can't be done. I'm assuming I'd need to keep OB top hats and get LGT bumps. I'll be doing f/r bushings as well.

No offense but there are TONS of posts asked/answered on this exact question including this section.

Oregon OBXT 11-09-2012 09:32 AM

I did find a lot of LGT suspension swap posts. But all of them were full spring/strut swaps. My question was regarding the mix of LGT struts with OEM OB springs. I did also find this post showing the spring length comparison which has me maybe a little concerned about the rear coil fitment. But then this post for a 2G OB shows that it can be done on the previous generation, but without much detail about ride height, alignment, tophats, etc, nor any specific issues with the 3G OB.

Conversely, would there be the option of going with 2G OB Eibach Springs on 3G OB struts? This would probably be the best scenario as it would preserve tire clearance. Not sure of the ride quality, however, on the Eibachs...

The trouble I'm having is that I find a lot of folks who have researched options and then gone to either a 100% LGT setup or coilovers.

I don't recall seeing this combo either
 
So I guess you'd be on your own. Something tells me you'd be "cramming" the springs onto those struts. But I have to admit, that "spring length" thread had me wondering about the fronts.

I say we figure out where KTM lives and steal his Bilstein BTS's, and see what he does to recoup. It ain't that easy. But a member named Easton seems to have hit a pretty good "2nd best" option: from memory, he has Legacy GT wagon springs and Spec B shocks. Bilstein HD's and those springs might work too. In both cases, spacers between struts and body (upper mount) are probably needed. In effect, between the shorter (Bilstein) strut and the spacer, its basically just moving the spring further down the strut assemby, but same effect as the original longer OB strut. So they are using a SHORTER SPRING with the effectively LONG STRUT.

after reading the thread about Baja springs on Gen 2 Outbacks, I believe the Gen 2 springs are softer and therefore sit lower than our Gen 3 springs.

I have a little experience with Bilsteins on the rear, and hope to get them on the front soon, but I am NOT a fan of KYB twin-tube shocks (OEM or aftermarket) as spec'd for Outbacks. I would be skeptical of the Legacy KYB's being any better.

actually, you should also read this: http://legacygt.com/forums/showthrea...ight=koni+3.0r

I just got done shelling out a good amount of money on a custom-fabricated coilover developed by a suspension guru (understatement). When he lifted my Koni/Swift combo on his lift, we found that the rear's were resting on the bumpstops, and the front springs were almost entirely compressed. All of these parts were LGT wagon specific (sedan and wagon use same fronts). In short, it looked awesome lowered, but it was essentially rendered suspensionless.

Oregon OBXT 11-13-2012 09:21 PM

Fenominal, thanks for the input!

Just to clarify, you had lowered LGT springs on LGT struts on an OB, correct? So the lowered spring perch would bring you down about 1.5" and the springs probably another 1.2". That seems like a double-lowering and doesn't surprise me that it would put her on the stops. Out of curiosity were you using LGT bumps or OB stock bumps?

Oregon OBXT 11-13-2012 09:26 PM

So I'm now leaning toward trying these 02-04 OB lowering springs on my 05 with 05 struts. This should drop me down a nice 1.2". Is there anything that I'm missing in my understanding as to why this wouldn't work? I understand that the spring rate my be slightly different between 2G and 3G OB... I can shim slightly to level, and add/change F/R sways to tune handling. If this works, it would be half the price of BC coils, will be cheap/easy to replace the OB struts later, and retain close to stock ride quality, will provide proper tire clearance, and will look aggressive without being slammed.

Nope, I incorrectly used OB strut bodies to house the Koni LGT strut inserts and LGT Swift lowering springs. None of the bumpstop's were changed or altered. I do believe that Mueller shaved my bumpstops.

Good luck
 
Now we might be in a vicious circle. Better call JDMhub to check availability before you get too excited. i think this was covered elsewhere (see spring length comparison thread), I'm surprised they didn't remove them from their site. OTOH, let us know if they do have them.

LOL it ain't me you gotta pry the BTS bit from it's my wife. I do still have the Megan CO's and recently got replacement hardware to use with the new inserts.

Check this thread from OB.com, lots of great info on spring/strut/hybrid topics: http://www.subaruoutback.org/forums/...nsion-faq.html

After trying a number of options including Baja stuff on the OBXT if you wanna lower it use LGT bits with spacers to dial in height. Or luck into some BTS stuff and some extra $$$ like I did.

Or as I have come to decide buy a LGT wagon. Lowering an OB seems counter-intuitive unless it's for the manual tranny options after 2005 MY.

Oregon OBXT 11-14-2012 05:17 PM

Thanks KTM.

Starting with you last point, I don't disagree with you on 'just getting a LGT' statement. If one didn't own an OBXT a clean sheet LGT would be the way to start. In my case I already have an OBXT and have put $ into it due to a bad turbo. So rather than sell / re-buy I figure I'll just stick with a known quantity and build on what I have. I'm not looking to make it a trackable vehicle, just mod a little from what I have. I have seen some nice, tastefully modded OBXT's here and the uniqueness does add to the look IMO.

I have also read and posted on the subaruoutback.org forum. Good stuff there too, but no solution for what I'm looking to do. The only solid solutions that are well documented are coilovers or LGT transplants. The coils are spending and impact the ride quality, and a true LGT transplant lowers the OBXT more than I desire.

That said, I'm most likely going to try and source the 04 Eibach springs and pair them with OB KYB struts and see where that gets me. Hopefully the 04 springs will mate with the 05 perches and give me the slight lowering that I'm looking for.

I have contacted every/all vendors that list the parts on their websites when doing a google search and can confirm that nobody has them. Now I'm regretting having already purchase the KYB struts... should've just bought the BC Coilovers and been done with it. Bummer.

he tried to order from JDMHub

focus on posts 77 & 80

I have some Legacy wagon (OEM) struts & springs that soon may be up for sale

that BAC2 has some spacers to make all this more interesting for an Outback

Well... I guess we're going to do a little experimenting here. Got the 02-04 OB Eibach springs (7712.140) ordered this morning. I found them at a number of online retailers (including JDM Hub and eBay). I ended up ordering from Stillen based upon free shipping and reputation.

Hopefully this will achieve the roughly 1-1/2" drop (catalog says 1.2") that I'm looking for.

My plan is to get the springs in hand first so that I can validate fitment prior to getting the other bits ordered. Stay tuned...

Sideways the Seven 11-21-2012 03:58 PM

I confirmed over the weekend that the springs for the LGT and OBXT are different lengths and you could theoretically lower the OB by about an inch by swapping the LGTs in. Wouldn't recommended it though.
