XT-sub Posted November 19, 2016 Share Posted November 19, 2016 That said, torque values found in the Factory Service Manuals have occasionally been wrong. Ammcinnis, I’m guessing that is what happened seeing all three vehicles appear to be the same in that area. The rear clamp M8 flange head bolts appear to be class 8.8 (I can see 8 stamped on the head). I also agree with all your other comments. Link to comment Share on other sites More sharing options...
Milkywitness Posted November 19, 2016 Share Posted November 19, 2016 Well I put the 20mm on just now. I had a heck of a time getting it just right, but I can tell the big difference in ride quality. Cornering and even just driving seems so much smoother and flatter! I didn't go too hard since I wanted to get it broken in. I heard some weird noises though like it was settling in or something as I was driving, is this normal? Link to comment Share on other sites More sharing options...
brandon.mol Posted November 19, 2016 Share Posted November 19, 2016 Don't think so. You greased the shit out of the bushings, right? No chance it's hitting the spare tire tub? Link to comment Share on other sites More sharing options...
RobbieGT Posted November 19, 2016 Share Posted November 19, 2016 Common issue is that you didn't tighten the bolts enough and something is just ever so slightly moving around causing your rattle. Link to comment Share on other sites More sharing options...

I was thinking bushings as well. I love this thread...

PDREALTOR Posted November 21, 2016 Share Posted November 21, 2016 (edited) What is the part number for the White line adjustable sway bar that will fit the 2017 Legacy? Nevermind - it's BSR49XZ Edit again - 22 mm adjustable is certainly not worth the extra dollars to me. I went with the 20mm bar from Subarupartsonline.com . Threw in a cargo net for free shipping. Thanks for all the great info in this post! Edited November 21, 2016 by PDREALTOR Link to comment Share on other sites More sharing options...
bfkellogg Posted December 15, 2016 Share Posted December 15, 2016 I found a great price on the 20mm RSB. It does not come with bushings but they are cheap to add and on the same page. Everything plus shipping came in just under $85. http://www.generalmotorspartsonline.com/oe-subaru/20451va000 Link to comment Share on other sites More sharing options...
MrCobbs Posted December 18, 2016 Share Posted December 18, 2016 I didn't want to create a new thread after searching I hope this is the appropriate place. I am in the process of ordering the 22mm RSB from Cusco but a Subaru Tech advised to buy a brace as he sees a bunch of broken and warped mounting parts come into the shop on the older Legacy's. I didn't want to go back and ask him but before I do so does anyone here know if this will fit our cars? http://i.imgur.com/wuuG412.jpg http://i.imgur.com/aWw9nYK.jpg Link to comment Share on other sites More sharing options...
TruNoLies Posted December 19, 2016 Share Posted December 19, 2016 I have only seen one site offering the 22mm swaybar and I myself was wondering if it would make a big impact or if the 19mm would be enough. I think it was Whitline that was selling the 22 and if i'm not mistaken it came with all new hardware (bushings, and mounts). Please keep us informed of any improvements you find.

ammcinnis Posted December 19, 2016 Share Posted December 19, 2016 (edited) I ... was wondering if ... the 19mm would be enough. My opinion: Yes, unless you have a specific reason to go larger. The OE 16mm RSB is clearly "enough," and a 19mm bar is going to be twice as stiff as that. Bigger is not always better. (FWIW, I have a 19mm RSB installed in my Legacy.)

fredrik94087 Posted December 21, 2016 Share Posted December 21, 2016 MrCobbs: If it is a part listed for a 2008+ WRX for the rear suspension, it should fit.

Sent from my SM-N920T using Tapatalk Yeah I was looking at that set but I've seen people complain on here about it rusting up. Being here in the northeast I was trying to avoid that.

BradLegacy2017 Posted April 12, 2017 Share Posted April 12, 2017 Thanks for the write up. This is going to be the first official mod to our 2017 Legacy after it's first oil change at 6k! I can't believe how much body roll they allowed this car to have. It's so bad my wife swears that her 2002 Ford Escape handled better and can't take turns as fast in the new Legacy. My question for those who have already upgraded their rear sway bar to 19, 20 mm ones. Did you notice any difference in how the car feels over bumps, dips, etc. In other words, while we are stiffening things up with the rear sway bar, does this cause it to possibly ride a bit harder? Thanks. Link to comment Share on other sites More sharing options...

Not objectionable, IMO, but noticeably stiffer/harsher on some road surfaces. (I have the 19mm RSB, which is twice as stiff as the stock 16mm RSB.)

The Grey Goose Posted April 12, 2017 Share Posted April 12, 2017 I have the 19mm, and it seems to ride harsher over uneven road. It's hard to definitively say because I upgraded it two weeks after buying the car, so I forgot what oem rides like. Link to comment Share on other sites More sharing options...

I figured it may ride a bit harsher since we are indeed stiffening the link between both rear wheels (from a suspension standpoint). I am assuming though that the improved handling from the reduction of body roll is worth it, regardless of any decrease in ride "quality". Link to comment Share on other sites More sharing options...

I definitely plan on going with the 20mm. Now if I could only convince the wife to let me do it sooner than later!! :-D She is having some difficulties understanding the need to modify a brand new car. LOL. Is it so wrong to want to make it BETTER!? Link to comment Share on other sites More sharing options...
ammcinnis Posted April 12, 2017 Share Posted April 12, 2017 (edited) She is having some difficulties understanding the need to modify a brand new car. LOL. Is it so wrong to want to make it BETTER!? Not wrong ... but the stock 16mm RSB is perfectly adequate for most drivers, under most driving conditions. The Outback actually benefits more from a stiffer RSB than the Legacy, even though both share the same platform, due to the Outback's higher center of gravity.
