  1. Thanks! Please let us know what your impressions are of your new sway bar on a non-locked sub frame. FWIW, I'm still running the AVO braces with a 19mm JDM sway bar, but I did the braces first and then the sway bar. Each made a noticeable improvement but I'm curious how much an improvement just the bar would have made.
  2. Interesting, I didn't even realize there were other options for sway bar braces for our cars. The AVO braces shouldn't be compressing the rubber mounts. Well, at least not anymore than they were originally. The bushing setup is exactly the same as the rear bushing on our front control arms (20204AG011). Their overall diameter is smaller but it appears to be the same inner sleeve, rubber with voids, outer sleeve arrangement. The AVO brackets mount to the bushing's inner sleeve and bump stop (20176) with bolt (1). Bolt (1) then gets torqued to the factory spec of 129ft-lbs so it's not compressed anymore than it was before. I have been thinking about alternate ways of reinforcing the mounts without restricting the motion of the subframe but the car is so much more pleasurable to drive with the AVO braces. (And that's with snow tires installed! Really looking forward to getting back onto the all-seasons.)
  3. Nonamedude, I forgot to ask earlier, did you install the AVO braces along with the 20mm rear sway bar? Or, are you running only the 20mm bar on the stock mounts?
  4. Thanks all. Definitely can relate to that weird and uncomfortable feeling in the curves and that's what motivated me to do the suspension refresh. I've been keeping an eye out on ebay for JDM rear sway bars. That and KTA124 are really the only things left on my original to do list.
  5. Thanks for your comments everyone. I was just amazed at how much of a difference it made so it definitely eliminated some flex somewhere. I'm very happy with the result but was worried about what might happen when I take the car on some rougher roads. It's good to know that nobody seems to have had any problems. Of all of the things that I've done so far in the car's mid-life suspension refresh: new KYB struts on all corners, new sway bar end-links on all corners, new sway bar bushings on all corners (new oem rubber in the front, polyurethane in the back), new aluminum front control arms with the solid mevotech rear bushing, installation of a strut tower brace; the AVO braces probably had the most noticeable effect on the precision of how the car handles through curves (on Highway 99, Vancouver to Squamish and back). Before that it was hard to "feel" the curves and the rear would seem to wander. The tail still feels like it sticks out a bit in curves at higher speeds but it's much more predictable and consistent. (Would a thicker rear sway bar help with that?) I suppose it's possible that the AVO braces were the last piece of the puzzle needed to get the car's suspension back to a respectable state and that's why it felt so dramatically better. BTW, the rubber subframe bushings on my 2008 2.5i are actually similar to to the OE rear bushing on our front control arms in that they have voids in them. They looked OK but I do wonder how much they have softened up with age. I purchased the car used (with about 60,000 miles on her; now she has about 130,000 miles) so I never experienced how the car handled when new.
  6. I guess I'm missing something. To me, it seems the cylindrical mount of the AVO brace is securely fixed to the chassis by the large bolt: (1) in the diagram. At the same time, the AVO brace is securely attached to the subframe via the sway bar mounts: [A] in the diagram. I just don't see how the subframe can move freely after that.
  7. That's true for the two points where the AVO brace mounts to the flimsy swaybar mounts. But the third mounting point, the cylindrical section, mounts using the same bolt that appears to mount the subframe to the chassis. Have a look at the photos in this thread: https://legacygt.com/forums/showthread.php/did-install-my-avo-sway-bar-brackets-correctlyi-147933.html The large mounting bolt in the first picture clamps the cup/stop (the part that was inverted in that thread) and the AVO brrace to the center sleeve of the rubber isolation bushing to the chassis. So we are essentially nullifying the effects of that rubber bushing which probably explains the large improvement in rear end stability I'm experiencing despite not (yet) changing the rear swaybar.
  8. About a month ago I installed the AVO rear stabilizer mount braces as part of my car's mid-life suspension refresh (2008 2.5i Sedan). During the install it dawned on me that the braces actually lock the rear subframe in place: the braces attach to the subframe (via the stabilizer bar mounts) and then bolt onto the rear chassis-to-subframe mounting points thereby locking it to the chassis. Am I mistaken about this? Assuming this is the case, has this caused any issues for those of you who take your vehicles mild off-roading once in a while? (Bumpy forest service roads, gravel roads, etc) BTW, the difference in handling by just installing the AVO braces was huge. The rear end of the car is so much more predictable on curvy highway sections. And, this is with the stock 15mm rear sway bar. In fact, the improvement is so pronounced that I just might call it "good enough" and live with the skinny 15mm sway bar.
  9. Ha ha. The car is not too bad actually, just the usual dash rattles that Subies of this vintage had. I'm more concerned with V and H as opposed to noise as these cars never had much sound insulation to start with. I find noise levels acceptable on the highway, just don't want the ride to be too jarring when you hit an imperfection on the road.
  10. Thanks, that's great to hear. I don't have access to a shop press and Whiteline's kit look like nice "swap and play" solution. Since my car is a daily driver, I really only have at most one day to finish the job so I'm leaning towards this kit instead of improvising something to press out/press in bushings on the existing arms.
  11. I'm in the process of replacing all the tired and worn suspension bits on my 2008 Legacy 2.5i. For those of you who installed Whiteline's KTA124 in the rear, did it increase NVH much? My car is a daily driver and I don't want to add too much NVH to the setup. Thanks, David
