I agree. After putting in a Pioneer HU the stock premium speakers can actually pack a punch.

I dunno.. Never ran sway without them being on there, they came in the kit.

I'm not sure how much the swaybar would move back and forth with them gone, but even if it moves a little bit, I guess that could make a difference.


Another thing is that the lube would tend to stay in there longer if the swaybar stays in one spot as opposed to sliding back and forth even an inch.

I'm wondering, does the stock setup not have those "keepers"? Does the stock swaybars move back and forth? Maybe that is the extra clunks happening once in a while? Maybe they should be left off so the bars can move back and forth?

All questions I never really thought of before now.. Hmmm...

So I know the auto impreza has 'Active' AWD so it's front wheel drive normally and switches to all 4 on demand, whereas the manual is continuous AWD. If I turn off TC on my Active AWD auto does that make it continuous AWD? I don't think it does but just wanted to know for sure.

The 08-11 auto cars are 60:40 fr:rr split, going to 50:50 under hard acceleration. There is no 'front drive only' unless you pull the awd fuse. TC off only allows all 4 wheels to spin under low traction conditions eg. Snow.

Some quick pictures of the KYB/King Springs combo. Tires are currently 215/50/17 but I'm trying to get a set of 16's with 215/60/16.

How much lift is that?

I could probably get at least an inch with my current set-up. I wonder if I should lift it for the lulz.

~1.5". My wheels now give it just under .5" more than stock. When I go to 16's with bigger tires, it'll give me another .75".

No the locks don't come stock. Whiteline has them and I think the bar moves a little or at least the locks prevent the slightest movement which is probably good for the endlinks. I didn't grease my oem bushings when I installed them?

I got a White Line bar recently. They switched to a new type of bushing. It is a grease-less bushing. It has small hairs on the inside to to help with the movement of the bar. Also it doesn't come with locks. Although the bar helped with sway a lot I feel as if the locks would restrict a lot of the movement I still get.

Oh yeah that makes sense that the collars would help take stress and strain off the endlinks. I think stock is rubber (softer) and maybe doesn't need lube- the rubber just squishes around and moves with the bar, possibly? Not sure.

I just was looking at my urethane bushings (FRONT) as I am going to get them installed on Fri with my NYS inspection..

They have little scalloped squares running down the center where the grease would sit. I guess I forgot about that or didn't notice that while installing rears.

Okay... they're not that bad, but still pale in comparison to the Pioneer's I replaced them with. The new speakers sounded much better with the stock head unit (which I replaced later), and I never tested the old speakers with the new head unit.

I also picked up the stock under-seat sub which filled in the lows perfectly for me.

I think the main difference is the center diff in the manual is all time viscous locking diff w/50/50 split, whereas the auto is a front biased F/R split, but has ability to go more to the back instantly on demand via electronically controlled center diff. I am not sure if it is actually "only" 60/40, or if it can "only" do 50/50, or if it can do more front or more rear in certain situations. I tend to think it can.

Manual is "passive" and Auto is "Active".


VDC also uses brakes via 4 channel controller which I think can effect the diff as well, used as sort of a locker, via brakes on one side or the other. I think some of the algorithms are actually proprietary (a secret).


Anyways..

I was on cars101 checking the curb weight and found the AWD section so that's why I asked lol. So auto is "continuous" AWD just more of the power is distributed to the front axle during normal driving conditions. Then, when needed, it will go 50:50 or another ratio depending on the circumstances? It confused me when it said "Instantly delivers power to the rear axle on demand" sounded like it's FWD normally and sends power to the rear in snow or something. Missed the front axle 'biased' for some reason lol. Thanks for the clarification guys.

I don't think Subaru comes right out and says "60/40" then 50"50"when needed. It might be only those two or in between those two.

But you see that if you read what they (Subaru) say exactly, it could be 100/0 front, then 100/0 rear.. but We kind of know it is not that extreme, but who knows how far it really changes to the front or rear. I doubt it goes more than 50/50 to rear though. I have a suspicion it might go more than 60/40 front when driving down road on dry pavement, but really , we're all just guessing, unless someone else has some concrete data. Maybe they do?

That's really odd that no one truly knows the power split for the Active AWD.. Oh well guess I'll just slap a DCCD on my car so I know and can control it, also might as well manual swap it while I'm at it. With all the money I don't have..

I'm sure someone knows. Maybe it is 50/50, 40/60, but the reason I think it might be more than 60/40 is the gas mileage an auto can get compared to manual. I think a manual would get MUCH better mileage if auto could only do 60/40 cruising down highway on dry day. It leads me to believe that it may decouple all the way to basically "FWD".. but then instantaneously give power to rear when needed.

but how would you test that?

So what happens when you do a tranny swap? Since they have 2 different AWD systems. Change the c-diff too?

On a side note... Taking my car into the stealership Saturday morning to get my Brake lines checked out for the recall.

My brakes have actually been terrible lately and I was assuming this is the reason, since my car sat outside about 3 years of its life and my brake pads are fine.

The center diff is inside the transmission.



This is also why you never want to damage your center diff. It is not easy to fix.

I got the 60:40 50:50 info from the Subaru literature that I still have from when I bought the car new. Doesn't always mean it's accurate but....

Looking good! Can't wait to see it with the 16s on there. Do you have any skid plates or the rear diff cover on there?

I really wanted to go the KYB/King Springs route, but it was just not in the budget. Post up some more photos if you go on any off-road adventures, that way I can live vicariously through you!
