Default 2006 WRX Sway Bar Questions

Well i've had the car for a few days so far, and in going from a car with a full suspension to this I've noticed a few things.

1) I feel that the springs and dampers on this car are about right for my needs (seems like i'm in the minority here, but i think they're actually pretty firm!)

2) I feel there's a pretty healthy amount of roll, but nothign that's too severe.

3) The f/r bias is really dummied down for the general ease of driveability.

So where can you help me? Well i'm an auto-x man, been at it for about 3 years now. I also use my car for everyday driving. As a result i've always been a fan of big bars and less spring. This subaru is no different, it seems that the swaybars are really the weak link here in the suspension. How big are the stock bars? Will the previous sway bar kits (whiteline, cusco, cobb, etc) fit an '06 WRX? It seems that endlinks and mounting should be upgraded to, do most of the kits come with this?

I've been leaning (no pun intended) at a front and rear bar. The stock rear looks absolutely rediculous for a 3200 lb car! Thanks for helping me with my newbie WRX questions. To let you know what my end goals are: this car will be set up for ESP so I'll be running R compounds, more boost, perhaps some alky injection, and a catted TBE.

your front bar is 20mm

your rear bar is 17mm


Any 2002-2005 wrx (not sti) sway bar kit will fit on your 2006

Some kits include end links. some do not

My WRX is setup 20mm front, 20mm rear

My 2001 Impreza is now 19mm front 21mm rear

I love em both

Good news! Thanks, now it's decision time. How much of a PITA are these to put in? The front one on my focus was god-aweful, had to drop the crossmember out and all that jazz.

I can change the front without taking off the subframe, but it takes some work. Take off both tires and you can do it. You might have to jack up one side of the suspension to clear the tie-rods.

My only other comment is be careful about putting too big a bar on the rear. You may end up lifting the inside rear tire in a turn.

That's probably not a good thing to do with AWD eh?

No, it throws off the diff, plus you can't get as much power to the ground with a tire off. Having a stiffer front bar may help though. I have run my car without bars at all with 600/500 f/r springs, stock bars, and stock rear and 24mm front. You definitely want bars, but I would consider putting coilovers or stiffer springs and going with the stock bars. There are a lot of ways to handle this though.

The big thing is I don't want to increase NVH, but i'd like better control. I'm thinking a 22/22 setup would be about right for me.

ruggedman, I'm sorta in your position and goal for my 06 wrx wagon.

I just recently bought whiteline stuff which comes adjustable.

The front bar is wagon specific, and whiteline only has a 22mm as the largest available front. I got the adjustable one and it only has 2 adjustment positions.

The rear one is the same as sedan/wagon, and due to the size limit in the front on the wagon, I went with the 22mm adjustable.

Yes, but it is worth the effort to remove the subframe to do the install. It makes it a lot easier & it will go a lot faster.

R&R the subframe is no big deal. It's just 12 bolts. And you don't have to remove the last bolt on either side. You can loosen those bolts and slide the subframe off since the subframe is slotted for those 2 bolts.

Just my 2cents.

A stiffer rear bar like the 3 way adj. Whiteline bar (24mm), will not make a stock spring or even a STI spring, with stock struts car lift a wheel. It will allow you to tailor the car according to the course (autocross) all without affecting the ride... We have many customers with this set up and they love it!

A FRT bar is a great idea as well. A 22 mm frt bar will compliment the rear bar and help with lean and understeer. Frt and rear bars is the way to go for a balanced approach...

Don't forget about a good alignment! Most stock specs and settings on the car can be off, but the car will drive straight. A bit of negative Camber in the frt can only help (on a street car, about -1.5 degrees will work great)!

I couldn't agree more. I'm actually thinking the 24mm adjustable whitelines are what I'm going to go with both F&R.

Do the bars come with endlinks? Will I have to by those seperate?

ya i'm not surprised that a guy who bought a leather seated wrx would think the spring rate was stiff enough just playin

anyways if your looking for moderate difference cusco has a front bar thats 21 and also one thats 22(not sure if the 22 would fit though, its for the sti)
also cusco has a 22 mm rear adjustable bar thats pretty moderate, i've heard good things about it. its a good deal too.

you may like the stock struts.. i think there pretty good too, i still love having stiffer springs on though, i think that made a large difference, then again i'm only running a moderate 20f/20r mm bar setup ( i guess stiffening the springs made the effects exagerated?_)

Can't say how this works on pre-06, but I just did a set of sways on my 06 and I must comment that doing the front w/o removign the subframe is a "no go."
You simply have no access to the bolts which hold the brackets.
I was trying to weasel my way into doing it this way.......but there simply isn't enough room to get a grip with any wrench to break the bolts loose.
You could try, but the risk of excessive cursing and stripped bolts/knockles is extremely high.
...for what it's worth.

Endlinks are seperate, but many vendors can build you a package.
