Smile I want Swaybars! Couple of Q's for ya

Hey guys, I'm currently thinking about my next mod (), and I've settled myself on swaybars and endlinks. I've done a bit of research and I've read the Swaybar FAQ in the suspension forum. I've also read some reviews from people who have installed different set ups, and based on my research and those reviews, I've reasoned that a solid 26-28mm front and a solid 22-24mm rear would work best for my needs. I currently like the way my wagon rides during daily driving, but I want more stiffness in cornering. I may upgrade struts/springs in the future, but they are staying stock at least for the winter. I'd like to think that I'm a solid driver overall and I'm looking forward to working my way into autocross come the springtime.

Are these good sizes for a mild to aggressive setup for the street and beginner auto-x? And the suspension changes as a result of installing the swaybars are fine for winter driving as well, right?



Thanks PNWers, I really appreciate the help!

The sizing sounds good to me.

As for winter driving....if it gets especially nasty out, you may want to disconnect the rear (maybe the front too?).

From the WRX's/STi's I've driven... they are very prone to understeer. What is up with people putting such a thick bar up front? Especially when you have it bigger up front than in the rear. That would only create more understeer. I'm guessing there are some pretty solid endlinks out there to help compensate?

Running swaybars that thick, should make a night and day difference. Only con I noticed on my buddies WRX is that it tended to create a couple of rattles inside every so often. But the car was fairly well balanced with the H-sports and h&r springs. He did just fine in the snow also.

There's been an enormous amount of posts regarding this subject, but to sum it up, adding a big front sway works very well.

OP, you probably only want about 24-26 max up front (I would just get the non-adjustable Whiteline bar, that's what I had on my wagon).

Driving in the snow couldn't be easier since you can steer the car with the throttle much better than stock.

good to know guys, thanks.

Beeej: this is the thread that I read prior to posting. It explains the use of a bigger front sway bar... I guess just start at "what size should i get" a section or two down explains the reasoning behind it.

I thought it was a great read, and made sense after a few times over.

The non-adjustable bar you had on your wagon is wagon specific, correct? and it was what size? It sounds like you mean the front bar, but I don't know what size you mean..


again, thanks a lot, keep it coming!

I know some people will bag on Perrin products, but I like the idea of their adjustable 19-22mm bar for the front. Meaning you could set it back to the stock setting for offroad driving if you wanted to, or up to 22 for street/autox. But the whiteline bar is very nice also (and you can get both adjustable and non). I'd say 24 up front is plenty.

I have their 22 rear adjustable bar and I like it, though I've never actually adjusted it.

Hi guys, I installed cobb springs on my STI awhile back and just installed the 25 mil hollow bars last week. I did the rear bar first and drove on it for a few days. After the front bar(factory endlinks all around) the ride was almost better than before. Its stiff but works very well without harshness. Now I'm ready to install perrin endlinks all around. Cant wait to feel the difference. The tendency toward understeer seems almost neutral although I havent had a chance to drive it really hard in the same spot I normally test handling. I like the hollow bar, and I was worried the front bar would induce understeer. I guess cobb may know how to assemble a package as these were all part of the stage 1 handling kit. P.S. the rear strut tower brace was more noticeable than all these for rigidity.
