Swaybar size and mount question

Icculus · 06-09-2008, 10:32 AM

Ok suspension gurus; did some searching but didn't find exactly what I was looking for. Let me first start by saying I will be doing the rear sway/end links first and leaving the front stock. The front will probably follow shortly down the road. Also this is on a stock spring/strut combo for now. Maybe TiC/RCE coilovers or RCE blacks w/Ohln's way down the road but will be rocking it stock for a while. Its a DD

EDIT: Don't think it matters much for this discussion but will be using either the Kartboy or the Cobb endlinks (most likely Kartboy)

The first question is regarding bar size. From reading around and looking at members experiences it looks like the recommended whiteline sizes are 24/24. So for the rear does this mean the whiteline 22 bar (adjustable to 20, 22, and 24) or does it mean the whiteline 24 bar (adjustable to 22, 24 and 26)? It seems like TiC recommends the 22 bar for a car on stock springs but if they both adjust to 22 or 24 whats the difference.

Second I see several companies (Cobb, Whiteline, Perrin) making uprated rear swaybar mounts. Are these really needed or just added insurance?

Thanks everyone

I personally feel that you don't need uprated mounts starting on the 2004 impreza. 20/03 impreza, yes. Starting with 2004 Subaru is using a stronger mount and it should be more than enough for whatever you throw at it.

As for the bar, I have found that 24 or higher on stock springs lifts the inside rear tire at apex on hard corners. By going with the big bar you could set it to the softest setting and be fine, and leave yourself two points upward for adjustment. Be going with the small bar you could run stock, one setting up from stock, and one last stiffest setting for when you upgrade the springs.

Thanks. So if i'm understanding correctly the 22 adj bar on the 22 middle setting and the 24 adj bar on the lowest 22 setting will function exactly the same (and the same sort of logic on the 24 setting). In which case it would be 6 of one/half dozen the other between the 2 bars as long as your running at either the 22 or 24 setting and the determining factor on which to buy would be if you are ever planning to run at either the 20 or 26 setting???

Haven't read to much on anyone running these settings (20 or 26). I've been basing most of where I'm coming from from your, Draco-REX, and stretch's posts. 26 seems stiff. Plus if the spring rate goes up I should be lowering (for lack of a better term) setting instead of making the bar stiffer right, so when would 26 be suggested. And if I read right the stock rear bar is already 20 (or at least 20 effective if it isn't solid, can't remember right this second)???

Also good to know about the up-rated mounts.

Thanks again for your continued outstanding support of the people on this forum

The what rate to run vs. the stiffness is going to be a factor of tires, driving style, and alignment.

Well its an aggressive DD but a DD none the less. Couple of auto-x days here and there but not much. Tires are currently RE070's and the alignment is not aggressive at all (can't remember the exact numbers right now.)

Sounds like the best option for me right now is to get the bigger bar and run it on the lowest (22) setting as you suggested until further mods take place. Just doesn't seem to make much sense to get the smaller bar when one of the settings is stock - I've got a stock bar for that

Definately go for the 24mm adj (22-26 equiv) and run it on the softer setting at first. Swaybars are very deceptive; small changes in their size make for BIG changes in their strength. You'll notice a big change in corners with just the 22mm setting.

Thank Draco. I've been following your Ultimate Street Setup thread and its full of great information (and the reason I'll be doing the group-N lateral link/trailing arm bushings along with the bar

).

After doing the bushings, you'll wonder why the car didn't come with them in the first place.

And I STILL need to finish that writeup... I need to stop being so busy and so bushed at the end of the day.

Dude don't sweat it. I know exactly what you mean. Work wears me out and I don't feel like doing much of anything in the evenings alot of the time. If i don't do my posting in while I'm at work it just doesn't seem to get done

Have you moved down to the smaller front bar yet? Like I said earlier I'm sticking with the rear bar for starters--one to try and get a feel for exactly how each part changes things, one to only have to pay out in baby steps-. I've been reading some threads about just leaving the front bar alone and I'm anxious to hear your reviews of the smaller one.

And if I didn't earlier, thanks for the info also Tony/Clint/mystery person behind the login

Not yet, I'm waiting until I install the RCA kit before I make a final decision.
