Default Proper swaybar sizing.

Ok so I'm going crazy on trying to decide what sizes to go with. As of right now I have S2 Pro-S Coilovers. I believe they're 12kf 10kr I'm not completely positive. I need to pull part numbers and look them up.

What sizes are recommended for some auto-x and future HPDE? I'm looking at eibach and suspension tech. The Eibachs being 26mm front, 17mm rear, and I'm aware that I'll need a rear subframe brace. The suspesion tech is 1" front 3/4" rear. (25.4mm F, 19mm R)

I dont want something thats going to get tail happy, which would make sense with a larger rear sway. I see these ASR packages with like 26mm and 32mm rear sways. I dont understand why anyone would need one so large.

Car: Civic DX sedan
Suspension: S2 Pro-S
Bushings: Poly <-- garbage. Going to install some hardrace soon.


Just curious what everyone is running and what their overall opinions are. Thanks in advance.

a 92 dx sedan. holy ****. can i have your kids??!!!

anyhow my daily is an ex so it comes stock with 19f and 14r(i believe..**** is tiny). i run a rear biased sprung setup also removed my front arb. i love the way it rotates and handles.

alot of this is going to be IMO talk...so with that said you need to know how you want the car to act/react and go from there.

ps give me your car!! or ill trade you power windows for them manual boys. lol.

Honestly, about a month ago I was considering selling due to lack of funds to build, But I've managed to stick with it.

lol btw. My sedan is the fugliest color scheme honda ever came up with. Baby **** green with tan interior. I want to paint it soon.

I dont really want the *** of it too happy so I really just want a neutral setup. I dont like the way it plows right now, something has to change. With no swaybars its really not that fun.

and I would never trade my lightweightness for the classy power options lol. Still has power steering that I enjoy very much.

well if you want it to be neutral then i would suggest to put the ex front arb on and a 22mm out back with the spring rates you are running. set your front shocks on full soft and rears on full hard. should rotate really well but wont be "tail happy".

The Pro-S Dont have any dampening adjustments

I want PIC Selects.

And btw. What rear bars are compatible with the ASR rear brace? or should I go with an ASR rear bar?

yes you will need the asr or beaks kit to run an arb without ripping the **** out of your subframe. all arbs will work with it as long as you have compatible d bracket bushings to hold it right.

Ive read about problems with the stocker fitting back there as to where the location of the bend is.

The asr subframe supposedly moves the bushing mount a few inches... is there anyone who can shed some light on this?

that is true but you also lower your car which changes the "mounting" angle of the arb. there is adjustable endlinks if you find fit.

"tail happy" is a term that's relitive to what you use the car for and what you're used to.

oversteer and understeer are all about tuning the car for your needs.
With sway bars, I'd suggest sticking with OEM peices for now. Cheaper and they fit perfectly.
If you're planning on doing some HPDE and autoX events in the future but mainly the car will be daily driven, I'd suggest going with the typically used OEM ITR setup (24mmF, 22mmR), it should be a decent balance with the coilovers you have. It will be noticably more tail happy than you are now and will take a little practice to get used to it, but it's far from uncontrolable. (be carefull when hard on the brakes with the wheel not centered)
If you find you want slightly more oversteer (or less understeer) either drop down to the stock EG 22mm front bar or go up to the JDM ITR 23mm rear sway.

As you do more and more actual track time most people find that they want even more oversteer, so the addition of the 26mm or 32mm rear is in order.
Some go as far as removing the front sway all together. But I don't suggest that for anyone that hasn't done some serious driver training and taken their time getting used to the way the car behaves.

I was considering going with the stock pieces. But that Eibach combo (26mmF 17mmR) sounds like it would maintain the way the car plows slightly now. But its also more expensive.

btw. Thank you for the very informative post. I've been reading a LOT on suspension theory and trying to get myself setup chassis wise before I build my motor.

i'm with relic on most setups, either use itr bars or in the back you can also use the st 19mm since it mounts on the shock bolt, it de-levers from the itr style making it act larger than it is on the car. you almost never need to go above stock on the front sway. again, spring rates also effect what size you use. same with intended use of the car.

So, Maybe I should start out with an ITR setup? (24mmF 22mmR) I wont be pushing the car hard on the street. Only on the track, so I'm not too concerned about street performance.

The ST setup is 25.4mmF and 19mmR and that sounds like it would maintain the slight plow I have right now. So I might be going with that setup.

And I'm not really worried about where they mount, as long as they're compatible with an ASR rear subframe brace. I already have SPC lca's that accept endlinks.

no, no, don't use the front ST bar, only the rear. couple it with a factory 24mm
