Are there any front sways for the SI?

I cannot find any front sways. I know there was a Progress one that i wanted to pair the rear one with and now its not available.

Are you looking for larger or smaller?

I believe Einbach has a 32mm hollow front bar.

I'm not sure because the progress rear is 22mm and I don't know if I should get another 22mm or a smaller or a bigger one.

What do you think would be better to pair with the progress rear?

I ran the Civic LX front sway on my last Si and the grip going out of corners improved quite a bit. There was a little more body roll (obviously) but corner-exit understeer was dropped.

Ah, yes, the LX front bar is a good choice to pair with the Progress rear.

some guys run no front sway with autocrosses...they control the roll by beefing up the spring rates

I'm not autocrossing or anything right now. Do you think it is okay to have just a stock SI sway in the front and a progress rear in the back? I also saw that thing where peoples endlinks broke with the RSB. Was that only on the non SI's?

People aren't breaking the endlinks, they're breaking the mounts. So, it shouldn't matter if it's an Si or not, if it's going to snap it will

But anyways, Si bar front and Progress rear is still better than stock.

Apparently that's why. But really, I think it would be better to have a stiffer bar up front to decrease body roll and that's what I'm looking for.

I have the eibach front sway (32mm) and rear sway (19mm) bars and the car's weight balance is a lot better. The rear sway bar is adjustable also, I have it set on the stiffer setting.

I dont know. 19mm doesn't seem enough to justify the money spent. I mean stock it's 17mm.

comparing by mm doesnt justify its stiffness. the bar made by eibach/progress will tell you its stiffness % over stock, which is what you should look out for.

A smaller bar up front makes no sense to me either. Somebody will correct me if I'm wrong but if you don't pair the front and back, the backend will be stiffer and the unloaded rear tire could actually lift off the ground.
If you set the camber correctly with the SI or stiffer front sway bar, I don’t know how by using an LX it could be faster in the turns. It doesn’t make logical sense to me.

You obviously don't understand weight transfer and the effects on traction then.

While if the rear roll stiffness was excessive it would be possible to 3-wheel, just the progress rear and LX front will not get anywhere near that.

ummm just to let you know and to give you some must needed information...what determines whether your car is neutral, understeer, or oversteer is the RCD or roll couple distribution. basically the difference between the stiffness from the front when compared to the rear of the car...the stiffest part of the car will give out first so a stiffer front end will break traction before the softer rear causing understeer...alot of stock si guys run a bigger RSB and a smaller LX front sway to offsett our nose heavy, static camber gain, macpherson strut front suspension cars...this not only makes the front end softer ...which is what you want...but also stiffens up the rear for throttle lift off rotation and rotation in general in tight corners...this is the optimal setup/fastest setup for track...the fastest way a fwd will make it around a track isnt a neutral setup but a slightly oversteering setup...usually accomplished by bigger rear sways and rear spring rates over double that of the fronts...

a perfect example is the realtime acura rsx...over 150 000 dollar car and the slightest inkling of throttle liftoff the rear end rotates and causes oversteer...it takes a profressional skilled driver to master that fwd setup but when it works it WORKS...

Just letting you know there are plenty threads on suspension theory, toe, camber caster, alignment specs all stickies....please read those and you will most likely find the answer yourself in which you will learn more then just asking people for the answer!

I run lx front sway for weight savings not traction.

You're right, I'm just learning, i think I get it though, putting more pressure on the loaded rear tire will give you slight under-steer.
I remember autoweek tested some $hitbox and got the rear wheel to lift off in the slalom. That what gave me the idea of balancing the front and rear sway bars.



Edit: I've got more reading to do.
