I currently have a 92 VX hatch on Tein HA's (8/7 rates) TypeR LCAs, all new oem bushings in the car, Skunk 2 Pro+ front UCAs, and rear Intrax camber arms with a proper alignment with a bit of extra camber added over OEM spec, and a front strut brace.

I was considering getting a Beaks kit and adding a OEM SI rear swaybar or a GSR rear swaybar, but I am unsure if it will cause more benifits than it will good.

I understand how swaybars work and the psysics behind it, but I am not looking for a setup where if I touch the brakes my car spins out, or excessive oversteer, I would just like to remove some bodyroll.

Also I do not have front swaybar mounts in my LCAs only rears (ITR lcas)

What would you suggest to tighten up the feeling of the car a bit?

I've frequently read that swaybars are used to control handling dynamics rather than body roll which is often controlled by spring rate. Perhaps someone else can shed more light on this.

Please be more specific on what you are trying to accomplish. If you would like the car to rotate a little bit easier then yes a rear swaybar would help. The rear swaybar will also help stability during hard braking.

It really depends on what you would like your car to do.

I would like the car to have a more aglie transient response, left to right etc, and have less body roll.

PIC Performance

Swaybars have little to no effect on straight line performance, assuming the car is going over a relatively smooth surface. So they aren't going to help under hard braking, and they won't make the rear come around if you hit the brakes. They equalize the load between two tires along the same axle, so unless one is more heavily loaded than the other (eg. cornering), the swaybar will not function.

Swaybars are a good upgrade for almost anyone looking for a good bang-for-the-buck upgrade, as there are many options out there to suit many needs, lots of which are OEM.

The OEM Si and GSR rear swaybars are silly thin, you're not going to need any reinforcement with those.

Another good upgrade might be tires, but that will depend even more on what you intend to do with the car - you trade off treadwear for grip.

Awesome post, I am running some Azenis right now.

So basically you feel a SI or GSR swaybar with no front bar would be a good upgrade and not give me silly oversteer or make the car too unbalanced?

The Si and GSR bars are indeed pretty tiny. Rough estimation, eyeballing swaybar motion ratios (guessing around 0.6) gives you a cornering wheel rate increase of about 30lb/inch for the SI ar and about 40lb/inch for the GSR, roughly 7% and 9% increases in rear roll stiffness respectively, which unless you have some funky alignment or tire issues shouldnt be any problem.

For perspective, a type R bar in the back would be a nearly 56% increase in rear roll stiffness, which people have successfully done before. The long-term success of that I dont know, but it has been done

Throwing on a front sway will make a good difference, oem bars either from a civic ex/si or integra will do the job. As for the rear, a simple oem si/gsr rear sway setup will def be a upgrade. I've compared my ej8 with my little brothers stock EM1 and his car is def stiffer stock for stock. The EM1 does run the bigger 26mm front sway but that 13mm rear sway really makes that much of a difference(well at least in my opinion). I'll be throwing on a 14mm gsr rear sway on my ej8 tomorrow, i'm sure i'll be happy with the results.

My friend got an S2000 rear sway bar to work on his 2000 ITR and he said it improved cornering vastly over the stock ITR bar (which is a pretty descent diameter itself). The GSR bar is really thin like everyone else was saying. I was just looking at today and comparing it to another S2k one in the shop wondering if I could get it to work on my car. Can't remember exactly what needed to be done for it to fit, whether a mounting plate had to be fabbed or not...I will find out and get back to you tomorrow if possible.

Lots of good information has been passed here. I'd just like to add if you do decide to add a GSR/Si rear bar, you won't have a problem with oversteer. I'm running a rear 19mm Tanabe bar paired with PIC Select coilovers (10f/8r) with no front bar and I do not have a problem with excessive or snap oversteer. To answer your thread title it will be beneficial, but not by much, although it is an easy and inexpensive upgrade.

goldegg

Thanks alot for all the good info!

To put a GSR bar on my EG with ITR lcas, would I need to use ITR endlinks on the GSR bar?
