Kind of a weird question, but has anyone used a smaller than OEM diameter REAR swaybar on their ITR? If so what brand and model was it?

It's a strange question to go smaller in diameter, but just looking for some fine tuning possibilities if needed.

Sorry, edited.

i know a cheaper alternative to add oversteer, is to go with the smaller LS front sway bar, instead of spending big bucks on a nice rear bar

 

^ Bingo.

If neccessary, go to a JDM 23mm rear if you need a bit more.

What are you trying to accomplish by doing this?

 

no mention if you mean front or rear.

front, OEMs run down to 19mm that should bolt right on, but you may need different end links.

rear, OEMs go down to 13mm.


Aftermarket, I'm sure you can get anything made, the ST front bar is ok at 19mm.

 

From what I've been told (i.e. I have no personal experience), 19mm front with 23mm rear is damn nice on the track.

Besides shock dampening, easiest final suspension tweak to enhance/reduce oversteer. Most people give the general response of "you want a bigger rear bar for better handling". So that's why I called it a "weird" question.

I actually have a '97 GSR with the ASR subframe brace. So it's putting my swaybar bushing locations in the same spot as a Type-R. And I'm going to run a 12kF/14kR spring rate. If the back end is way to loose when I'm ready to go I'm looking to see if something like a smaller rear swaybar is available for an easy adjustment. But not removing the ASR brace to do it.

There's larger and smaller front bars available, but the rear is the easiest so that's why I'm asking.

rear sway sizes available from OEM:
13
14
15
22
23
the ST 19mm works well also.


I had the same thoughts before I ran the first time.
I'm currently on a 10F/10R setup (EG hatch) with 22F/23R bars, and I'm currently looking for more steering.
High speed events are a little intimidating at first, so you might be better off with a little understeer to keep the ends pointed the right direction. But but once you get comfortable with the track you'll find you want more steering every time you go out.

you can also look into the ASR rear bar. It has adjustable end link positions that allow you to adjust the stiffness of the bar.

 

Thanks for the info. Actually, the high speed events don't bother me regarding oversteer. I have a CRX that I autocross that used to oversteer regardless of rear weight transfer. It was a 360° champion, and running with a full tank and putting a 40 lb bag of salt in the trunk actually lowered my lap times. That's been taken care of sense, but it seems harder to reduce oversteer than to increase it so I always try to keep the option available.

I have a 14 mm OEM rear sway, but it's a GSR OEM so the bends in the bar prevent it from being used with the ASR brace. The ITR type spacing for the bushings moves them slightly closer together, and unfortunately they line up with the bent part of the bar. I had the ST 19 mm rear bar on an old '94 RS, but due to the endlink location being on the bottom of the shock mounts the increased travel makes it act larger than it really is.

I was hoping to find a simple 19 or 20 mm bar for a GSR, but none of them seem to be strait where ITR sway bushings would go, except the ST but that option is out. The problem is that you don't even know, or can find out, what the bars look like unless someone installed one and can take a picture. I was hoping maybe a Tanabe or Cusco would work, but I have no idea what the bar geometry is. Calling the swaybar manufacturer is almost useless.
