I have a ITR rear bar but not sure if its JDM or US mainly because I don't know if there is even a difference in size.

Is JDM larger or is it the same as USDM, I need dlinks and need to know which to buy.

Edit: USDM is 22mm and JDM is 23mm for those who also are wondering

 

Is his edit correct?.. I would also like to know baout this..
And does anybody know if there is a difference in the Front sway bar? between the usdm and jdm?.. wut about the gs and gsr? wut size are they?

 

Usdm front is 22mm on the ls. I'm 100% on that. I think the usdm gsr and itr is 24mm. I know jdm itr is 24mm for sure. A quick search will answer your question for sure.

 

This info is easy to find...

USDM GS-R 24/14
USDM ITR 24/22
JDM ITR 25/23

 

This would be correct.

 

I've seen numerous sources online say that the JDM ITR had a 25 mm front sway. Perhaps someone else can settle this.

 

OK, I rechecked my JDM EPC for the ITR front sway part nr:

The DC2 SI Integra has the 24mm part nr 51300-st7-003, while the DC2 Type-R has part nr 51300-st7-z11, so this probably could be 25mm (but I can nowhere find thickness info).

 

I had trouble verifying as well. I know I read an article recently talking about how the JDM ITR had an increased front sway to somewhat counteract the oversteer added by going from 22 to 23 in the rear. Can't find the article so I don't know how reliable the source was. Maybe this info isn't so easy to find after all!
