You don't really want to go to a thicker sway bar up front. The whole point of going with a thicker rear bar is to bring the balance of the car away from understeer and increasing the roll stiffness in front encourages more understeer.

Oh btw, the '98-up JDM ITR did come with a 25 mm front bar. The '99-'00 Si coupe does have a rear sway bar as well, not sure if it's the same 19 mm as the Integra or something thinner like the Civic EX.

Regardless, the stock GSR front sway bar is the way to go.

 

19mm rear? 13 for LS, 14 for GS-R and 22 for ITR is what i was told...

 

Yeah you're right, I was thinking 4 and hit the 9 key. :doh:

 

phew, i was afraid that all this time i had been misinforming people

 

the 96 ITR's had 24mm front sway bars and the 98-01's had 25mm. USDM 00-01 Integra LS/GS have 24mm sway bars. just letting u know

 

Sorry, I just checked the part numbers and they are identical for '97 and '01 ITR front sway bars.

Only the '98-up JDM ITR has a different front bar.

 

I've never heard that the Swaybar for JDM models changed and don't see any reason to think it did based on speculation. The JDM REAR swaybar is 1mm larger but there has never been any discussion about a larger front swaybar.

The 97-01 USDM ITR FRONT Swaybar is 0.94" according to the brochure which is 24mm (Actually slightly less)

 

will a ITR rear sway bar bolt right onto a 98 LS?

 

It won't bolt right onto and you will need to consider subframe reinforcement to prevent severe camage to the subframe.

I'd suggest looking here: http://www.beaksproducts.com/main.html

Note: The reinforcement kits to NOT gurantee tthat the subframe wwistand up to the forces subjected to it by a larger swaybar.

 

Yeah, the USDM ITR has 24/22 mm sways front/rear. I was under the impression that when the '98 JDM ITR got the 23 mm rear sway bar its front bar grew to 25 mm to keep the overall balance front-to-rear about the same, but I can't remember where exactly I got that info.

For all intents and purposes though, we can just say that for an Integra the best thing to do is stick with a 24 mm front bar.
