I had started another thread about a week ago but it seems to have disappeared (not in archived).

So ... here we go again. I am wondering if a USDM ITR hub will fit on a JDM 96 spec axle since it is 32mm. Also, are the 96 spec JDM and the USDM ITR calipers the same? I think they both have 11.1 inch discs (front) and 10.2 (back), right? Also, are the rear lca's identical? I want to do a 5 lug swap as cheap and effortless as possible for the moment, and then later I will go for the 98 spec JDM setup for the bigger brakes.

 

I thought the JDM 4 lug was 36mm axle? If its a 32 I would think it would fit but not certain.

 

I also thought that for quite a while .... but as it seems the 98 spec is the only 36mm. Correct please if I'm wrong.

 

i thought the 4 lug jdm itr calipers were the same shizzle as the usdm gsr/ls calipers.

 

JDM 5lug is 36mm. 4 lug JDM itr or JDM non-itr is 32 mm just like usdm. As far as calipers i am not sure. I have heard that the JDM ITR 4 lug is basically the same as the usdm 4 lug gs/r etc but have no way to compare. Had several sets of these here but sold them so fast I did not have time to compare them.

 

Looks like the 96 Spec ITR/USDM GSR are 10.31 (front) and 9.41 (rear). Whereas the USDM ITR is 11.10 (front) and 10.22 (rear), So I guess my question now for someone who knows (len maybe?) is whether or not the USDM ITR hub and calipers will directly bolt-up with my 96 spec **** (using the USDM rotors too of course). Or will I need to change the knuckle too?

The ITR caliper will fit a GSR knuckle with some modification. You have to grind a small portion of the ITR caliper's casting off for rotor clearance, and it will bolt onto the GSR Hub. As for the rotor you have to redrill them for the 4 lug or you could order them predrilled from Fast Brakes. http://www.fastbrakes.com

 

JDM ITR 4 lug = 4x114
USDM GSR =4x100

JDM ITR 4 lug = 10.2 inch rotor w/ ITR/prelude caliper

So, you can't use the GSR rotors nor the calipers w/o shaving. Seems like a waste of time.

thats what i heard, i forgot where maybe best motoring?

jdm 4lug=32mm gsr/ls size rotors with type r calipers

So what your saying is the 96 spec ITR caliper and the USDM ITR caliper are the same?

Basically, all I want to know is will a USDM ITR hub/USDM ITR rotor/USDM ITR caliper combination work on the 96 spec knuckle.

If not, then will the UDSM ITR knuckle fit (or retrofit) on the 96 spec ?

Thanks!

 

All 94-01 Integra front knuckles are the same wether its JDM or US or whatever year. i checked OEM part numbers. To do the conversion, you need ITR hubs, front calipers (now discontinued from Honda) the caliper bracket, rotors, pads, and rear hubs, rear trailing arms, gsr rear calipers and ITR rear caliper bracket. You cannot buy just the rear bracket, you have to buy the whole caliper kit. Also you need rear rotors and pads from an ITR as they have different part numbers.

 

If I were you, I would purchase USDM 5 lug and sell the 96 spec 4x114 setup.

I would think that that would be most cost effective.

It's looking like that might be the best idea.

And thanks for that info B18C Turbo. Just what I was looking for. One question, how do the rear trailing arms differ from model to model?

Well this is where I'm having a problem. I am told that the casting is different on the JDM, but no one seems to be able to tell me what area of the knuckle would be affected by this. All I know is that I don't have enough rotor/caliper bracket clearance and it's either because the idiot that did my bearings pressed them in backwards (not sure if this would affect how far the hub goes in) or the knuckles are in fact some way different. Every thing else is OEM '01 ITR except the autozone rotors.

Please someone help me!

that last part is absolutely incorrect. 96-97 JDM ITR = 4x114.3 with 10.2" rotor with GSR/LS caliper and pads. i just ordered brake pads for my 97 JDM ITR and it takes GSR pads, *NOT* USDM ITR or Prelude VTEC.

Many people upgrade front JDM 4-lug ITR brakes to use ITR/Prelude VTEC calipers, rotors (11"), and pads, but that is not how it comes from the factory.

Please don't spread misinformation.

But how are they overcoming my knuckle and caliper bracket issue ?

This I will confirm too, as a friend of mine was recently swindled (he's new to tuning) by somebody selling him a "96spec JDM ITR BIG brake front kit" and sux to be him that he found out they were the same size as his Del Sol VTEC clappers.

to Unscrupulous sellers

You put a 3mm spacer behind the hat of the rotor. It's the same mod that many have performed on 4X100mm Civics/Integras.

So it goes (inside) knuckle - Hub - 3mm Spacer - rotor (out).

This usually renders the small rotor screw useless, but who cares when you got 4 lugs torqued to 80lbs.

 

or you can shim the caliper instead i believe.

This doesn't apply to my situation. My problem is that the bracket is hitting the outer face of the hub, not the inner. So by spacing the rotor away from the hub, I will actually be worsening the lack of clearance (the bracket wouldn't even slide over the outside of the rotor).

After switching to a USDM knuckle, and finding it to be the same as the JDM (despite being told by several people that they are indeed different), my dealership and I have narrowed it down to a possible incorrect caliper bracket. The front ITR calipers are discontinued, therefore I received a reman and it's possible that the caliper and bracket are not a match. We confirmed that my knuckles, rotors, and bearings are correct. Only things left are the hub and the caliper assembly. So I guess time will tell as will shoot 'em down one at a time. Damn them if all this has been because of an incorrect part in the correct box. Argh.

Yeah man .... haven't heard from you since Stone Mnt. BBQ 04 I think. How ya been? Think I've seen you post about a lot that you've done to the R.

Can anyone measure the ITR caliper bracket and tell me the depth?

 

At least someone can tell me the number on the ITR caliper bracket? Is it 25T?

Can someone look at this and tell me ? PLEASE !

 

Nevermind. Dealer had reordered the calipers and they came in today and I was correct about it being the wrong bracket (23T)(GSR?). These had the 25T so I'm all set to finish this ****.

I will be selling my JDM 4 lug off the car along with some Sprint springs and 18" Racing Hart C2's.

 

Just wanted to say I have the stuff off the R posted up here.
