Mods: If you feel this is the wrong forum, please feel free to move it-I just figured one of you ITR guys might have run into this problem before...

I need to replace my rear trailing arm and I was'nt sure if there was a difference between the rear trailing arms on a GSR and an ITR , mainly if the fact that one is 4 and the other is 5 lug being the concern. Reason being is that my friend has a rear trailing arm he is willing to give me for cheap but it is for a 4 lug setup

So I guess my question is will my friends rear trailing arm from his 4 lug work on my 5 lug setup?
TIA guys

 

would it fit? yes.. are they the same? no.. and not just the 5 lug..

you could actually use his, and press the hub assy onto it off of yours.. but i would do both sides if I did this..

 

trailing arms are identical. What is diffrent is the spindle on the trailing arm. Sad thing is that you cannot get the spindle at the dealer by it self. I just when through this last week when a brakeline poped and my car spun and hit a curb bending the back left wheel. I paid 274 for the trailing arm with the spindle at the dealer since you cannot go to the junk yard to get an itr part.

Im pretty sure my spindle is fine, so I could take it off and use it on any trailing arm is what you are saying? Or are you saying I am I going to have to buy a new trailing arm+ a new spindle?

Thanks for the responses guys

This is in an EK, apparently.
When you went to a 5-lug, which rear lower control arms (and shocks) did you originally use?
From what I understand the ITR and GSR control arms differ mostly in the manner in which the shocks attach thereto.

 

Everything off the ITR was used for the conversion, so that would include the rear trailing arms.

I think I am just gonna eat the 200$ or whatever it is going to cost to buy the ITR trailing arm, it seems that no one is quite sure whether or not it will work or not, and I def. dont have time to tear everything down and find out the part doesnt work ( daily driver )
Plus I guess I could always hit up Len and see what kind of hook up he can get me

 

I'm pretty sure they are the same except for the hub... well I am going to try it anyways cause mine is bent. Mstewar, what are the other differences then?

Damn, yours looks a lot worse than mine
When do you plan on trying to fix it? Let me know if it works

 

what the other guy said was right about the lower control arm being diffrent, but we are not talking about the lower control arm, the trailing arm is identical. I just went to the dealer last week to fix mine and he explained to me that the spindle is the only diff. noe i would advise you not to put on your old spindle on the gsr trailing arm because your spindle could be bent. mine was and you could not even see it till you put it on.

 

The only difference I've seen between the two is the use of slightly stiffer bushings. The part numbers are different, but they will interchange.

Werd, thanks Len...Expect a call from me today, Ive got a few more parts I'd like to order as well

quoting this for sackdz's benefit.. bushings are different and the ITR one is a bit heavier(implying stiffer/more reinforced)..

ed, you did quite a number on that trailing arm.. when did that happen? are you trashing that one? if so, i could use the wheel studs..

 

The arm should be exactly the same, yes you could unbolt the spindle and put on the new arm but as they said up there, it could be damaged, i dont think i would risk it.

If you do go ahead just remember to get the right tools, those bolts are tight :-)

Aside from the bushings I mean... I'm replacing all suspension bushings in the car this winter anyway.

I've got both an ITR and a 4lug arm so I will compare on a scale and let you guys know about the weight.


That got bent when FLATOUTRACING's front left went all the way thru my rear tub and straight on into my right rear. The wheel and tire appear to be fine, as well as everything else, LCA etc, the trailing arm took it all, except for the trashed right rear tub of course. It was at MidOhio back in August.

Did somebody say you can get a 5lug spindle seperately? Am I gonna have to dissasemble the wheel bearing or drill out the hub to 5 lug?

 

Thanks for the help guys, I really appreciate it

You shouldnt have to drill anything, all you should have to do is :-

1. Undo the big nut holding the hub/bearing assembly &gt; Pull

2. Unbolt the 4 nuts holding the spindle assembly to busted trailing arm

3. Put everything back onto your new trailing arm in reverse order.

I think unless I have mistaken your question.

IF you are intending to use the 4 lug trailing arm AND its spindle it shouldnt be a problem as long as spindle is the same size( I dont know) in fact it would be easier cos all you would have to do is take off your hub from your damaged assembly and put it onto your new arm with spindle.



-------------------------

Actually i have just realised what you mean - you mean drill the 4lug hub to become 5? no dont do that, you can just buy the hub, it comes with bearing as one piece from Honda so simply put on the spindle, dont mess about with the bearing.

Sorry about the long post, its nearly home time in the UK and my head is dead :-)

funny thing is, when i bought a new left rear trailing arm for my itr suspension, it was like 30-40 cheaper than the gsr/ls.... etc etc... quite interesting

the spindle will accept the ITR hub, it has a little less length tho thread the nut onto but it will go on. however the ITR caliper bracket will not fit on the spindle, if you are in a pnch you can cut from the outside of the spinlde toward the mounting holes at a diagonal (the O shape made by the holes will now be a C shape) then you can mount the bracket.
better to swap the spindle if you've got it

I just ordered my ITR trailing arm, 185$ ...but better than full price
Big ups to Len for the hook up
