I bought a set a while back, just the trailing arms w/spindle. No hubs. Are there any distinguishing markings that confirm they are from a Type R and not a GSR, LS, etc.?

-Ken

 

Not that I recall but regardless, they are all the same (however, part numbers say otherwise)

 

So the only differences would be hubs (4-lug vs. 5-lug), and calipers??

 

Just the hub.

 

So if you bought a 5 lug hub from acura it would bolt on to the trailing arm?

This being true you should be able to buy type r rotors, and use the fast brakes 11 inch rear upgrade w/gsr calipers. This would give you 5 lug without buying the whole trailing arm.

 

I believe that there are differences in the durometer ratings between the ITR and the GSR/LS T/A bushings.

 

is there any way to confirm this?

No one seems to have any solid answers. Someone has to know.

Is there any body out there that has installed itr rear hubs onto gsr/ls trailing arms?

 

yes it will work. btw not all itr trailing arms are the same. jdm 98 spec itr trailing arms have a reinforcement plate behind the trailing arm bushing

In regards to USDM vehicles, they're all the same. The only reason we have a Part Number difference is the different bushings used.

So not to sound redundnt.......but this means that you could use us itr rear hubs on gsr rear trailing arms and it will bolt right up.

After doing this one could bolt bolt up itr rotors and calipers and have 5 lug with no question about wich rotors or pads or calipers to use?

This is true. We have a very basic 5-Lug conversion kit for those who are interested in Brand New OEM Parts and the rear consist of the hub/bearing assembly for both sides and brake calipers. Rotors and pads are sourced separately.

Where do I get this and how much?

 

I second this. I looked at their site, but it's just a general Acura-parts site; there's no obvious place where any special packages like this are sold.

I took a quick look and the front hubs are $100 each and the rear ones $140 each, for a total of $480 just for the hubs. I don't know if other parts are needed (probably).

 

the ITR spindle is about 10mm wider than a GSR. the spindle nut will only bolt in part way if you use the ITR hub on a GSR trailing arm...

This is true! When I worked at Hasport, we tried to put rear Type R hubs on a 4 door GSR's trailing arm. The nut only engaged about 4-5 threads. I wouldn't want to drive on that setup since it only had about 4-5 threads holding it on, especially at high speeds on the track!

 

Ok, I'm confused. Up above, they're saying the trailing arms are exactly the same, except for the bushings being harder. Now you guys are saying you can't interchange them. Which is it, or am I missing something important?

 

can the spindle not be replaced as well..?

Pics are sourced from hondaautomotiveparts.com and used as just a reference.
part #2 this is the piece u could technically swap over to any rear disc integra and convert to 5 lug but like it was stated just above u will not have enough threads sticking out to securely bolt part #2 because the itr spindle is 10mm wider than gsr. hth

 

in this pic u can see the trailing arm and the hub (that is what sticks out and the spindle, part #2 on previous pic spins on) The best way is to switch the whole hub with the spindle and all still bolted together. U can unbolt the complete hub assembly from the trailing arm with 4 or 5 torque head bolts and one big nut.

doing it this way allows u to use any trailing arm u want. I have an eg with DA trailing arms with my itr hubs bolted to those so I can get extra rear track. I figure I have about an extra 8mm of track in the back. hope I cleared it up some if not pm me

 

exactly.. I guess the tough part for people trying to do this is that you can't buy the spindle portion without the entire trailing arm from honda..

 

Ok, I understand now. Thanks for clearing that up.

I wonder if it's possible to buy just the spindles somewhere else; do they sell remanufactured ones? Or are there any other Hondas with the same spindle? Perhaps the parts for another model Honda would be cheaper from the junkyard than from an ITR, which is relatively rare.

 

Ok some people say only the hubs are different.

Some people say the spindles are different.

The Helms manual says only the front track on the R is wider 5MM/2.5 on each side.
According to Helms the Front Track Is GSR:1,475MM R:1,480MM
Rear Track Is GSR:1,470MM R:1,470MM

So The big question still remains.....Will swapping just the rear hubs work??????

Does anybody know for a FACT!

I, among many others really, really want to know!

I'd trust what Len is saying, but I really don't know. I wish I'd payed closer attention when i had both laying side by side.

To end this, I will order both the GSR trailing arm and Type R trailing arm and take all the measurements and document all the difference with pictures and data.

How's that sound?
