Does anyone have a part number for the JDM 98 spec rear upper arms ? I've seen them on IPS etc but as I'm in the UK I'd like to see if my local honda dealer can get them.

 

I dont think I'm going to get very far with my quest for a JDM 98 spec chassis/VIN number so does anyone have the part numbers for the uprated tubular rear upper suspension arms fitted to the 98 spec. JDM R's? I can order them from suppliers in the US (I'm in the UK) but my dealer can get it for me if he has the part number.

 

The JDM pieces are tubular, but otherwise why do you really want them? They give you more negative rear camber, which usually isn't what a person wants as it promotes understeer.

You could always get a true camber kit for the rear so you can have some adjustibility.

But, IPS, R&D, AJ Racing, JDMspecperf, etc all have carried them at one time.

 

I know this has been covered before but in the BM 1 video "Mr Spoon say's" they are a good upgrade for a "96 Spec." car. They should cost around $22 a side which is less than most of the kit's I've seen.

Plus (hopfully) I can get them from 5 miles down the road not 5,000 miles across the atlantic

Is that right? I have both (USDM & JDM 98spec), and have measured the specs side by side. They share the exact dimension in length, which is what determines camber correct?

 

Sounds to me like the camber is the same.

The reason I'm getting them is that it keeps the camber consistent by avoiding any twist in the 96 spec part.

 

22 a side? Maybe in Japan. In the US I have seen used sets selling for 100 dollars.

I thought it would promote less understeer...

 

No, they are shorter from all of the measurements that I have seen, which will give you more rear camber.

And yes, more rear camber = more understeer. The more the rear end sticks to the ground, the more the car will push. But, it's a trade-off and suspension tuning is the key.

Do you have a part number ? My dealer is comming back the the 96 spec. part

 

Placed side to side they look to be exactly the same length.

Im interested in these measurements you have seen??

Yes please. It'll help when I'm trying to describe them to my dealer

 

i have a pair for sale.

 

I think I've finnaly found the part number for these with some help from DutchITR1689

The part is 52390-ST7-Z11 and you need two of them (that is there is only one part number).

I also found this showing the difference between the two.

I'll phone my honda dealer tomorrow and find out how much they are in europe.

 

"There is the feeling which has become feeling hard, but as for difference it is not understood excessively. Whether difference understands when and the like penetrating of the last corner of Tsukuba, the ‚µ‚ê‚Ü‚¹‚ñ. Next Tsukuba is the pleasure. "

LOL. I think I want it too.....

 

I got a pair of these from AJ racing when I poped over the Redmond WA in March. The arms are the same length exactly as the standard items the difference is the stiffness of the part. After having to cut one of the bolt's of that siezed I fitted both. The difference seems to be a more controlled ride over holes in road etc. The rear does'nt seem to crash about as much. The back end just feels more stable. The arms I removed were not worn much (&lt;30K miles) so I'm not sure how much of this could be atributed to the bushings on the newer part, not much I'd say....

 

For not a whole lot more you can go with this:

You are the only one that I've ever heard say that. Everyone else says that they are shorter.

 

they are the same length, i lined them up side by side to compare. guess that makes me number two
