Default 98 Spec Rear Upper Arms

Hey guys,

My car is all stock suspension wise, but would putting in the 98 Spec tubular style rear camber arm make any difference? Ive done a search and found conflicting reports regarding camber changes and stiffer bushings, just wanted to see who had real world experience on the street and track with these items

Didnt really notice any difference, but the design is a lot stiffer, so the lack of flex under load is only a good thing IMO.

UCA Flex? Really?

I know nothing about how the rear suspension really work, under load! So I take your point!

But my point was, anything that seems to resist flex is surely better than those which do? After all why did Honda revise them for the 98spec.

Happy to listen to any other input

Iv read somewhere it increases camber or had something to do with camber. Would like to know as well just for knowing purposes.

If you change them, you will feel a huge improvement initially, but most of the effects will go away after the break in period of the bushings. At least that's what I felt when I changed to the 98 UCAs.

the tubular rear upper arm is designed to clear the JDM 16" ITR wheel.

the USDM version hits the inner barrel/lip of the wheel.

Oh really? Is that only if I'm lowered or will it be a problem with stock suspension? I havent heard or felt any contact, but I'm worried now that I'll scrape up the inner lip of my wheels if I lift a rear wheel on the autocross while cornering..

It was a problem on stock ITR suspension and 16" jdm ITR wheels.

Not sure if its a problem with lowered cars and aftermarket wheels though.

Wheels contacted on the hoist when we put them on car. We were like, "wtf is hitting?!?!" Lol

If it doesn't contact the arm when the car is stationary, lifting a wheel autocrossing shouldn't be a problem either.

<--- has 15x8's that just barely touch the stock UCA. You could tell they were contacting it as soon as the wheel was mounted.

Don't forget the jdm "36mm" suspension is also 5mm wider then the usdm. Moves the wheel 5mm farther away from the rear upper control arm.

** may have been 3mm, been a few years.

^^^ I think your comment is partially correct... ALL ITR rear trailing arms are 5mm wider on each side over the standard tracking of the Integra.

I suggest you research some more if you think I am not 100% right. The rear spindle is different.
