Is There A Problem With Whiteline Kit Kca336?

[djr81]

Yep, I just rang Repco (listed as the vendor on the Noltec website). Got the usual answer: Nup, never heard of them.

I've seen a couple of sets of the noltec ones (non-adjustable) and was also wondering about whether the extra collar helps with the durability - is anyone running them with big caster?

What we really need is upper arms designed with the extra caster in mind......*squints at gary*

A friend had the Nismo arms in the front of his R33 GTS25T. They werent adjusable but they were meant to be aligned for better traction at a lowered ride height. Having driven the car at Wakefield and EC it was a sensation compared to the handlign of my car.

So the Nismo arms for the GTR/GTST, do they solve/allow for this problem?

Otherwise, if i can get my hands on Visual Nastran then i can model it all in 3D and do the motion analysis on it to get some fixed length arms made up

[djr81]

The model would be great, but effectively the Whiteline kit makes the arm a fixed length - just shorter. I think what it needs it a slight twist in it so that the caster induced load in compression that occurs on the upper link bushes is reduced.

But without the model that is just supposition....

[Beer Baron]

yeah, that's why i used the dog bone style ones as you can introduce a twist on any angle you want.

I could get noltec ones with about 40% off the rrp, if we have enough buyers, but im dreading starting another gb.....

[djr81]

I doubt you would get a sheet load of people wanting them. They don't do anything other than repalce the standard ones & are non adjustable. The Whiteline gear is adjustable & for most uses appears to be fine.

I am looking for a set, however...

The R32 Nismo arms (I actually have a set) are EXACTLY the same as the standard arms, except they had “hardness up” rubber bushes. I haven’t ever seen a set of R33/34 Nismo arms, so I can’t speak for them.

LOL...really? You forget they are painted silver and have Nismo stickers on them!

Oh well...im worried about takign the car back out with eh clunkign on the front end. horrible noise and is pretty disconcerning. Sounds like im going to damage somehting big time

I just hope it sounds worse then it is

[djr81]

So that would price the silver paint at, what, about $130?

Got the Noltec bushes delivered. For once they cost less than listed price. $120 ish with postage. For the record they feel harder than the Whiteline bushes, despite all the palaver on the Noltec site.

Sydneykid,

Slightly old thread but, Very interesting. How are you going with the upgraded camber kit for R32's? Any news regarding them yet?

My road going gtr needs either new upper arms or a better bush style camber kit installed compaired to the Whiteline kit currently available. All products using sealed bearings like Midori and Nolathane arms are designed for track use only and are too harsh for street driven cars and illegal.

Love to get my hands on these Gary

The issue with R32’s chewing out bushes in the front upper control arms is a known problem, hence why Nissan changed to the wide spaced inner pivot joints on R33’s and R34’s.

As a few of you know, I am currently testing a revised camber kit for the front of R32’s. The revision is to allow more camber adjustment by utilising an offset crush tube in both the inner and outer joints. The normal camber kit only has an offset crush tube on the outer joint.

As well as allowing more camber adjustment, less negative camber for excessively lowered road cars and more for circuit cars, it will add more compliance into the upper arm inner pivot joints. This should noticeably decrease the propensity for the (current) low compliance inner bush to be chewed out by the distortion caused by the R32 geometry. Which (as a couple of you have found out) is exacerbated by increased camber and (mostly) caster.

The off the shelf KCA336 kit contains both alloy and poly bushes for use in the inner pivot point, refer picture following;

What I am testing uses full polyurethane bushes (no alloy) in the inner pivot point,.with an offset crush tube for adjustment This will allow capacity for more of the inbuilt distortion (on suspension movement) to be absorbed by the thicker shanking on the bush. Following is a picture of a Nismo upper control arm with the adjustable bushes installed in the inner and outer joints.

I have only just started road testing, so it is early days yet. I will also be carrying out some circuit testing in the R32GTST. If it stands up to that punishment then I will be offering the upgrade for those that want/need it. More updates will be posted as they occur.

cheers

PS; it is worth mentioning at this time that the Group Buy price on the KCA336 (for R32’s) and KCA348 (for R33’s, R34’s and Stageas) has been reduced from $272 to $183. This maintains the 15% discount on the Whiteline retail price (20% if the order is over $1K).
