Jjr Upper Camber Arms

[Richo]

Just looking for some adjustable camber arms for my R32 and JJR has these ones +/-4 deg. and wondering if anyone here has had them installed, and what you think of them.

Do they really have the 4 deg adjustment? any major dramas with them?

Please write about own experiences if possible, avoid the " I've heard that a mate of a mate....."

Cheers

yup i bought a set, installed them in the car, drove around the block and then jacked car up to double check tightness of everything and what do ya know... BOTH arms had cracked their welds.

demanded my money back and vowed never ever to buy another just jap product

[Beer Baron]

which ones are we talking about? the dog-bone shaped ones?

If it is those ones I have a set in my car. as far as the adjustment goes I could only get a max of 2 degrees or thereabouts. this is because after they are screwed in a bit the two halves touch each other inside the turnbuckle. if you cut down those threaded sections you could get more adjustment.

they haven't failed me in any way, but after 1 trackday and about 150kms of driving they started squeaking like crazy. haven't been able to cure it yet.

these are the culprits that cracked i beleive

ahh, mine are completely different to those ones which is why I asked. those are rears I believe. I was talking about some fronts.

i'm talking about these ones:

[Richo]

Yes these are the ones, Front ones.

Are you serious Simon? thats not good at all, did you get any explanation from JJR as to why they could have cracked? installation or something?

How about some Noltec ones anyone tried this ones, how much adjustment can you get?

Cheers

They have a very similar design to the ones i got from japan, except mine are symmetric. i.e. the threaded parts dont have 1 longer than the other. Seems to me like it would be more hassle to do this... 3 different parts instead of 2 different parts

Looking at the Noltec catalogue, adjustment is via the 2 parts of the arm sliding inside each other and then are locked with grub screws (think camber tops, that style of sliding and locking).

These designs are known for slipping when used for control arms. They also retail for $691.43 according to their site...

Have you thought about just getting camber adjustable bushes? These are under $200, last time I looked (a while ago) they were being redeveloped to stop the excessive wear of one of the bushes and they were also coming down in price. They have now come down to $187 (i think) so I assume they are now stiffer and last longer?

[Beer Baron]

yes, i considered the noltel arms, but just couldn't see all those little cap screws holding the thing together.

the JJR ones I have a 'inspired' by the midori made upper arms. they are a good design. just need a little tweaking imo.

[Richo]

yes thats what i thought about that type of fasteners (noltec), under high stress it would be easy for them to slide or come loose. no good.

With the bushes.. how much adjustment can you really get?

First off have a read of this thread;

http://www.skylinesaustralia.com/forums/in...mp;hl=spherical

Keep in mind that almost all of the “retail” camber kits are designed to REMOVE the negative camber that occurs when Skylines are lowered. This is because the “road car market” is far larger than the “race car market” and they are looking at excessive inside tyre wear as the major problem that they need to overcome by adjusting the camber.

Keeping that in mind, the standard R32 style upper control arm is 190 mm long, centre of the outer bolt to the centre of the inner bolt. Using the off the shelf adjustable, offset, outer bush (Whiteline etc) reduces that to 184 mm. This gives around 2 to 2.5 degrees of negative camber on an R32 with a ride height around 355 mm centre of wheel to guard with around 6.5 degrees of caster on a 2wd and 5.0 degrees on a 4wd.

That is usually enough camber/caster, provided sufficient anti roll is used (larger stabiliser bars), for most circuits. High speed circuits with long sweeping radius curves (eg; Philip Island) need slightly more camber.

So we use the off the shelf adjustable, offset bush (Whiteline etc) in the inner of the upper control arm. That reduces the length to around 180 mm. This gives around 3.0 to 3.5 degrees of negative camber on an R32 with a ride height around 355 mm centre of wheel to guard with around 6.5 degrees of caster on a 2wd and 5.0 degrees on a 4wd.

This 180 mm length seems to have been the minimum that ALL of the R32 camber adjusters have been made to. All of the brands of upper control arms that I have measured (Noltec, Nismo, Ikeya etc) all stop at 180 mm or longer. So choosing one brand over another to get more negative camber is pretty much a waste of time.

Hi,

Just got these installed on my car, as Beer Baron says u can only get max -2degree adjustment out of them.

When i was deciding between the noltec one and the jjr one it was a fairly easy choice.

You should have a read of SydneyKid's thread on upper arms, very informative read.

Hope that helps.

Woops, too slow in my reply.

Well, that answers all my questions indeed, i will be installing a whiteline camber kit for the front

Thanks all!

[willowdrift]

Ive got an r32 gtst 4 door which I use for drifting. It came over from Japan with solid one piece non adjustable JIC camber arms which I beleive do the job great. They give around -5deg. They are cheap and strong.

[Richo]

So they stay at -5 degrees all the time? you must go through so many front tyres with that camber.

When you say cheap, cheap to buy here? where? wouldnt mind having a look.

[willowdrift]

Yeah they stay at -5 all the time. Pictures of my car sideways shows the outside tyre flat on the road so this is good.

Drift events in wa are months apart so ive been using standard arms for daily driving inbetween then come drift time I fit the JIC's (which takes me 45mins). It looks like garage-13.com are selling these arms from $175.

[Richo]

Willow.... Do garage-13 have a website? thats cheap as!

SK....was jsut having a look at the whiteline catalogue for these camber kits which is the part number im looking for? the only one they seem to have is only +/-0.5 deg. which seems extremely low adjustment, any help would be appreciated.

Cheers

Ric

[willowdrift]

Its in my post Richo except the www. bit. anyways its www.garage-13.com

[Richo]

oh yeah, found it!! they look allright, I think you have to order them in though. 4-6 weeks wait

What camber does it have with the standard arms fitted?

there pieces of crap. max adjustment is less then what you can get with ofset bushes

the same go's for the radiouse rods
