Went to order a set of the Noltec front upper camber adjustable arms for my 32 gtr today, and have been told they have been discontinued... now I'm looking at the Silk Road front camber arms as they seem to be of the same design/principle... has anyone bought these? or seen them in the flesh? just trying to gauge adjustability/reliability I guess...

I've also looked at the Midori front upper links but I'm not too keen on paying $650+ when the Silk Road arms are ~$350.

well they are chinese made (section/silk road) so i would not want to pay too much more than 350, the midori ones are made in japan and were copied by many like KTS (also taiwan) etc.

if your happy with the silk road ones check out driftshop.com.au and ask costa if he has his version in stock... im sure they would be the same thing and as far as cheap arms go his are the better of what is available here. I ve used his stuff a bit when in a bind and it has alsways been better than the other generic stuff.

They are a bitch to adjust, you can't get to the locking nut while the arm is connected. You will pay more for every wheel alignment as a result.

are the driftshop ones you mentioned URAS?

SK, have you seen these used? I know you aren't a fan of having everythign so solid...

Haven't seen them in use as yet, won't be long though, without dust seals and grease retention they won't last very long. So I will have guys PM'ing me for advice on how to stop the knocking.

Hard to tell exactly from the pictures, but their minimum length looks too long for sufficient negative camber on the high speed tracks (eg; Philip Island)

Cheers

Gary

yeah making the lower arm longer is a good thing. gives you more track as well as the camber you need. the only reason people don't do it more often is the cost. typically the lower arms cost more than double the uppers.

Plus it always screws up the bump steer something fierce, often changes the Ackerman and does no good at all for the dynamic camber change. If you fix those things then, yep, longer lower control arms work fine.

Cheers

Gary

Yeh, not sure what it does to bump steer but assumed it woudl be bad for ackerman.

Im slowly learning with cars. Keepign it simple means the best results. To get stupidly good results you either need to own a GTR and have a workshop that has done all the R&D or wear the cost yourself. Stick with the Noltec arms, or speak to UAS about his replacement arms that he is bringing to market very soon, they look to be good things for the R32/Z32 range that can chew bushes when you run too much camber abd castor

Can't help you with if they are any good - But where are you getting them from at that price?

I went ahead and got the Section arms, they are made rather well but I can see what SK means by being a bitch to adjust, you basically have to pull them out, reset, and put back in, I installed them on their lowest camber setting (pulled all the way in), and I didnt get much negative camber at all... :blink:

Would it be super dodgey to slot the mounts? :thumbsup:

....speak to UAS about his replacement arms that he is bringing to market very soon...
I sent off an e-mail to UAS.

Checked my mail today and recieved an e-mail on from UAS on Monday, "...waiting to get an eta but suspect next month and they are the best on the market and unique in design"

Stay tuned

Haven't seen them in use as yet, won't be long though, without dust seals and grease retention they won't last very long.

two years no greasing with regular checks (i would suggest checking after a trip into the sand traps though :) ) and still going strong with nil play..... these are used in most of japans fastest super lap cars.

Far more than just cheap chinese arms, most have rc + bs correction and so forth in built.

Most 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. For reference, the standard R32 style upper control arm is ~180 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 ~175 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 170 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 170 mm length seems to have been the minimum that ALL of the R32 camber adjusters have been made to. Of all of the brands of upper control arms that I have measured (Noltec, Nismo, Ikeya etc) the minimum is 172 mm. many are longer. So choosing one brand over another to get more negative camber is pretty much a waste of time.

Keep in mind that when you add caster, the R32 designed upper control arm has no choice but to distort the bushes. Hence they become a consumable item, you simply have to change them regularly. Just like brake pads, the bushes wear out and need replacement. This is why Nissan changed the design of the front upper control arm on 33's and 34's.

You can't easily slot the outer holes due to the design of the upright (hub). If you slot the inner holes enough to make a worthwhile difference, the arm rubs on the inner guard.

Gary,

Here is the Cusco fixed arm I just bought. (Thanks Tacker :)) Centre distances are 172mm. Unusually they use a common bearing: 6203Z if anyone cares. I was going to knock those out & replace them with some bushes.

Also of note is the amount of stagger, ie how far the inside is behind the outside is 23mm. Not sure if adjusting this would help generate more castor without negative side effects.

Gary,

I think you may have confused the stock length with the adjusted length. From memory the stockers are 182 centre to centre.

Thanks, I should learn to never rely on my failing memory, post amended accordingly.

Cheers

Gar

Random question:

You can move the bottom of the upright forward for more castor. But given the arm has stagger built in, can you move the top further back? That assumes you fab up your own arms - which isn't hard looking at the Cusco ones.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
