I have needed more negative camber for a while now. Not keen on bushes so im interested to hear from anyone who has used either of the following:

http://www.rhdjapan.com/ikeya-formula-fron...et-nissan-51469

http://www.rhdjapan.com/cusco-negative-cam...34-wgnc34-16650

The Ikeya arms look strange to me in that they are two piece. As far as I understand both Ikeya and Cusco replace the upper control arm that bolts to the body of the car... the standard one is once piece.

With that in mind, it looks as though the Cusco item is easier to adjust but at the expense of fine adjustment. Cusco also seems like it would be stronger being one peice. Do I have it all wrong?

How much camber adjustment do the two sets provide?

How much camber do you have now? What are you doing with the car?

Car is approx 1 inch lower than standard, 1.6deg/1.9deg last I checked (saggy stock bushes hence the different side to side).

Need more front end grip and as a side benefit, even tyre wear. Chews the outside of the front tyres. Have a new set of tyres that are less than 5000kms old and the outside is already getting destroyed so I figured it was a good time to run some serious camber and even it out :banana:

Well it begs the question: For you how much is serious camber?

I dont have experience with camber on other R33s so I cant say for sure. From what I have seen, running the tyres I have now I would guess 2.5-3 degrees on street and 3.5 on track.

I wont know for sure until I try.

Does anyone have an idea of how much adjustment those arms can provide?

Thanks Ryan - I find your arms confusing in relation to the Ikeya/Cusco types.

Is there only one piece per arm? From the web site photo they look like part of the Ikeya set. Is the picture wrong and they come with the curved and straight arms for each side or are they only the curved piece? Is the end that is bolted to the chassis rubber bushed?

cusco will give you -2.5deg with a ~340mm center to guard, add in a offset bush and you will see -3deg.

i run the cusco, once piece makes it easy and without a threaded piece, pretty much maintain free.

Those are 2-3 times the price of the others, I dont see the advantage, how are they better than the Cusco or Ikeya ones I posted pictures of?

Thanks, however that seems a bit strange to me..im pretty sure I run approx 340mm center to guard (thats 1 inch low isnt it?) and assuming you have over 1.5deg neg already, that means the Cusco arms are only giving you -1degree extra, is that correct? On the max neg setting?

Before you waste your money figure out how much camber you actually need. I would try offset bushes and if you still want more re-drill the standard upper arm.

Im 100% sure -0.5deg extra will not be enough, plus the whiteline bushes retail at $192. I would rather spend $450 on arms that give me easier/more adjustment and get the bushes if I really need.

Never considered re drilling the standard arms, have you done it or have pictures of a redrilled arm? How much extra camber can you get this way?

I have heard from another source that the Cusco arms provide ~1deg of neg camber as ssxRicho reported.

So how do others get more camber? Surely race GTRs dont get by with bush + adjustable arm (-3deg).

The only other ways seem to be re drilling the standard upper control arm or using aftermarket lower control arms as well. How are people doing it?

How? By running a longer LCA, a shorter UCA with the addition of bushes.

Yes but I am interested in how to do it in a practical sense. Do you mean custom upper and lower arms or off the shelf? If off the shelf, which ones, and if custom what have you done ie shortened the arm or re drilled etc..

More detail would be much appreciated.

just to compare at the same height with the offset bush at maximum is was getting -2deg. add the arms in at max neg setting

and adjust the bush for -3deg. the bush is not maxed out, but wont give much more anyway.

a mate also has an ecr33 and cusco arms, but with the oem bush. on max setting he is on -2.5deg.

there are 3-4 settings on the cusco arm, depending on the arm.

i think you will find 'track' cars modify the lower arm and weld up a rose joint or the like to push out

a wider track and get more camber. there are a couple of pics floating around, if you look

in the fatz goes racing thread in build ups maybe, i think.

Thanks mate. Im going with the easy option as to not risk messing up the geometry with custom arms since I dont have the patience to get it right. I found a couple of pics as you said.

Im getting a price on the Cusco arms with the 4 settings and will probably go with the Whiteline Plus UCA bushes.

Did you find any issues fitting the adjustable bush in conjunction with the Cusco arm? Looks like you cant use the bolt that goes through the bush which comes with the cusco arm, instead the two bolts that come with the kit, seems dodgy:

I just ordered the cusco upper arms from japan $400. I'm assuming they are the 4 settings item.

Theyre an awesome piece of kit. I run them in my 34.

3 point adjustment. I run my car pretty low (tyre flush with guard, but I have -3.5 front camber on the car.

Ikeya are wicked but the price is quite a lot more.

Cusco all the way :/

Do you run them with aftermarket camber bushes in the upper arm as well or just the standard bush?

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
