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.

The problem is the alignment of the inner and out joints. There is the stagger as you have mentioned, plus there is also the question as to whether or not they would be better (wear the bushes/joints less) if they weren't in fact parrallel.

As for making your own arms, we aren't allowed to do that in Production or Improved Production Car racing, so it's not something I have ever contemplated. Personally (if I had no restrictions), I would simply ditch the R32 uprights and upper control arms and use the R33/34 equivalents. The wide spaced upper "wishbone" is a far superior design compared to the simple "I" beam used on R32's. All you would need to do is to remove the R32 brackets and weld on the R33/34 style, then bolt up the arms. Much easier than making arms from scratch that are always going to be compromised in function by the over all design. By selecting the appropriate locations for the brackets you can tailor the camber curves. In fact you could make the curves adjustable by having multiple location holes.

Rotating them did occur to me. I guess if you rotate them by the same amount as the difference between stock castor & however much castor you run it would be about right. Ofcourse it makes the fabrication that much harder - probably too hard really. Square is easy, parallel is easy, off by a couple of degrees gets hard to replicate.

yeah the later ones are nice, i half finished fitting a combination of GTst brackets and arms (but using the GTR uprights due to improved bolt in alignment) to my 180sx project and have put it on hold to fit up the later setup, sick and tired of uncle mac in s series cars.. we will see if it is worthwhile.. if not ive only wasted a few hours and some mig wire :domokun:

I found this in my travels:

Specifically the upper link bracket and the transverse link are interesting. Shame there is no really specific dimensional info offered, although some lengths etc are quoted.

I've been in contact with UAS in regard to the adjustable upper arms for the 32....

Currently UAS are negotiating a big batch for sale. No date but stay tuned.

In the mean time I'm going with the "double" KCA336 kit concept as discussed in post 17 by SK

Ok finally got an alignment. With the Drift Shop, Midori style, I went from -0.5 to -2 before I ran out of adjustment. So Around 1.5 degrees I got. I would guestimate I could have done about the same distance in the positive direction, so a total adjustment of around 3 degrees is my (educated) guess.

hi all

have been researching how to get some camber adjustment on my R33

and have come across these arms on ebay

they just dont look like R33 items althought it states they are ?

does any one know what they are ? if pic works

They look to be a 2 piece arm, in comparison to the standard upper control arm which is one piece. One arm bolts to each side of the upright (hub), then bolts to the inner pivot points on the standard brackets. The trick would be to adjust the pair of arms in tandem, otherwise you will screw up the caster and most likely the bump steer.

I would strongly suggest that adjustable bushes are a better proposition, unless you need gross amounts of camber correction ($183 on the Group Buy).

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
