On Friday I had a wheel alignment done on my R33 GTS-T Series II and I attempted to get it as close as possible to Sydneykid’s recommended settings.

I cannot believe how these changes could change the behaviour of my car so much. It went form a Tokyo Drift special (sideways more of the time than not) to something that is heaps faster because it just puts the power down and does not go into power oversteer all of the time.

In the wet in a straight line it again just puts the power down with no wheel spin where before if would break traction at 2600 rpm in first, second and third and this is with 18 x 8’s all around.

This has changed what was a drift pig in the wet to something that you can drive heaps faster and be in total control. The funny part of this is that I was just having a wheel alignment done to see how bad the current settings were as I was going to buy one of Sydneykid’s suspension Group Buys. If it is this good with the stock suspension adjusted as close to his settings as we could get – how good will it be with the Bilsteins, adjustable roll bars and adjustable bushes – I cannot wait.

Sydneykid you are a legend!!!

Sydneykid's Recomendations are:

Front Camber -1.00

Front Caster 7.00

SAI 9.00

Front Toe 0.00

Rear Camber -0.5

Rear Toe 2.00 mm in on each side

I was able to achieve with my stock suspension:

Front Camber -1.20

Front Caster 6.35

SAI 9.10

Front Toe 0.00

Rear Camber -0.20

Rear Toe 1.50 mm in on each side

These results are close to the recomendations and will require the adjustable bushes to get that last little bit. My ride heights are also close to the suggested levels of about 25mm lower than stock front ride height of 380mm with 365mm front and 355mm rear.

If you dont mind me asking a few n00b questions

what is SAI?

and how do you measure ride height? distance from what to what?

and if SK just happens to find this thread

Whats the reasoning for

0 toe in the front and 2.00mm at the rear?

oh and isnt toe usually measures in degrees?

Toe in at the rear will help with keeping the car direction stable and whilst cornering will help the turning. I believe toe out on the rear induces unstable directioning and helps the rear end oversteer. Does that make sense?

If SK answers it the response will be alot more informative for sure :laugh:

2. and how do you measure ride height? distance from what to what?

and if SK just happens to find this thread

Whats the reasoning for

3. 0 toe in the front and 2.00mm at the rear?

4. oh and isnt toe usually measures in degrees?

Suggestions follow;

1. Steering axis of inclination ie; the point around which the front wheel rotates when the steering wheel is turned.

2. Centre of wheel to guard, that way it doesn't matter what diameter wheels you have or what size tyres.

3. Toe out is a destabilising setting and toe in is a stabilising setting. So, zero toe on the front is nicely in the middle. It means the car reacts to steering inputs, but not viciously as it would with toe out. But not dull as it would with toe in.

The rear toe in is to stabiliser the rear under power, pull it straight instead of excessive oversteer

4. Not when I do a wheel alignment, distance is the go for toe.

Hopefully that should give you some indication as to why the recommended settings are what they are.

:D cheers :D

Wouldnt skylines benefit from a bit of a bit of negative toe in the front?

I find that the front heavy weight distribution of skylines, causes some pushing understeer on the entry of a corner depending on the radius of a corner, how bad depends on the quality and size of the tyres. so wouldnt negative toe help with this problem? Is there a downside from running a bit of negative toe? e.g. stability powering out of a corner

The recommended settings use extra positive caster to fix the corner entry undsteer problem. You could use toe out, but it can cause tramlining. So it's more of a last resort on a road car, for a track car we use whatever is necessary of course.

:blink: cheers :P

are the settings the same for Stageas, Gary?

got to install the front caster bushes and have a wheel alignment next month.

Hi Brendan, check the Stagea Group Buy thread for the recommended settings, the 4wd setting are different to the 2wd settings.

:( cheers :D

these settings good for a 32 aswell? Getting some stuff installed and possibly a wheel alignment on friday? Is it a waste of time getting a wheel alignment if the current 16's your using you plan to get rid of in favour for 17's?

Same settings for R32GTST, R33GTST and R34GTT (GTR's are different).

Wheel size (width or diameter) is irrelevant.

:mellow: cheers :rofl:

Check out the Group Buy thread for your model, the recommended alignment settings are in the blue box with the parts list.

:( cheers :(

i dont really understan about wheel alignment, anyway can i just give this data to someone e.g. donellans, and let them do it?

sorry about this silly question :D

Great thread!

Just wondering if these settings are for any R32gtst, or only ones with the extra mods (ie castor bushes)? Atm I have stock suspension with aftermarket shocks/springs. Will I feel any benefit getting a wheel alignment with the above settings?

Im very interested...

    • 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.
