R34 GTR suspension settings?

[No Crust Racing]

Aligner is telling me if I can grab some castor arms before coming in that would be good as they're not adjustable factory and tend to pull left because they're a bit shorter one side from factory so they will pull left naturally. 

Any truth in that?

roads are not flat so it will pull the the left if it has factory castor

I didn't think there was any adjustment in factory castor arms?

No - as Andrew points out it will pull left because of the camber of the road surface - he is referring to factory castor settings not arms. That's why SK suggests giving the LH an extra 1/4 degree of castor.

So are the factory arms adjustable? Offset bush or something?

EDIT: Just looking at pics of the LCA, didn't realise it was all one unit including castor with no adjustment essentially.

Given ride height of the car (even with it on max height as the BCs are just a low coilover) and all factory arms there was only so much that could be done. Car is driving straighter now though. 

Ended up with roughly:

Front:

Camber: Approx -1.5ish both sides

Toe: Approx 1mm toe out both sides

Caster was around 3.5-4 both sides, no adjustment in that factory, need to do the R33 conversion with separate arms. 

Rear: 
Camber: Approx -2 both sides.

Toe: approx 1mm toe in both sides.

See how it goes.

Not bad, would have toed in a little more at the rear if you plan on tracking it but it does smash tyres unfortunately.

 

oh look, I drove your car around Hakone and Mazda Turnpike in November when in Japan haha.

Man the stock R34 GTR was so slooowwwwwwwww, lag, transient response sucked balls.

 

[No Crust Racing]

I've never seen/been in a stock one. Can't imagine it would excite me much. 

[Hadouken]

I've driven stock. A golf gti is quicker.

[elChin0]

Its not that bad  lol

[No Crust Racing]

I'm sure it was zippy for the era, but times have moved on. A Focus RS now has like 270kw 0_0

[elChin0]

The truth hurts lol .. fortunately (or unfortunately, depends how you look at it) my first car was an NA 34 so this is quite the upgrade.

...for now. Lets see how long i last stock 

[No Crust Racing]

Yeah it's all a matter of perspective and what you're comparing too. 

Dumps, exhaust, panel filter, and a tune will make a big difference without breaking the bank.

The lower output lets you savor the revs more in my opinion, i went from 270wkw relatively stock to 320wkw and yes it's quicker, but 270 with stock turbos and exhaust is plenty enough car to enjoy on the street without having to hang on for dear life/licence.

I think the big difference is response. 250-270kw is quite responsive. 350+ not so much on a little 2.6L

The stock R34 GTR was aids.. 1 bar by like 3600rpm.

I can't imagine bigger twins.. oh wait I can, drove Piggaz' car with the GTRS back like 10 years ago.. was aids lololol

Track day has been done, car was quite prone to understeer and had bulk rear grip. Needed more front camber and not to be running 400 treadwear tyres, yes I said 400 lol

Lots of tyre squeel.

3 deg front camber seems ideal for track but will be a pain on the road. Cusco camber arms are quality. Have you upgraded your rear sway bar? That should help with understeer.

[No Crust Racing]

Rear is whiteline, front is standard.

I wont be tracking it again.

Can't enjoy fast cars on the road
