well, further developments have occured....which I will post on a bit later, but for now, I have one question that despite searching forums and manuals I cannot find the answer: What is the standard/stock/factory ride height (centre of wheel to guard) on the R32 gtr?

Thanks,

Fraser.

395 mm front and 390 mm rear, brand new. They settle around 5 mm until 60,000 k's then the front standard shocks are stuffed and the front springs wear out real fast. It's not unusual to see them with standard springs at 370/360 mm.

V Spec & N1 is 10 mm lower, ie 385/380 mm, new.

Cheers

Gary, thank you so much. That puts a whole new context to things. My car is 75mm lower at the front than stock and 55mm lower at the rear.... no wonder I can't get enough castor on the front left to stop it pulling to the left.....no wonder the ride is tiring...etc....

based on this wonderful bit of news, i might be able to get the results i'm after without having to get custom made springs..... back to the calculator....

Thanks,

Fraser.

well, after doing some more sums, I believe I can get close to the ride height I want by using Kings Low springs or Tein STech Springs.

So, over the weekend I have put the car up on stands and taken out the springs/shocks.

Tomorrow they are going to Fulcrum so they can:

- remove the springs from the shocks,

- dyno the shocks to make sure they are ok(hope so), if not i will have them valved for the new springs..

- then fit new springs to the shocks for me.

Which I will then refit to the car then get a 4 wheel alignment.

So what springs I hear you ask? Well, Tein Stech in the front at 3.7kg/mm and King Springs Low at the rear (2.7kg/mm). (57.8/0.422)

I know the STechs only come in sets of four, but I could install in the rear if I want to play with the handling, or i can sell the rears...

hopefully there are no problems reinstalling and the money I saved removing the struts covers the cost of the extra pair of springs.

Will report on progress.....

Fraser.

Disclaimer: this is not meant to be a bashing post.

ok, update: saturday 3 weeks ago i purchased some car stands (repco $30 a pair) and within 2 hours had the shocks and spring out of the car.

The following tuesday I delivered them to fulcrum.

They removed the springs then dyno tested the shocks.

On thursday I rang to find out progress. The shocks tested up well. (woohoo $150 a corner saved), they had ordered the Kings for the rear but were having trouble finding a set of teins for the front.....but they could get some in from Japan....

First Mistake: I assumed that Fulcrum (the Aussie Tein R&D partner) would have stock....

So frustratedly(and smart-arsedly), I suggested an ebay auction that Fulcrum could purchase the springs from, they informed me that they couldnt, but that I was welcome to purchase and have Fulcrum fit to the shocks for me.

So I purchased from Access Autoworks. They were good. Paypal was not. No matter what I tried, the only way I couldve had the springs shipped direct to Fulcrum would have been to change my primary home address to Fulcrums!

So with a couple of attempts, I finally got the Teins shipped....to my home address.....which meant they would end up at the post office for collection.

Last Saturday I walked(remember car is still up on stands) to the Post office and picked up the springs, took them out of the box to put them in my backpack to bring them home.

Second Mistake: Dont use paypal if you want to ship to a third party

There was also a japanese instruction sheet in the box which I did not read until I got home.

I got home and read it. It said: Front 3.7kg/mm check, Rear: 2.0 - 4.0kg/mm ARRRRGGGGHHHHH!!!!

ALL the data I had looked at said Rear:4.0kg/mm ... which is why I bought a set of Kings for the rear!

Not even Fulcrum when I said 'I just cannot believe that the rears would be stiffer than the fronts' had nothing.

Third Mistake: dont trust the manufacturers or distrubitors websites......

So, I am continuing with the Kings in the rear as they are already fitting to the shocks. On Thursday, I will deliver the front springs to Fulcrum.

I did want to share the rant, thanks for reading but I mostly wanted to share:

Tein S-Tech Springs SKN14-S1B00 for BNR32 Spring Rates: Front: 3.7kg/mm, Rear: 2 - 4kg/mm. Which gives 65/35 ratio using 2kg/mm at the rear which is what I was trying to achieve from the outset!!!!!

perhaps I will swap the kings rears for the tein rears.....anyone want to buy a set on kings rear springs? never used!

Thanks for reading, hopefully will refit everything this week.......

Fraser.

OK Gary "SK"

With your spec. Bilsteins,

For Street, Kings low vs Tein S-tech vs Eibach Adj.

What would be your choice?

Is there a difference between hot vs cold wound coils?

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
