sounds awesome in the vid!

Dave's inlet system at work there.

visibly diving under brakes and getting light in the rear end is going to be either too little front shock, front spring, or anti-dive geometry. Or a combination of the three. Shock and spring is where I'd be starting.

It has fair bit of bump valving in the front shocks and we can't run high spring rates at Oran Park as it is far too bumpy since there hasn't been any track maintenance for 3 years. It could do with a little more anti dive geometry, but it has lots of front braking capacity (in excess of the rear) so I was reluctant to suggest to Stu that he reduce the front weigh transfer too much. Lest it start locking up front brakes, which is not good for an inexperienced circuit driver.

Its two weeks away. Don't you just need a clutch to make it drivable.

This isn't Fast and Furious... Parts don't automagically come "overnight from Japan" :)

I'm assuming that it'll be at least 2 weeks before I see the clutch...

Ben - Do what I do, and work from the track...

Sure, you might have to put up with Duncy Dinosaur pointing and laughing at you whilst you're hiding in your car making a few phone calls, and you might miss a few sessions here and there, but beats being in the office! ;)

Stuart,,,I'll echo what some of the boys have said,,,I would add a real rear spoiler,,,dual plane adjustable nothing less,,,no gay drift rubbish but a real one. Gary will know where to find one and him corner weighting the car will help heaps,,,you might find you have to transfer or add weight the rear.

What about lowering the fuel tank,,,A9X style.

Turn 2 could be just be you carrying to much speed,,,you won't be the first or the last to mow the grass there. Ando and I were laughing our heads off,,,we both could see what was about to happen,,,Sorry tiger but it was funny. Interestly Ando had time to watch,,,pull another cog,,,laugh and toot the horn.

I'll keep you to that drive mate by the way.

What ^^^^he^^^^ said :( My wing is certainly no engineering masterpiece, cost me a sweet $100 smackers 2nd hand.... As mentioned it could do with sitting higher and having a dual plane, but on a Team PSR (Povo Spec Racing) budget, my $100 wing will do just fine ;)

Hey hey i had time to do all that simply because i slowed down and pulled out the popcorn to watch the Yellow Tug Boat 'slide' into dock..... :)

you think that's bumpy, you should see QR & lakeside! Apart from turn 4, they make OP GP look like a billiard table.

as for the wing suggestions, that's just a band aid solution. At best. You're far better off working on mechanical grip first. Oran Park is a low speed circuit anyway.

So Harry are you saying a rear wing is not a good idea?. I agree O/P is not the fastest track but you still need down-force and rear end stability through turn 1, and a couple of other short straights that have your foot mashed.

I'm saying its not a good idea to try and fix his stability problems by adding a wing. He's got issues with its mechanical setup. Don't try and fix that with aero. Treat the problem (excessive dive) not the symptom (rear end instability).

hey big boy. I was gutted I couldn't get out there on friday to see the beast. :) but so pleased it went well.

R32s trying to swap ends under brakes is a very common trait.

a few things that will help.

what are the current camber and toe settings front and rear?

if you don't already some toe in on the rear will help stop the back from trying to overtake you round the outside!

also driving style helps too. the R32s do not want you doing any turning under brakes. trailing any brake as you turn in will see it want to swap ends. this is especially prevalent at turn 1/2 oran park as the track slopes down a little that way too.

after you've done any alignment and driver adjustments then look at springs/shocks/bars/geometry changes.

anyway, spinning off a few times at least shows you are trying and no doubt when you get the hand of it you'll be quick. :) well done.

It has rear toe in, plenty in fact.

My guess is it has so much bump steer at the front it is unstable under brakes and sawing away at the steering wheel correcting the bump steer is unsettling the rear end.

unless the front end been significantly altered it shouldn't be any worse for bump steer than any other R32 - except for the amount of pitch its getting under brakes, which certainly sounds excessive from the descriptions. less pitch = less bump travel = less bump steer.

The steering rack location has been significantly altered.

yeh its something that was overlooked when mounting the rack, but can be rectified, not sure why it would be causing me issues only in turns 1 & 2. I had less trouble later in the day after some instruction on my line into turn 1. but turn 2 was still an issue, i think i wasnt braking hard enough and going in a bit hot while still trailing the brake. Ill have to give it another go and try some changes on the day. i just wanted to drive it on Friday.

ah... have fun with that one!

It's curable, just needs a bit of time spent on it. Time consuming yes, but not hard, just work through the processes.

It may need a little less brake bias to the rear, but that's also easy to fix. But first we fix the bump steer.

  • 2 weeks later...

sorry as there has been no updates as i havent touched the car sinse OP, have been preparing spare bedroom for my daughter as to prepare her current room for my new arrival who decided to join us at 11.55am on sunday morning. Gorgeous little girl weighing 3kgs and 50cm tall. Mum and new daughter doing well, still havent named her.

ill give it a couple of weeks for them to settle in at home and then ill be back into it.

Thanks for all your suggestions and input also, just have been offline for a while and unable to reply till now.

    • 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 it's 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 damn hot in there, that made it all the more easy to remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. I was standing there looking at the car and said 'f**k it'. 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.
