Well lets think:

Tyres, springs, dampers, bushes, suspension geometry, unsprung weight, differential type/setting all have an effect.

Further ride height, rake angle, toe settings, camber settings, caster settings, tyre pressures have an effect.

So maybe you need to start by having a think about what you want to achieve.

Do you want, for instance a nice compliant ride to take your Nanna to church on Sunday or something more tuned to lapping your local circuit? Or something in between?

What you would change depends on what you want & also on what type of car you have.... :laugh:

Start with sway bars front and rear - see SydneyKids group buys

Even with stock suspension, this will make a big difference to handling and is also the cheapest option to start with.

yeap...

a general thing is that people start by throwing in coilovers in straight away.

the standard spring rates on skylines are actually pretty good.

front and rear swaybars are the best bang for buck mod i've done suspension wise

I'd say an advance driving course or specific cornering course would be the first to do.

No point in having upgraded suspension if you don't know how to go through the corners.

I'd wager that most people on here would benefit more from learning to drive fast correctly than just upgrading suspension.

I'm sure people on here could tell you more about them.

It would depend where you are and what tracks you are close to.

I did one at malalla a few years ago when i had the R34. And it was great. Went all day and included lunch.

They taught me what kind of lines to take, how to balance the car when coming into a corner, and just made me a faster smoother driver.

And you will be grinning all day on your first time out, it's just awesome. Espicially when at the beginning of the day and your going into some corners at 70 kmph and your thinking to yourself "i'm doing pretty good" then by the end of the day your doing the same corner at 105 and having an absolute blast.

no point taking a slush box to an advance driver training course..... fix the sloppy handling, then learn how to put it to its greatest effect.

I completely disagree with that. It would take more skill to drive a crappy car fast than it would to drive a good car fast in the case of a skyline.

It's all well and good to have the fancy bits, but no good having them and not using them correctly.

Can some ppl start trying the Cusco/Jap swaybars. They are a bit lighter and im curious to know how good they are...as im all ears for dropping an easy couple of kgs out of my car :P

justinfox has the cusco bars. and I will be using them soon too. ;)

Hmm, maybe I can add my 10 cents worth.

Firstly, funny how no one seems to care what outcomes the bloke may want to achieve from his suspension upgrade.

Secondly, upgraded sway bars are great except:

1. If you want to go drag racing.

2. When the shocks on the car are stuffed.

In which case they are basically a waste of money. I put new sway bars on my tired stock suspension (They turned up first, ok) & basically they didn't make sod all difference to the handling other than exacerbating wheelspin by hiking the inside rear.

As for the bloke who reckons driving a car with stuffed suspension is a better learning experience than driving a car with sorted suspension. Well I hate to burst your bubble but driving a car with stuffed suspension only teaches you how to drive a car with stuffed suspension. You end up making feeble, timid inputs (brakes, steering etc) because of too much weight transferance. Now that is fine up to a point, but getting the best out of a sorted car is a very different proposition.

Now Cusco sway bars may be good (in that they are, atleast hollow) but they aren't worth a pinch of shit if they don't match the spring rates fitted to the car. The rates for the Cusco gear is very different to the rates for the Whiteline stuff. So as a direct replacement for those running Whiteline spring/shock packages they aren't much chop. :( Why? Because the front Cusco is softer than the Front Whiteline & the rear harder than the rear Whiteline. So you would need to have fully utilised the adjustment on the Whiteline gear before going anywhere near the Cusco stuff.

In anycase I really don't believe that running less front roll stiffness than the Whiteline setup would in any way help a GT-R to corner better. Running yet more rear roll stiffness will simply remove even more load from the inside rear when turning. So the damn thing ends up looking like a WRX. Funny how no one mentions such things as roll centres, cog, ride height etc etc etc...

Must go, tired now. :dry:

How to improve the handling and stability of the car?

what parts must be change to achieve that desire results?

Step 1, fix whatever is broken or worn out and then get the wheel alignment correct. This usually means some adjustable bushes for caster, camber and rear subframe alignment.

Step 2, stabiliser bars are the best bang for buck suspension upgrade you can make for improved handling. Road or track.

Step 3, shock absorber upgrade, if the standard shocks were OK in step 1 then it is now time to upgrade.

Step 4, aftermarket springs if you want a lower height than can be achieved with standard springs and aftermarket shocks (ie; The Bilsteins in the Group Buy come with additional circlip grooves which enable you to lower it using the standard springs. Around 24 mm works very well).

Check out the Group Buy for your particular model;

      Pops when backing off throttle, rough-ish sound through rev range.

      By GTSBoy · Posted

      Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
