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;
