What's this

[Leebo]

Hey guys i just want to ask what this is in the photo i have taken under my bonnet.

Is that factory or something?

Yip factory as they come, its a front sway bar

[Leebo]

So if it has sway bars does it have one on the rear (probably not)
what are the aftermarket ones, just adjustable or something? i saw a red on a VR wagon looked the same diameter.

You have front and rear swaybars. They help control body roll.

Thicker swaybars keep the car more level in a corner, softer ones allow for body roll.

If your front swaybar is too thick, you can induce inner wheel lift in a corner, as well as understeer. If your rear swaybar is too thick, you can suffer from premature oversteer.

Aftermarket swaybars can be thicker, thinner, adjustable - just about anything you want. They're a good way to make your car handle firmly through corners without having to run hard springs, which most people to do compensate.

I used to have a 32mm one on the front and it was hard as but not very good imo

The yellow ones go faster

Okay i get it now i read somewhere that you put sway bars as a last option of you cant get the suspension how you want. eg/ shockers and springs etc

[Morton]

lol. They're not a "last option". On their own, they won't help bad shocks and springs. But that said, a bad swaybar setup will show through good springs and shocks too.

[Calaber]

To get the best balance, it's important that the sway bars, springs and shocks complement each other (and that doesn't mean talking to each other every morning saying how nice they look).

If your front sway bars are too heavy for the spring settings, as already mentioned, you will end up with a car that handles like a dog, understeering like buggery. ( I know, I did it on my HR). You will find that there is usually more than one diameter sway bar from the factory for each model (ie 6's have one setting, 8's another, utes another etc.) because of the differing body weights and spring/shock settings. Just as an example, the early 6 and 8 cylinder Commodores had front and rear bars, the 4 cylinders didn't have the rear.

They're certainly not a last option - rather, they are a very vital component.

[immortality]

sway bars can be used to "tune" the suspension .i.e. for under/oversteer as morton mentioned. get it right and the car will handle like it's on rails, get it wrong and you could findyourself wrapped around a tree.

generally, from factory, cars are setup with understeer. it's safer. in a understeer condition basically whats happening is that you turn the wheel but the car plows on straight ahead, basically the front tyres don't have enough traction. the best solution in this situation is to reduce speed and allow the tyres to gain traction. seeing as the majority of the driving public hit the brakes when something goes wrong it's the safest way to setup a cars suspension.

the same reason why front wheel drive cars are also safer. loose traction because your giving it to much gas and the car will just go straight ahead, take foot of gas and apply brakes and you regain control and are probably still going in the same direction as intended.

with a rearwheel drive car thats setup for oversteer, loose traction through a corner and you find you'll be looking at the cop thats following you as you slide of the road heading for that tree you were looking at 2 seconds ago

[Leebo]

Yeah that that's a better way to describe it it's a way of tuning the suspension.
And there's no point buying red ones from pedder so you can stand around bragging about your sway bars.

I didn't realise the car already had them but I'm sure the factory ones are fine for street use i don't race.

[Morton]

Yeah, factory ones are great You can even tune a car to corner reasonably well with factory swaybars.

[ScoHar]

if your going to get anything for the sway bar, I would suggest the lower arm conversion mounts, It takes the upper mounting of your link pin (attached to side of shock) and moves it so you can mount it to the lower arm, imo this made a difference.

[Leebo]

I think i will be fine with these i just brought new shocks

[Morton]

Yeah, you'll be just fine mate New shocks will put your car in better stand than most VNs out there ^_^

[Leebo]

Yeah well with the new shocks being shorter stroke sports rider ones i have it lower and comfortable and the car handles better tan factory.

Got the adjustable panhard rod to suite just want a strut brace and will be sweet
