Swaybars?
|
Tue, 24 September 2002 22:31

 |
On a RWD car which would be the best sway bar to get first?
The front one looks to be quite large (23mm) but the back one looks tiny. How much differance will a front / rear swaybar make?
Cheers
Wilbo

i think front reduces understeer and back reduces oversteer, but i'm probably wrong on this one never looked into the matter my theory is just put sway bars front and back

Rear wheel drive needs to have a lot smaller bar on the rear than the front unless you like sudden unpredictable transfer to oversteer. This allows the front wheels to stay on the ground for cornering, & helps the back wheels to get traction by transferring weight onto them.
Front wheel drives need bigger bars on the rear to stop weight transfer onto them as you need weight to stay on the driving wheels.
Either way, get the front bar first. It might look big, but the stiffness depends on the steel used & whether the bar is hollow or solid.

Other way around dude. 
Front induces understeer, and vice versa.
As Steve said, get the front done first. You don't want to drive a RWD with a soft front and hard rear....

So where do you get swaybars from?
I am interested in trying them out on my '98 Celica SX.
Any recommendations would be appreciated!

Get both while you're at it. They're not that pricey, and they do a good job, something every car should have

Front $199

Not bad really!
Will they really transform the car tho?

ive heard that fitting a front and a rear swaybar can screw your handling up, does anyone else know anything about that?

Fitting front & rear sway bars was the single best improvement I did to my '96 Vienta (previous car). Absolutely changed the car's handling (which was far from perfect in stock form).
Installed a 26mm front bar and a 22mm rear bar for a ridiculous improvement in handling and turning response. Cost $550... every cent worth it in my opinion.
I want to replace the ones on my Soarer one day (silly hollow tubes) with solid bars, but am a little more wary, as I have twice the power and only 200kg more than the previous car. Not a fan of uncontrollable sideways action, but I do know that I definitely need to change the front one first.

I bought mine direct from K-Mac.
Swaybars will give you an incredible improvement in controlling body roll.

So the K-Mac bars are the best? More solid?
What about ajustable panhard rods? These are hollow right? Would this be a weak point in the drivline? I mean would a hollow bar be suitable for a panhard rod?

If you lower the car you need an adjustable panhard rod don't you? Do you have to buy one or can you just cut the old one and weld in threaded pieces to make it adjustable?(too weak?).

Well thats what i'm wondering! But if all the ajustable rods are hollow i'm thinking that there must not be much load on the rod?
Thinking about it, it does'nt really do to much

The basic idea is, if you lower your car, but don't fit one, you'll have your diff hanging off to one side...

Yeah I get what the effect of lowering is on the diff via the panhard rod, what I am interested in is the possibility of making an adjustable panhard rod out of the original!
Or should you just buy one?
How much are they? Probably not that much, just curious is all!

They are $109 from whiteline!
What I want to know is what kind of stress is on one of these?
Is a hollow item ok for just a street car and do I need a solid for a race car? What do I need?

Sort of.. I'm just worried about the rod flexing and then snapping  This could be painful

Pan hard bar stops diff from moving side to side, doesn't take a huge amount of strength to hold it as you also have all the trailing arms and so forth.
it would only be a big issue on a very heavy car.
the only time i've ever heard of a pan hard bar braking and thats from some sort of impact such as a gutter and so forth.
your main issue with cutting it and putting in a threaded link would be corrosion of the two different metal types and thats what would caue it to most likely break

and a for hollow ones, well depends on how hollow it is, often some sway bars are hollow and think of the kind of stress they have to handle where they are always trying to flex but have you heard of one snapping?

Just remember that the panhard rod does stop the diff from spitting out the side of the car! Now imagine the load on it when screaming around a corner This is exactly what i'm worried about

i drove home without a pan hard bar and sure it moved around a fair bit but you would be surprised at how well the trailing arms keep it held in straight, as well as shocks and so forth all hold it in.
if you want to see how much work it actually does disconnect it and go for a drive around the block and you will see its not a big strength part of the car just a stabliser.
as for Troyboy, adjustable would only be good for track and if you actually know how to adjust it,
but could you ever be bothered climbing under the car and always frigging around with the adjustments to work out the best ride?

Troy, you should talk to Dave (dnation). He knows quite a bit about suspension mods on AE92s.
manipulate. You don't really need to upgrade the swaybars... Swaybars also provide similar improvements that stiffer springs proviede... The are pros and cons about each and getting the right ratio between swaybar and spring is a black art...

take V8 supercars for example, they have to keep adjusting there sway bars through the whole race depending on fuel load and tyre condition,
but suspension is to hard to fully understand anything and you should really find a place that really knows what there talking about and ask them what they think should be done to the car, let them have a drive off it so they see how it feels.

A panhard rod is designed to keep the diff centred in the car for a given range of suspension movement.
This means it MUST stop the diff from 'spitting' out the side of the car.
