Ämne: Rear antirollbar

[rwd-student]

Has anybody done it here? My 340 has the coilover koni shocks, but it still rolls a lot. Is the double leafspring a better solution than an ARB?

What are the experiences about a rear ARB and/ or double rear leafsprings?

sorry for my strange poll

Hi! Sorry but I think there is no one on this forum that has tested with rear ARB.
But double leafsprings is several cars modified with.

ARB= Anti Roll Bar for them who isn´t familiar with the expression.

I've seen once a rear antirollbar at volvo300mania, and one for real at a group A rallycar. Unfortunately could'nt take a nice/close look.

The 363 also has one:



But how does the double leafspring handle?

[Mefistofeles]

You have one reaction arm on the right leafspring, mount one on the left side too. It should make a big improvement.

[rwd-student]

Thats a good one. I can imagen the rear itself is more stable that way. But it doesn't cure the bodyroll right?

Thanks

Stiffer I believe.. but haven´t tried my self yet.
I am also going for Whiteline front ARB and custom rear ARB when we get one that fits with some mods. The 363CS solution looks nice and easy! Wonder what that ARB:s manufacturer is?

No for less bodyroll the solution is stiffer springs&dampers or/and ARB I believe.

THANKS for that thread! We (I) here on 300 Power doesent follow all the action at V3M so hard..

There are a LOT of interesting threads on 300mania.. Worth a look, but it goes fast (into next pages).
Seen the front coilovers from adam?

I'll probably try the double bladfjädrar, maybe the swaybar and reactionarm too. But it will be over time.

Yeah, I've got one vote for not speaking Swedisch

Yes I saw the coilovers after I read the thread about rear ARB. Had been nice with more pics of the Beemer ARB mounted to the body. 

The best thing for road-use should be ARB instead of double leafsprings because of the comfort. If that not enough then try double leaf springs. But you mabye drive so much on the track that you want superstiff rear soon!?

[rwd-student]

Comfort doesn´t matter to me indeed. The double leaf is the quickest and easiest way I think.

 I´m gonna lower it first, I´ll see how it handle. The front needs low too, but there isn´t much travel left. Stiffer springs on the front are probably a must, to not bottom-out all the time. And I want the most weighttransfer on the back, so the back has to be even more stiff than the front.

I´ll see how things go. Keep it updated

[FREJ]

Stiffer springs on the front are probably a must, to not bottom-out all the time.

But if to hard it will "top-out"?

And I want the most weighttransfer on the back, so the back has to be even more stiff than the front.

Explain that to us non track guys please 

[rwd-student]

I just mean if the front springs are to weak, it will hitting the bumpstops. When that happends there is no really "control" over the wheel, because the forces on the tire are to high and lose grip. So you might suddenly getting  understeer. By big bumps its allright to hit the bumpstops offcourse.
If the front springs are to hard (compared to the rear) it gets more understeered.

If the rear is stiff and the front weak, the inner rear wheel will be lifted. Witch make it easy to oversteer. You only have to brake grip of one tire Watch this:



Otherwise, if the front is stiff, and the rear week, the inner frontwheel will be lifted. Wich makes it possibel to put down all the power at the rear axle.  But is probable more understeerd in first reaction.




But its hard to explain, definately in a other language. There are so many things that can change the situation and the reaction of a car.. Its a study you know :]

[FREJ]

aha now I get the thing with weight-transfering!

Thanks for the good answer!
