After spotting this ARB system while searching for info on monocoques, I came across this setup on the Porsche GT...
despite the wide array of cars I've worked on I've never come across anything similar, but it would solve 101 problems I have if I could use
similar - anyone know of a car with the same system of levers, or an ARB specialist that may be able to assist?
If you could get a look at a Metro 6R4 they have an adjustable version at the front which uses a rotatable blade to adjust the stiffness.

cheers, will have a look at both.
Its just a perfectly normal anti-roll bar (i.e. torsion bar) loaded though pushrods from the bellcranks.
Think laterally, as long as you load the bar in roll, and it resists that movement, then its an anti-roll bar.
Gets interesting if you use a monoshock and mount it on a centra flange on a sliding bush arrangement and spring it either side of the flange.

The idea is for the horizontal bar/tube to provide the torsion spring element, but I can see why you would ask the question as the arms do look a little flexible.....perhaps they are intended to flex somewhat...in fact they'd be bound to really.......

This is the one i'd like to know how it works.

Oooh, that's quite techy that set up is! Is there any real point in such a set up for a road car at all?
It also looks as though it has dampers in the setup up because, of course, an anti-roll bar is an generally an undamped spring.

This is real neat because you can change the "ARB" stiffness so easily. The springs it uses are known as die springs and they are available in so many different rates for cheap because they are industrial instead of race car.
What happens is in bump or droop both links move together and the bar rotates. When you have roll one link must effectivley shorten and th other lengthen so the "bar" moves to the side compressing the springs. You could choose to have different roll rates in left and right corners if you wish.
..........and read what I said about monoshocks, same setup, different layout.

Of course there is! When you go to a car meet and pop the bonnet open everyone gasps and mentions what a techie ARB system you have. Well it's certainly enough to make me think about it
irony is key to my sense of humour as well 
you will really need to know what you are doing to use that design......
I'm not even fitting anti roll bars to mine for the initial design but then as the car is so wide the roll angles will be smaller anyhow.

Forgot to mention the Mosler has a similar roll bar on both the front and the rear.
I have some pics of it on the other PC but can't post any up until I finish with the internet connection and can plug it in.... actually I might
email them as I don't have the hosted.
email would be great, cheers Andy.
