Found this pic of the megabusa suspension on JC's site.

Was wondering what the extra bar and tie rod are for?
I guess that this is some form of anti roll bar. Can't make out how it works though.[img]http://locostbuilders.co.uk/upload/a47636-DCP_0006[1].jpg[/img]

Yep, looks an ARB to me...
adjustable one too...

You can only see the lever arm, the torsion part of the bar just runs from side to side...

Yup, definetley an ARB that!

does anyone know what the adjustment is like on this type? is a case of changing a bar of certain stiffness that runs through the middle of the bodywork or is it on a pair of knife edges that deflect/adjust accordingly?

Ned.

alter the clamp at the top of the drop link up or down to alter the amount of 'flex' in the system. the rotatable knife blades offer greater adjustability but can be more difficult ti setup IIRC

Kind of related.....

anyone know how the Dax Rush fancy suspension works? - any pics?

BTW TimF - whreabouts r u ? - just want to know wether to get triple glazing installed for when you have that beast running!

I'm over nacton way so should only be a little disturbed by the noise!

With all that hair, I'm suprised you can hear anything!

Got any birds nesting?

I found an article about the dax suspension ages ago which explains pretty well how it works. It's a bit clever really - basically the wishbone geometry is set up to give about half the desired camber change in roll. During two wheel bump/droop this camber change is cancelled out by the linkage keeping the wheels vertical, and during roll the camber change is increased by the linkage to the correct level. I imagine it would be an absolute pig to try and copy it and actually get it set up right, and if you got the geometry wrong you could probably end up with worse suspension behaviour than conventional wishbones (not to mention getting told off by Peter Walker).

I've popped the scans on my webspace so you can have a look. They're about 400k each though...
