Sorry to hi jack, but I like the buggy! Is it a custom build or designed for a race series? Where do you use it?
Custom build, but we do race it, was originally made off beetle parts just for something to play in though!
I might stick a thread up, just didn't seem like quite the right place for a build thread

Thanks - I was getting a bit worried with my understanding. I have had this argument before with someone who suggested that a hollow tube is stronger
than the equivalent solid tube.
I suppose, like anything in engineering, there is a compromise to be made between wall thickness, torsional strength and buckling.
For a given weight, a hollow tube will be stiffer since it's diameter will be greater. for a given diameter the solid one will be (a bit)
stiffer.

Westfield's effective ARB is a length of CDS with ends welded on to it, works wonderfully.
My widetrack Westfield solution was to extend this bar with a section welded into the middle. It worked beautifully on the track, raced ruthlessly.
Whatever the nannies say, just get a length of tube and go play.

If it's interesting, has wheels and an engine, this is the right place.

It meets that, I'll stick a thread in Maintenance and Mods later on.

Done!
Seamless tube is pricey isn't it? The new bar is made, painted and this evening it was fitted. The standard 'stand on the sides of the
chassis and wobble from side to side' test shows that it is a lot stiffer than the Fiat bar, though bouncing on one side of the chassis shows
that it does allow one side of the car to move independently of the other. The lesser known 'put your foot on the rear wheel and hang off the
roll over hoop test shows that the car now hardly leans at all. This, I hope, will put an end to all that pesky body roll.

Seamless is cheap, you want to try having a car built out of T45
