Tubular subframes?

Has anyone ever seen or done anything like this?

Any idea what type of material/gauge would be used for something like this?

 

No but there was an American dude who posted something like this a wee while back I seam to remember.

 

I made a thread on it here.

 

Found these bits:

Is it Eric Langbein your thinking of?

My photo bucket is down so you will have to wait until the 26th before they return.

 

Very cool thread, I like it, have you moved the ideas on at all?

Surely the rear beam would be very easy to replace with a tubular item?

Have you established what type of tubular material is the best candidate?

 

Rear beam is a very complex structure, would take a lot of engineering knowledge to remake effectively. Even top line euro hillclimbers still use them, albeit modified.

That is the one I was thinking of but not able to track down, some clever stuff.

 

I've contacted Eric for more info, would anyone else be interested in tubular subframes for their mk2?

 

It depends on how it improves the car. Are the suspension pickups moved to give better geometry?

 

Im still waiting on a response but i'll ask.
