What are the best c.v.s to use in a off-road kombi? The wheel travel will be increased by a few inches and the motor will be making a lot more torque. Can traditional VW/porsche C.V.s handle heaps of travel and punishment? I know range rover designed a new style of C.V. joint on the latest models to cope with the new long travel independent suspension, but I shudder to think what they would cost. What do racing buggies use?

The kombi CV's are very strong and hard to bust but are limited by the fact that they cant handle the angles of a jacked up rear end. (max. 22 degrees)
Offroaders use Porsche 930 CV's due to their strength and ability to be run at a greater angle.
I would say that you cant go past the porsche or the VW CV's for strength and unless your running big shaft angles kombi ones should be fine. Cheap and strong.

pm Craig Torrens - he has done a bit of research into this

If you find somewhere that sells Type 4 CVs let me know.

I see the 930 C.V.s are good for 25 degrees, the new range rovers are good for 51 degrees. I think I'll get some prices and see how I'll go. Thanks.

51 degrees on CVs what can I say but holy hell. Let us know how you go with them they sound like just the thing.

51 degrees sounds like steering CV's, might have a bit of trouble mounting them up.

What is the cost of the Porsche 930 CV's?
And what is involved in mounting them to a kombi?
Are they a straight fit or is some work required?
Thanks.
