Front Torsion Bar Repair

[David Jones]

There is an aftermarket adjuster available for the VW beam, but the beam has to come out of the car to weld it in. that is the expensive part of the mod.

I think this diagram shows the grub screw and the adjusting screw.

[Mike DeJonge]

not really the adjustment, the grub screw, on the VW torsion tube is on the front of the tube, which does not match the grub screw on the rear of the 356 tube. So if you replace the leafs inside of the 356 tube with VW leafs the indentation or the dimple on the VW leafs does not match for the 356 grub screw. You will need to modify the VW leafs to work in the 356 tube, either by welding or drilling a new indentation, and this could weaken the leafs and cause them to be weaker or break

[Vic Skirmants]

If you simply grind a new indentation in the correct location, I don't worry about weakening the torsion bar. It is clamped within the block, so the twisting loads pretty much end at the edge of the block.
