    Hi all,

    I am a new member and this is my first time asking a question.  I just purchased an MiGi TD replica on a 1966 VW chassis.  The front suspension is sagging and I was wondering if the torsion bundle in the tubes could be removed, turned over so the twist is in the opposite direction and re-installed.  Would this lift the front end back up or do the bundles need to be replaced?  The second question is in regards to the rear suspension.  I think I have a FiberFab MiGi TD and it looks like there is not enough clearance to pull the spring arms to index the spline to raise the rear end of the car without removing the body.  Is there a way to do this or is the easiest solution spring over shocks?  Thanks for any input.

    Greetings Larry, and welcome aboard!

    Turning the torsion spring leaves upside-down would have little or no impact because their neutral position is flat.

    The FiberFab build manual, located in the library, describes how to modify the front beam, decreasing the spring rate to accommodate the much lighter front end of the MiGi. basically, FiberFab advises cutting the center section containing the torsion bar mount loose from the upper tube, then welding it back in at zero tension with the beam a specific height from the ground. This modification has been done on mine and the front ride height seems correct. Others on this site have expressed displeasure at the recommended modification, and instead advocate removing the narrower torsion spring leaves from both the upper and lower tubes, leaving only the wider leaves in place.

    Were I in your shoes, I’d examine what was done to your beam and check for broken leaves, then develop a plan of action. There are plenty of videos on YouTube showing how the VW front beam is assembled. Prepare to get greasy, it’s a really messy job.

    With regard to the rear, perhaps yours is built different than mine. I appear to have enough room to re-index the splines by removing just the rear fenders, not the whole body. Although I don’t need to do so, the rear ride height on mine also seems correct.

    I have decided that the front suspension will be fine as it is.  On the rear I had to remove all of the body bolts from the pan and lift the body about three inches to allow the removal of the plate that holds the torsion arm.  Once this was done I was able to pull the torsion arms and re-index the splines on the torsion bars to get the proper ride height.
