    Hi folks,

    The rear of my 69 kombi needs to be lowered to match the front - sits up just a bit high.

    Hence, I need to lower it in some way and was planning adjustable spring plates.

    The rear adjustable torsion arms provide good adjustment to make sure I get the right height and level.


    Anyone used the Classic VW torsion arms? Or the DAS Resto Haus version?

    Or any other tips?

    Thanks

    Hi Scott,
    Call me wrong but I just thought it was a case of move it around on the torsion bar splines.:confused:
    Cheers

    There's only limited room for movement on the splines before the plates hit the bottom stop when raising - it's a lot easier to get right with adjustables

    Have you checked out the Indian Automotive ones ....... just checked but nothing on the web site now ....... may still worth calling Mikki ;)

    VVDS may be worth contacting if you haven't yet :rolleyes:

    Rod Penrose ?????

    On late bay, measured at bottom of sills just outside each jack point I got 22mm rear drop with one outer spline.
    Worked OK with drop spindles dropping front at wheels about 50?mm​

    Thanks Col.

    My front is OK as it has drop spindles - but no adjustment there.

    Dropped it a tad too much and now the back needs to come down a bit.

    So much easier to get exactly the height I want with adjustable rear spring plates - not too low or it wont get up the driveway without dragging the rear bumper.

    The 69 bus has already drooped at the rear from the weight of the fuel tank, gearbox and engine but not quite enough.

    Yeah. Understand that the fine tuning probably worth it/ necessary.

    I thought a few smaller ones would be more adjustable - just keep adding until desired height is acheived. :D

    Na.
    Fully adjustable.
    Just shift position.
    Keep away from humidity tho.
    Once it sets it tends to slide around ;)

    On a beetle you adjust inner and outer splines to get height changes of 0.5 cm.
    If you just do the outer you get 6 cm changes

    I assume busses are the same.

    I would NOT be using no name adjustable spring plates on my pride and joy.

    PS - engineering is not possible unless Porsche trailing arms used

    PSS - gotta love T3's

    On a splitty with an IRS conversion 68 adjustable spring plates are used.
    I had a set of Indians and they snapped at the adjuster tab block. Pretty sure this is why Indian dont do them now.
    This is not uncommon with them and other makers I suggest, made in a similar way aka CVD.

    I replaced mine with Creative engineering MUCH STRONGER , Roy has them for about 650 plus or they are 300 plus Direct from creative.

    Thanks all for the advice - might go with the Rod Penrose stuff as he has a good reputation for quality bits.

    Either that or the inner and outer spline adjustments which sounds time consuming and therefore very expensive.

    Inner and outer spline easily within your skills Scott.
    Therefore cost zilch.

    Give Rods a go tell him your only concern is it snapping there and he will back it im sure. 195 a lot less than 665! Rods look stronger than the Indians that broke. I think its about the amount of metal on the short piece where the block is welded.

    Problem is Col, its a really old bus that could do the sag on one side trick to me after playing with everything and marking positions etc.

    Could be easily rectified with the adjustables.

    Thanks Barry.

    Now that is very helpful.

    If Rods dont work I might just have a go at the splines o_O
