Topic: Lowering a '79 bay

I want to lower my 1979 bay camper but have heard so many ways of doing this that I'm abit confused as to what to do!!! I've been told that some ways are cheap but dangerous, but some are really expensive!!! Just wondered what other peeps had had done??? Cheers, Dan.

Re: Lowering a '79 bay

Not done a bay, but lowered the beetle using dropped spindles which gave it a nice low but useable stance.   

How you lowere it may depend on budget and or skills with the welder

Well doctor it went ground ..sky... ground... sky....BLACK

Re: Lowering a '79 bay

well it depends how low you want to go?

rear is fairly easy (about half an hour's work if none of the bolts are a pain to get undone) you just take of the swing arms, move them round a couple of splines and put them back on.  If you want to go very low then adjustable spring plates is the way forward.

the front...  the "best" way to do this is to buy dropped-spindles...   these are replacements for the steering knuckles currently in your van that have the stub axles sticking out of them that the wheels fit onto.   Drop spindles are made simply with the spindle further up the knuckle thus dropping the height of the van.   This is considered the "best" becuase it doens't change any of the geometry of the rest of your front suspension which means it all still works normally under normal stresses.  the downside here is that dropped spindles come in fixed amounts of drop and you're stuck with the drop you bought so make sure that very expensive purchare is right for you.

the second option is to fit adjusters to the beam, the front beam is two tubes containing leaf springs which work tortionally.  the leaves run through clamps inside the tubes which hold them in place.  the adjusters are fitted to both top and bottom tubes by drilling out the retainers that stop the clamp turning inside the tube, fitting a grubscrew and a pair of toothed plates allowing you graduated adjustment

see here http://www.splitterz.co.uk/forum/viewtopic.php?id=207

now... this reduces the tension on the leaves under load and thus drops the suspension... however.... this also means the rest of the suspension is running low in geometry and you are relying on the two grubscrews to hold the front of your van up...  my bay has been running on those since 2005 no problems default/smile

the third option is usually called "cut and turn"  which essentially is the same as fitting adjusters but the whole thing is welded back up once the right drop has been made.  more permanent and durable (possibly) than adjusters although it really does depend on the quality of the welds.

the only thing I would really recommend you avoid is the single adjuster fitted to only one tube instead of the two adjuster setup i mentioned above.  the single adjsuter simply takes the slack off one set of leaves and actually forces more tension into the other set as a result...   this gives a low but very springy ride and the two sets of leaves are under differing loads and that jsut can't be a good thing over the medium to long term.

of course if you want to go really low then drop spindles and adjusters..   then cut the tops of the wheelarches out and "tub" them up into the cab to make room for the wheels and...   ahhh well that's a whole different kettle of fish.

in terms of who I'd recommend to do the work,  Precious Metal in Billericay, one of our forum sponsors and I've jsut been on the phone with Nige and I know he's got a pair of T2D drop spindles and some adjsutable spring plates in stock at the moment so if you wanted a 3.5 inch drop all round the stuff is already there to do it:)
