Who has what and what's the result? From Ratwell, I think front and rear would be good as I want stability in cross winds, but he also says front only is a good compromise if a bit understeery. Stock height, new stock (Boge) shocks.
I was reading about these recently. VWH seems to recommend/offer a range of anti-roll bars and gas shocks. Do they affect the ride, handling that much? Cyril goes fine, but does 'float' especial around corners if you know what I mean...
Floatyness is a feature of the torsion bar suspension - it's meant to be like that! Also known as "nodding dog" suspension...
Floaty is OK by me, it's just the unintentional attempted lane changes in cross winds that I don't want.
Theres a good suspension guide on Creative Engineering's site that reccommends removing the anti roll bar if you've got a lowered bus.
That is, honestly, play somewhere in your steering. I fixed mine up and, although I get tugged by strong winds, I don't do the "three-lane-change" bit any more.
It does also depend where you are driving. I can drive mine nd it's predessessor pretty well anywhere in the uk without much problem, but as soon as I get back to the fens it's hang on time.
The steering compensates OK, but the van rolls a lot and then rolls the other way when correcting back again. It's not comfortable for passengers and requires a lot of concentration when driving.
I'd try the heavy duty anti-roll bars then. @pete Davies fitted them to his full height bus to stop this and was pleased with them I think but the last time I saw him was following him on the way home from Techenders many years ago while he deliberately swerved from side to side to test it and show it off. Not spoken to him since as he disappeared to the world of downhill mountain boarding.
The more you write, the more I think your camber is set wrong. Swerving one way then the other in uncontrollable over-compensating sounds like mine was when the camber was out. Stand in front 20-50ft away with wheels set straight and look at it - the tops of the front wheels should be quite obviously further out than the bottoms.
Camber is set right!! I set it after it was feeling unstable in bends... one side was ok-ish, the other side was over 1° out!!
I wonder if there is also just needing to build experience with a vehicle which steers more like a speedboat going over waves than a car... It will not go exactly in a straight line but if you try to overcompensate the steering you will start to snake. Some of the wobbles will cancel each other out in the end. On a calm day and a flat road you should be able to let go of the steering wheel and the bus should run straight. I gave up learning to drive in a Mini at age 17 when I got to 60 mph and then swerved all over the road as I overcompensated on the steering for small wobbles. And I have managed to spin out a go-kart on a straight section on an indoor track, so I know the tendency is there in me.
Steering components are all tight too, and I think the rear donuts are good too... As I had the back end to bits to level up the saggy rear!! I put a new drag link in, as that was the only steering component that had a small amount of play... everything else was tight as a drum
