You never know but the interweb is a strange place .......... and the boot in an A4 is rubbish!
Anyway everything is relative

My 2002 Allroad had a decent boot and at least the rear seats folded properly flat (not long enough to kip in though)
Good handling car though, but hefty at 2000kg. Only 25k from tyres at best on special Pirellis, £150 a corner...
Variable height air suspension, double wishbones all round...
I think that GW "guessed" that the COG axis of a syncro Westy was just about behind the front grille badge, based on their forklift tilt "test". Now that's quite a way off the ground.
Now if someone's got a set of corner weight scales (ideally) or even a c.w. lift gauge to work wheel-to-wheel, then COG could be worked out fairly closely; even if only to advise owners of the safe side slope angle before pushing their luck when off-road, conditions permitting.
It's a public service you know

40 degrees isn't it... haven't you seen the original syncro PR video

What ho Clive! 40 degrees "safe" or "on the limit under optimal conditions"? Panel van or full-loaded Westy?
Now if an enterprising individual had a couple of 3m lengths of 250mm channel, a see-saw could be knocked up for next to nothing to find the fore-aft balance point of individual vehicles...
But that doesn't get anyone any nearer to actually knowing if a suspension lift does actually improve or diminish a syncro's handling, considering the attendant increase in spring rates, changes to anti-roll bar effective lever lengths (if fitted) etc
Anecdotal evidence is all well and good, but I'd like to see some supporting figures before I went a-lifting.
My little donkey is so light on it's feet anyway it doesn't need it

ask this guy at 37 seconds in about the 40 degrees

Ouch. Well he was attacking the hill like a right one.... looks like they had trouble getting the windscreen back in, not very straight after that.

if you watch all the films parts 1-5 it certainly shows you what a beating these vans can take!!!
looking forward to trying a bit myself!!

So I suppose no-one really wants to (or can't) answer the original question then:
What are the effects on the relationship between roll centre and COG and the handling implications resulting from a suspension lift on a T3 syncro?
With relevant numbers, graphs, drawings and data please

If you watch closely - he had the wheel fairly hard over to the left most of the critical time... a straight ahead or bit of right lock when it started jumping up like that, would have easily prevented that rollover. You don't steer against an incipient roll, but into it...
But, I'd better button by bouche, before it bappens to be

Well, you're right. I can't. but I guess you'd have to specify the perimeters. The options are almost infinite... Type of springs, shocks, type of wheels, type of tyre, body type, camper conversion....etc etc.
I guess you would have to ask a more precise question, with relevant numbers, graphs, drawings and data.

It´s not that we don´t want to talk about it we´re just all in denial
