I never thought of doing that, I guess it makes sense for some axle types - instead of the roll bar keeping both sides of the car level, pressure on one side pushes the other side up. I have real trouble getting my head around the way roll centres etc would work on a solid axle, depending on how much pressure you apply to each side etc :smile:. also from what I gather, roll centre on a solid rear axle is usually somewhere near the centre of the wheel, probably near the diff case - that would help change your handling a bit.you put a anti roll bar on the axle that you want to be non-independent and put it as a negative number, like -5000
In general I think that depends on how it's linked up - there are anti-sway bar geometries that can lower the roll centre quite a bit. In the most basic case it'll be approximately at the height the anti-sway bar attaches (eg. if it links to the bottom of the diff case, that'll be the roll centre). But there are tricks to put it elsewhere. The problem is, the more the driveshaft is above the rollcentre, the more lateral movement it has to make when the car rolls, since it's linked to the wheels.from what I gather, roll centre on a solid rear axle is usually somewhere near the centre of the wheel, probably near the diff case - that would help change your handling a bit.
