Good info.
1 way you can completely eliminate roll steer in rear setups is to use a very solid, infamous 2link. that's about the only good thing you get out of that damn thing, if you even want to consider it "good"

A wise man once said something about the less movement a suspension is allowed to have the less problems it can cause.
In other words a vehicle with zero travel has no concern about camber, roll centers, toe, squat, dive...

for real i felt like i just sat through a college class really good info but i seriously havent read anything that sounded like that since i was studying theorhetical physics

hold the best part was in the middle of one of grims post mixed in with all the engineering jargon he got all ghetto and said "personally i roll slip drive shaft in to keep the torsoin out of the drive line" for some reason that sentance using the word "roll" in that way seemed way out of place

I see what you are trying to say now.
What you are thinking happens, doesn't. The triangulated bars act more like a wishbone does. The wishbone can not do what you are thinking because it is a triangle and shouldn't change shape to create the situation that you are concerned about. The triangulated bars act the same way. They can not change the shape of it's set triangle (unless the tabs break) to cause the binding you feel happens. The rear end swings around the point set by the trianulated bars the same way a wishbone set-up does. The lower parallel bars are just along for the ride. By changing the angles on the lower bars you can change the roll steer effects. The pinion angle is only slighly effected by all of this.
As for the tabs breaking, I think it is probably a case of an under engineered part. The builder not appreciating the loads placed onto the tab to keep the vehicle from moving front to back and side to side.
Does this all make sence?
[On tabs breaking, I'm sure your 100% right]
Good to know.. At first glance I must admit it was hard for me to visualize working, but upon careful consideration I have to agree with you. It seemed that tension must add the further the triangle point passed the pivot point. For example on a wishbone configuration the point is exactly on the pivot point for rotation. But as one moves to 4 triangulated links, depending on the angles you use, you push that point further from the pivot point (front or rear depending on where your triangle is pointed). It seemed as that occurred the more movement forced on the triangle caused more tension. But I have to agree it really wont matter.
That's a good analogy too. That wishbone analogy makes good sense, I'm really glad I'm wrong on the bars being under tension because I really like the angled design, and the less moving parts for maintenances. Its a detailed problem to reach a solid verdict on, I really appreciate the time and sharing of experience you've passed on here man its helped me a lot.
Awesome topic - & great BS'n with you bro

I really enjoy getting deep into a subject, there just isn't enough room to do it most of the time.
My employee and I were talking about the stresses that a triangulated system might see. We came to the logical conclusion that the less angle the bars have on them, the more stress will be on the tabs (while trying to limit lateral movemnet.) The ideal angle would be 45 deg, but that isn't always possible. I have always just run as much angle as I can squeeze into my confines.
