Rear Suspension Movement

The video was taken in a heavily loaded right hand corner, the trailing links do move at slightly inverted paths so stiffer bushings might create bind.

You can stiffen the torsion beam AKA B-Spec Mazda 2 rear ARB, it will create some bind during compression/bump, but will also toe it out and possibly create good oversteer.

Yeah I figured that out after viewing it a second time ;)

Also figured the bushings and the angle of the bolts are what control the toe-out already built into the yaris. If you run a stiffer bushing you will see some bind, but maybe the toe-out will be more linear. In my stock yaris it feels like no toe, no toe, LOTS OF TOE! when doing steady state corners. I think the sudden toe change is also what makes the yaris sensitive to fast changes of load (fast slaloms). That being said, the bind might make the car completely uncontrollable in rear.

You might be able to just rotate the OE bushings to get the results you want. They are directional I would have to look at where the bushings are stiff and where they are open. I think someone should try stiff bushings if it hasn't been done yet.....

My end goal is not to run stiffer bushings but I'm going to keep the cards close to my chest for right now.
