just blew a trye on the vs need advice on rolling gaurds and new tyres

As above its to do with the panhard rod is why the diff moves. When you hit a speed bump for instance, the two rear wheels push up into the gaurds. But they dont travel straight up and down either. They go up and push to the left. Its to do with how they are connected to the car chasis. The panhard rod does the connecting to the chassis bit. Its attached to the undercarraige of the car on the drivers side, and then runs across and attachs to the axle on the passenger side. So as the axle lifts and gets closer to the chasis, the panhard rod tends to push the wheels to one side also. You'll have to stick ur head under the back of the var and look at it.

So what happens at the factory they set the axle up so it sits all nice and centered(which centers the wheels inside the wheel arch) at stock ride height. As soon as you drop or raise the ride height, add bigger wheels with different offsets, it throws all this out. The only way to correct it is to put stock wheels back on or by an adjustable panhard rod so you can shift the diff to a new location thats gonna suit your new setup.
