I've got those adjustable rear arms from DMAX on my car (came with the car) and due to going with a slightly wider rear tyre over the weekend at the back, I now need to run a good few degree's of negative camber in order for the tyres to not bash and eventually crack my rear fibreglass wings. I've shortened the two two blue arms on the hub (the stubby one that bends around the coilover and the straight 'traction bar'?) as much as they will go but doing so barely made a difference. Did I adjust the right things, or will I need to invest in different arms? I suppose the other alternative is to go back to running a 255 section tyre, rather than a 275.
