well another attempt saw them fit relatively easily, seems to help to keep the wheel on during fitment and carefully lower the car to the ground with the new component on but only the control arm nut done up so that the suspension gets slightly loaded then raised back up
awesome difference, almost zero diving under brakes, or lift during acceleration, also seems to help with turn-in response, and regarding power understeer, it feels like the car is actually pulling you out of the corner now rather than into it...noticeable increase in nvh though
