I am waiting for the opertunity to align the vehicle myself. I am sure the ‘range’ is quite broad, allows a tech to easily “get it in spec” (red ligh/ green light alignment). You will get a new set of (racing) specs with your New Owner Kit from Ford. I would align closer to those and I have read they require Camber Plates. I would say Camber Plates are necessary if you have plans of aligning the car straight.
