Yes the Rover application is far less expensive and affords you other choices of rotors that are more budget friendly. I just happened to stumble across the BMW M calipers that made this an easy upgrade. The unfortunate thing is the 390mm BMW rotors are costly and was by far the most expensive component/s for the upgrade. If I did not have the BMW X5M calipers I would definitely have done the Rover upgrade. This was the path that I was on.
