I’d be very surprised if they use the carbon-wrapped rotors in the LR. Sharing parts is fine if there is no added cost but wrapping the rotors, as Elon called out, is difficult. Difficulty = cost. The RPM conditions that require the carbon-wrap do not exist in the LR with the lower top speed. They are going to sell more LR’s than plaids so if they use the same motor that is a lot of cost being added unnecessarily. And we know what Elon thinks of unused costs(bye-bye passenger lumbar). I’ll bet a $1 that we will eventually find out that the motors/rotors start out on the same line. They go thru a evaluation to get the best of them(like they do for the performance motors for the 3 and Y) and then take the pick-of-the-litter motors/rotors to a separate line to do the carbon-wrapping. Like what BMW did in the 80’s where they pulled a group of 20 regular 5-series off the line at a time and sent them down the road to be turned into M-5’s
