These are all great points. The only negatives seem to be the increased pedal travel until bite and the cost. Oh the third is the hassle of dealing with Tesla service center and their potential incompetence requiring a few back and forth visits, Uber rides, and wasted time.
For me, in addition to the above, I probably won't keep the car more than another 1-2 years. I'm guessing the HW4 FSD itch will bite. Plus newer Plaids have the matrix lights, new tail lights, and movable screen. The resale on the Plaid is terrible, probably depreciates 50% in 2 years. For me the hassle of keeping the old brakes around the garage, unloading them, dealing with selling them, and then selling the car with CCB or stock brakes in 1-2 years has me thinking hmmmmmmm........yes the brakes are much better, but maybe I should just do it next time around when I first get the car.
