Quick FYI for anyone with 16+ LC. As you have noticed the upgraded brakes are really good and dusty at the same time. I have 13k on my 16LC and rotors needed to be resurfaced as steering wheel was shaking left and right at high speed braking. To my surprise, the dealer has just called me if I want to replace brake pads as well (not covered under warranty) as they are down to 50%. Uneven rotors may have contributed, but looks like brake pads are extremely soft (like on BMWs) and have a short life spam of probably no more than 30K if you go easier on brakes than me. Thankfully no additional labor cost since they are working on rotors already, so just need to pay $80 for brake pads.
