Thank you

I just looked into my car order. There stays: "Front/Rear brakes 20" (or something similar)
I suppose that it's meant that 20 inch brake discs are mounted.
There is nothing written about the caliper but I suppose there are again 6 pot calipers based on the size of them Range Rover Sport HST D350

I have a D300. Not sure if the front callipers are 6-pot, but they sure are massive compared to the rears.

Interesting aside: I have owned 4 German cars: 3 X5s and a Golf. All of them deposited copious amounts of brake dust on the wheels, especially the fronts. Not so with the RRS. After an 800km trip, there was barely any dust, and that was after a significant distance in the mountains, with obviously much braking. MY21.5 HSE 221KW D16
