Ok... I just bought a set of Brmbo X-drilled rotors (coated silver) and KVR pads. I know that they need to be break in to prevent likely future damages, but what's the right way to do so?

Since no ones anwering you I will do my best. I have read that you are supposed to first do like 3 gradual stops from
30-0 MPH. Then just drive normall and try to avoid jaming the brakes on for atleast 300 miles.

Emax95 is right but I recommend going to a parking lot to wear in your brakes by running at 5 to 10 mph and avoid hard braking. Do this for about 15 minutes. You don't want to cause hot spots to form on the surface of your rotors. I have cross-drills and was easy on them for the first week. I drive normally with them now.
