Though they did not say why, now that you mention the drilled rotors that actually makes sense because the air passes through.
I am just about at 10,000 miles and there has been no change in the sound at all. |
damnit , i have my car in dealership from yesterday i hope they would tell me something else.
it makes sense as air passes but cannot travel inside, we might have to complete half the job BMW missed doing
