I posted a thread a few months back complaining about the prodigious amount of brake dust that the Z makes on its front wheels. I'm sure this is common sense to most here but I just changed out the front brake pads from stock semi metallic to ceramic and it's been a month and so far, no brake dust. I can actually go a few days after washing the Z and know that my wheels will stay reasonably clean.

So for those out there who have the front brake dust problem, change them out to ceramics. It may cost a little more but it's definitely worth it.
