I had Porterfields on a previous car when I beefed up the brakes and clutch. Low brake dust was a VERY welcome change. Don't let that brake dust sit on the car for too long, particularly in the hot sun. it will eat right through the clear coat. Strip the wheels with a Dawn type liquid or a dedicated wheel cleaner like P21s each time you wash. And don't spend too much time coating them with wax, brake dust cuts right through that.
