When I think of brake pads, I think about braking, which is the primary role of the braking system.
Your life is probably more important than whether your wheels get dusty...if not, maybe the life of your passengers...maybe that innocent child running across the street to get his ball?
Dust should not be on the list of 'qualities for a brake pad.'
You live in Detroit, OP...I'm pretty sure you want a brake pad that will stop you...in rain, snow, sleet...hot and cold.
My set up--balo blanks and OE (textar) pads--five years ago new on all four corners. 60K miles later, I only needed to replace front pads.
60K miles. In a manual, but still. 60K miles of OE bmw stopping power.
Dusting is not a characteristic you should consider for brakes; stopping is.
Upcoming NYC dates: Jan 8 and 27. See Facebook for other shows and PM me if you can make one...love to see you there!
Mangofy your E46!
