oh boy, 3mm is not a lot of clearance... i dont think i'd feel comfortable running such a set up. if your wheel gets just a little out of round from hitting a pothole or curb, you can ruin your BBK so easily....
my own personal wheels have been bent before after hitting a pothole but i was able to drive home and have the wheels repaired without worrying that my brakes were going to get ruined.
but big props to richard for trying out this set up for the rest of us!
