ive got the ferodo pads with my r32 front brakes.
in my book stock pads are very dusty, the ferodos aren't so.
Now i bought the car, 0 miles then put the r32 brakes and ferodo pads on within 20 or so miles. I havent run r32 brakes with stock pads, so i couldnt properly comment on dust with this.
But, i would say, i dont have a dust problem with my set up!
and they stop incredibly!!
put it this way....ive been driving a C63 all afternoon with mahoosive brakes (stock pads i would guess) and the brakes on that felt nowhere near as sharp, and im not romancing!!
