Yellowstuff have even more fade resistance, dust levels are just the same but, the dust is like transluscent in colour so doesn't look anywhere near as dirty.
I was cleaning my wheels about every week with reds but still worth it, you won't go wrong with either pad, yellows feel more "solid", odd I know but they have slightly and is only slightly less feedback than reds, and do take a 2 or 3 goes of normal stopping to do thier best, but even thier worst is awsome, was going to try blue next, but not road legal!!
I only have std discs sizes at the mo(2wd sapph), make sure you put these all round, as there was 2 days between doing my ones front + rear, and unbalanced the car nicely!!
