It is a great catalog isn't it? I have not found any other company that releases the kind of great information that wilwood does.

My impression about the dust issue is that if it doesn't say low dust, then it is high dust! That leaves us with Q and T compounds (unless I missed one). Look at the CF graph for the Q pad and you will see that they work better (higher CF) as they get hot.

I just took off the J pads this weekend and put the T back on. I could not live with the amount of dust from the J pads on a day to day basis. In order to come close to the brake torque produced by the J pad with the T pad I have to increase my rotor size from 10.75 to 12.19 and STILL the peddle effort will be slightly higher(all else remaining equal). The Q pad would make up the difference. I think that shows just how much higher friction in a real world, quantitative way, the J pad grip is above the T.

Big brakes make the whole equation easier to solve for a street car, but remember, F1 runs 13" rims! They also have a billion dollar a year budget!
