I have used LRB Z pads and DP 918's on My prior RK and the present SEEG. Both are light years better than stock. Dust goes away. Best thing about the LRB's is the family that sells them. I had a problem with my pads being unevenly worn. I talked to them at Daytona in March and he told me to clean my pistons and the pads would wear evenly, then he reached under the counter and gave me two sets of pads to replace the worn pads, even though it was not his fault they had worn crooked. I took calipers apart and cleaned the pistons and wear evened out. Now I have HHI 6 pistons and intend to change to LRB pads over Christmas. The color change on the rotors easily cleans up with any good brake dust remover... Mothers All Wheel, Meguairs, A-Z etc, the dark color runs right off and rotors look like new.
Good Guy.
