The amount of dust means little in the grand scheme of things, ALL brake systems have to have a sacraficing component, and will all make at least SOME dust. What does matter is the type of dust, and what exactly gets sacraficed. Metallic pads like OEM emit tiny metallic particles which are sharp, and easily become embedded in damn near anything, making it "stick" to surfaces. Metallic pads also sacrafice rotor material, as well as themselves to create the needed friction to stop- This in turn causes a large amount of metallic dust to be created.
Non-Metallic Pads on the other hand are self sacraficing, and generally do very little to the rotor. The coefficient of friction is the same, though the dust is not metallic, it is organic. Thus it is not as dark, doesnt stick as well, and overall produces less. The downside to organic compounds is their heat handling ability, which is far below that of metallic compounds. The EBC reds are a semi-metallic pad that offers the best of both worlds, a trackable, street friendly pad that produces low dust by nature. What more can you ask for? Are they the best choice for racing? no, but they can handle track days without a problem, and that is far more of a pad than you will ever need on the street... the rest is just a bonus. The only downside to running them REALLY ******* the track is that they wear more quickly at those temperatures than a true track pad designed for that temp range, but in reality, they are a consumable anyway. If you plan on tracking the car often or for extended intervals and want longer pad life, switch to the EBC Yellow pads instead- but as a result you are then going to increase dust again in order to increase the wear interval.
