I'm running EBC Yellowstuff up front for both DD/HPDE work. All of the more aggressive EBC's take some serious work to bed-in properly, before they are ready for track use. Performance is sufficient for HPDE (on street tires, with stock suspension...), with no instances of absolute loss of performance, although the binders felt a bit wishy-washy on track, never scary, or incompetent, but not race pad-like feel by any means, but equally competent to OEM for street work where a race pad wouldnt be. Operating range is huge, and usually after one light tap on the brakes, are ready to go. They are a bit more rotor intensive than an OEM pad, but nowhere near the level of a true endurance/race pad. Noise is comparable to stock BMW pads, with intermittent squealing during low speed, low brake torque application, but otherwise, smooth and silent. Cheap too.
