Bluestuff NDX Super-Street brake pads by EBC have passed extensive road focused testing and gained R90 approval on some E.U. fitments, making it unique in being the first truly track focused pad which is also perfectly legal for use on the public roads across Europe. For users with experience of EBC’s widely acclaimed Yellowstuff material, Bluestuff boasts a similar friction profile but with a usefully higher friction coefficient across the now larger working range. Bluestuff has a high friction coefficient without feeling grabby, taking things up a notch from EBC’s Yellowstuff material by bringing superb pedal modulation to a track pad with even greater fade resistance. However, being a track focused material, users may experience a noticeable increase in both brake dust and brake noise. As is often the case with friction materials, an increase in ultimate performance is often met by an increase in noise and dust.
