BLUESTUFF automotive brake pads are made of an extremely durable compound for extensive rally applications. The coefficient of friction oscillates at the level of 0.4 to a temperature of 900 degrees C, the mixture in Bluestuff blocks has 2 to 3 times longer wear time compared to the Yellowstuff series and, similarly to the Yellow and Red series, does not damage the brake discs. As the only one from the ECB's offer, they require prior warming up so that they can brake effectively.
