The EBC Bluestuff NDX front pads for 2006–2009 Audi RS4 4.2 (cast iron rotors) are a high-friction sport and race compound that offers strong cold bite and progressive feel for aggressive street and certain track use. Bluestuff provides low heat transfer and smooth release, with deep grooves to improve venting and debris control. These pads suit multi-piston calipers and large-rotor setups where track-capable stopping is required.
