EBC Bluestuff NDX Front Brake Pads for 2006–2009 Audi RS4 4.2 with Cast Iron Rotors, DP51513NDX

Bluestuff NDX is a high friction sport and race material that can be used for aggressive street driving and certain types of track use. The material has had much success on the track with quality aftermarket calipers (Multi piston systems with better release and cooling and larger rotors) and limited success with street based calipers where pad size and caliper drag can challenge any brake material. The biggest advantage of EBC Bluestuff NDX is their bite from cold and progressive brake feel and the ability to bring a car to a complete stop. This has led to the ECE R90 brake safety regulation approval of R90 which is now completed and certificates are being obtained (during July 2011). There are certain older street based caliper systems where even the new Bluestuff will have trouble handling the caliper and slider drag inherent in the systems but this scenario is exactly the same for our competitors. There is NO material that will be PERFECT on the track in all older street based caliper systems. Pad Dimensions: 95 x 75 x 14mm

• Chemical Interlayer Pad For Super Strong Pad Bond
• Deep V Grooves Catches Dirt Dust/Improves Venting
• Huge Lifetime Almost Double Previous EBC Products
• Surfaces Are Left Smooth And Not Scored
• Worlds First Street And True Track Pad
• Low Heat Transfer
• Easy On Rotors
• Great Release

EBC Bluestuff NDX front brake pads are engineered for aggressive street driving and selected track applications on the 2006–2009 Audi RS4 4.2 equipped with cast iron rotors. This high-friction compound delivers strong initial bite when cold, progressive brake feel, and dependable stopping performance during demanding driving. The Bluestuff NDX material is designed to provide the control needed for spirited road use while offering the heat resistance and release characteristics required by many performance-oriented brake systems.

The EBC DP51513NDX pad features a chemical interlayer that promotes a strong bond between the friction material and backing plate. Deep V grooves help capture dust and improve venting, while the smooth, non-scored friction surface is designed to be easy on rotors. Low heat transfer and consistent release can help support predictable pedal response and braking balance. As with any high-performance pad, results may vary on older street-based calipers where slider drag, limited pad area, or caliper release characteristics can affect track performance.

Bluestuff NDX has been developed as a street-and-track brake pad for compatible multi-piston caliper systems with effective cooling and larger rotors. Its high-friction formulation can provide a long service life compared with earlier EBC performance materials, while maintaining confident braking during repeated use. This application is intended for the front axle and is supplied as a set for one vehicle application.
