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. Deep V grooves help venting and catch dirt, dust and debris. Notice the open granular surface texture after the heat scorch (pre-bedding) process. Pad shown is a European 4x4 which features balance weights for noise reduction. The NDX pad material is bonded to the steel backing plates using multiple high strength interlock holes and a unique chemical interlayer which raises shear and bond strength by a factor of five and prevents pad to plate separation. The pads are then baked and ground and feature high volume Vee grooves to catch the inevitable large amount of debris from track use. Â
Target use is all types of fast and heavier cars in performance and race driving with much enhanced lifetime over our previous Yellowstuff grade pads.
