Bluestuff NDX is a high friction sport and race material which is not road legal for EU markets where R90 is required. OK for road use in USA and Asian markets. 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 Bluestuff NDX is their bite from cold and progressive brake feel and the ability to bring a car to a complete stop.
See the new range of EBC Orangestuff grade full race pads which deliver faster bed in and higher temperature thresholds. As with all brake pads selection involves a trade off with life and disc/rotor wear and EBC have chosen with both the Bluestuff and Orange grade race pads to offer a pad that is the replaceable item rather than the disc or rotor. You will find that the EBC product is far kinder to to your brake discs than comparable granite like semi metallics which may last longer but take your rotors with them.
