The Bluestuff NDX race formula is an ultra high friction race pad with a friction level peaking above 0.6 under braking that will generate more G force than most pads out there if not all.NDX is capable of street use as it bites well from cold. The big advantage of this pad is that it is one of the worlds first and only out of the box pre bedded race pads that is surface heat seared or scorched at the factory. This gives amazing reductions in pad bed in time on street or track. Also being a non metallic aramid base NDX reduces rotor wear and eliminates the firework display spark emitted in high speed braking by competitive semi metallics although NDX is not a low dust pad. There is an amount of dust with these pads. Rotor wear is however drastically reduced and pad life enhanced. Rotors wear smooth and flat without ridges.
