Performance Machine Spoke Mount Rotors are CNC precision ground to ensure a flat and parallel surface. Hardened 420 stainless steel disc meets RC36 specifications. Semi-floating design yields a rotor with a higher resistance to wear, warping and rotor deformation. The wave cut braking surface is drilled in a sweep pattern for optimal heat dissipation with a reduction in weight.
