Features1Design of the floating buckle makes the outer disc not directly locked with the hub, leaving room for expansion; the five-hole 75 Degree fixed connection design, the most stable form of force, can avoid the longitudinal expansion of the high temperature brake disc during braking vibration. 2Frame aviation aluminum alloy has good hardness, toughness, metal anodizing, corrosion resistance, strengthened angle design, and has better tensile and shock absorption. 3Outer frame is made of stainless steel with a hardness of 3842 Degree, which has good wear resistance, toughness, corrosion resistance, tensile strength and resistance to deformation. 4Unique embedded design of the 203mm / 8in disc, the concaveconvex fit between the disc and the hub interface, with a high degree of cohesion and more humaneness. 5After the heat treatment process, the heat sink is in continuous contact with the outer frame, which is equivalent to a radiator, and the heat can be quickly dissipated. 6Newly upgraded precision polishing process, the surface is plated with titanium, the corrosion resistance is good, the strength is improved, and it is more highend. 7Mechanical buoyancy dynamics design, the appropriate force angle, enlarge the hollow part to reduce the weight, and remove the silt faster.SpecificationItem Type: Disc Brake RotorMaterial: Aluminum Alloy + Stainless Steel + Surface Coating TitaniumSix Nails Diagonal Hole Distance : Approx. 44mm / 1.7inPackage List1 x TitaniumPlatedCoolingDiscBrakeRotor
