Description Features: Constructed in two parts, aluminum center and stainless steel braking surface High-performance disc, allowing the stainless steel outer to expand separately from the center and handle high temperatures without warping Hope floating rotors have a true floating design, which allows 1 degree. of freedom. This means the outer is always free to expand when subjected to heat Lightweight design The aluminum center acts as a heat sink, keeping disc temperatures lower CNC machined center is stiff and lightweight, so it has the advantages of a thicker fixed disc without the weight penalty
