All of our rotors are 2-pcs with removable alloy hats. Full-floating is mainly for race but can be used for streets. They have "H Style" fasteners and anti-rattle plates so they do not make any noise. They will reduce pad drag and wear, heat, and will also reduce all chances of warping, under an extreme track use, with provided radial and axial float. The rotors will be able to expand and contract freely as opposed to the semi-floating 2-pcs.
