Offered for the first time for ATV's, Streamline's NEW Floater Series Brake rotors utilize a 2-piece design which allow radial growth that eliminates warping due to heat. The Streamline Floater Rotors are made up of a stainless steel outer disc and a billet aluminum center hub which are fastened together using our TECH 5 rivet system. Streamline Floaters are made from high grade stainless steel, laser cut, heat treated, and surfaced ground for exceptional flatness.
