ST65/28-28-34/35

Performance Rotor Rings 309mm x 32mm (12.17" x 1.26") - P.C.D. 177.8mm. Includes hardware. Paragon Performance Rotor Ring for track/race applications. Features directional ventilation vanes for improved heat dissipation and cracking resistance. Made of CM-250 high carbon alloy cast iron for optimal bite and durability. Heat-treated and CBN surface machined for stress release and better break-in. Lateral run-out within 0.03mm, balanced within 2 grams. Floating 2-piece design minimizes deformation and ensures self-centering. Slotted rotor improves braking consistency and dissipates heat/gases. Superior in wet conditions by preventing water films. Lighter than most O.E. rotors, saving unsprung mass. Includes one pair (LH & RH) and installation manual.
