Vee profile improves resistance against warping. The’Vee-Rotor’ features an aggressively styled’wavy’design, with radical new machining techniques making for EBC’s lightest weight rotor profile. Their fully floating design features EBC’s unique and patented S-Drive button system, which use square sided rivets captured in square drive pockets on the rotor and hub allowing the outer rotor the ability to expand and contract freely under the heat of braking without suffering rivet lock – preventing distortion and vibration.
