For model year 2003 to 2006. A two-piece floating rotor to work with the OE calipers and braking system! Made from High Carbon Alloy with copper and molybdenum for high temperature strength and stability Vanes (all 47) are turned on both ID and OD surfaces to reduce thermal warping and vibration. Runout is less than 0.0005" and thickness variation less than 0.0002" to reduce pulsing and vibration Surface finish is less than 0.7 microns. Has double-shear bobbin attachment to allow both radial and axial expansion. Higher precision and tolerances give you a rotor that will reduce drag, eliminate pulsation and vibration, and reduce heat transfer. And, wear is decreased as well! Lighter that the OE disc (around two pounds per rotor) for improved unsprung weight with a dimpled finish that performs similar to slotted discs but without the wear. No rattling - 100% silent operation. Price EXCLUDES delivery.
