Why T700 carbon ceramic
-
High strength-to-weight ratio. SBD carbon ceramic rotors use only T700 carbon fiber (~4900 MPa tensile strength, ~230 GPa modulus) — roughly 40% higher tensile strength than T300-based rotors.
-
Superior thermal resistance. Stable at operating temperatures over 1000C; typical SBD rotor temperature stays around 500C even in intensive street use.
-
Improved heat dissipation. A directional vane design gives a 5-10% faster cooling rate from 500C than competitors.
-
Exceptional durability. 3-5x the life of conventional iron rotors; over 350,000 miles of normal use. Tested to 7000 rpm wheel speed (equivalent to 300 mph) without damage.
-
Corrosion resistance. 480-hour continuous 5% NaCl salt spray test at 35C with no surface or weight change.
-
Noise and vibration damping for a quieter, smoother braking experience.
-
Consistent friction coefficient across temperature ranges for predictable pedal feel.
Rotors are priced in 2 pieces (1 pair) or as a complete set of 4 pieces.
Note: There are serial numbers on the rotors — install the rotor rotation properly as they have directional vanes. An odd serial number means the driver side; an even number means the passenger side.
