Product Line Details: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to offer enhanced braking performance through advanced rotor surface technology. The cross-drilled pattern improves ventilation and cooling, which helps maintain consistent braking under demanding conditions. This product line features vented rotors with pillar-style vanes to optimize airflow and reduce heat buildup. The coated hat finish adds durability by protecting against corrosion, making these rotors suitable for both daily driving and spirited use on Mercedes-Benz vehicles.

Technical Specifications and Features

These rotors have a nominal thickness of 0.984 inches (25.000 mm) and a discard thickness of 0.882 inches (22.400 mm), ensuring a long service life before replacement is necessary. The overall height measures 1.831 inches (46.500 mm), and the outside diameter is 11.339 inches (288.000 mm). The rotors are vented with pillar-style vanes to promote efficient heat dissipation. The floating disc mounting design allows for thermal expansion, reducing the risk of warping. The hat is coated to resist corrosion, extending rotor longevity. This rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Reduces brake fade during high-performance or extended braking
