Sport 1-Piece Drilled/Slotted Rotor

The StopTech 127.34108L is a Sport Drilled and Slotted 1-Piece Front Driver Side Brake Rotor engineered to offer a significant upgrade over stock braking components. Constructed from high-carbon iron with Power Alloy metallurgy, this 1-piece rotor is built for durability and optimal performance. The vented design promotes better heat dissipation, while the drilled holes and slots work together to increase pad bite, improve air circulation, and provide an escape path for heat, dust, gases, and moisture. The slots also help to clean and de-glaze the pad surface, ensuring consistent friction. The rotor is finished with a black e-coat on the hat, inside the cooling vanes, and on the outside edge, offering superior corrosion resistance and a clean look behind the wheels. It features a 312mm diameter, 73.6mm height, and 23.8mm nominal thickness, with a discard thickness of 22.4mm. The hub hole diameter is 79mm, and it has 5 lug holes with a 120mm bolt circle. StopTech notes that nearly all of their 1-piece rotors have unique slot or hole patterns for the left and right sides, utilizing straight vane or pillar vane rotors to ensure drilled holes do not intersect cooling vanes.
