Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors (128.45084L) feature a vented design with straight vanes that promote consistent airflow, helping to maintain optimal operating temperatures during braking. The cross-drilled surface pattern enhances water and gas evacuation, reducing the risk of brake fade under heavy use. The rotor’s coated hat finish provides corrosion resistance, which is especially beneficial for vehicles exposed to varying weather conditions. With an overall diameter of 296.7 mm (11.681 inches) and a nominal thickness of 28.0 mm (1.102 inches), these rotors meet the precise specifications required for Mazda 6 and CX-5 models. The floating disc mounting system allows for slight movement between the rotor and hub, reducing stress and improving rotor longevity.
