Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors (128.40071R) are precision-engineered vented rotors featuring a cross-drilled surface type that helps to dissipate heat more effectively during braking. The vented design with straight vanes improves airflow, reducing the risk of brake fade under demanding conditions. The rotor’s hat is coated to resist corrosion, extending the service life of the part. With a floating disc mounting system, these rotors allow for slight movement to maintain optimal contact with brake pads, enhancing braking consistency.

Key dimensions include an outside diameter of 12.992 inches (330 mm), a nominal thickness of 1.102 inches (28 mm), and an overall height of 1.862 inches (47.3 mm). The rotor features a 5-lug hole pattern with a bolt circle diameter of 4.724 inches (120 mm) and a center hole diameter of 2.760 inches (70.1 mm). Weighing approximately 22.55 lbs (10.25 kgs), this rotor balances durability and performance for Acura and Honda vehicles.
