Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.40071R) are precision-engineered to meet the braking demands of Acura and Honda SUVs and sedans such as the MDX, Pilot, RLX, and ZDX. These rotors feature a vented design with straight vanes that promote efficient airflow, helping to maintain optimal operating temperatures during heavy braking. The cross-drilled and slotted surface pattern aids in expelling brake dust, gases, and water, which can improve pad bite and reduce brake fade under demanding conditions.

The rotor’s hat is coated to resist corrosion, extending the service life and maintaining a clean appearance. The floating disc mounting system allows for slight movement between the rotor and hat, which helps reduce stress and warping during thermal expansion. With a nominal thickness of 1.102 inches (28.000 mm) and a discard thickness of 1.024 inches (26.000 mm), these rotors provide a balance of durability and performance. The 5-lug hole pattern with a 4.724 inch (120.000 mm) bolt circle diameter ensures proper fitment on compatible Acura and Honda models.
