Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors feature a vented rotor design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The slotted surface helps to evacuate gases, dust, and water from the pad surface, improving braking consistency and reducing the risk of brake fade. The rotor's hat is coated to resist corrosion, extending the rotor's service life. With a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.787 inches (20.000 mm), these rotors maintain structural integrity and performance throughout their lifespan. The floating disc mounting system and 5-lug hole pattern with a 4.5-inch bolt circle diameter ensure proper fitment and secure installation on Mazda MX-5 and MX-5 Miata vehicles.
