Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are specifically designed for select Honda models including the Civic, Civic del Sol, and CRX. These rotors feature a vented design with straight vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The slotted surface helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent pad contact and improving overall braking response.

The rotor’s hat is coated to resist corrosion, extending the service life of the part. With a floating disc mounting system and four mounting bolt holes arranged in a 100 mm (3.937 inches) bolt circle diameter, these rotors ensure precise fitment and reliable performance. The rotor measures 240 mm in outside diameter and has a nominal thickness of 21 mm, with a discard thickness of 19 mm, indicating when replacement is necessary to maintain safety and performance.
