Product Details

StopTech Sport Rotors are offered with optional cryogenic treatment, a one-time deep-freeze process used to improve wear characteristics in metal components. For fleet and high-use vehicles, that treatment is valued for helping extend rotor service life. The rotor’s vented design, straight vanes, and cross-drilled/slotted face support consistent brake performance under repeated stops, while the coated hat finish helps protect the non-friction surface.

This part number 127.44160CL is a direct-fit style rotor for the front left side on the listed Corolla, xD, Matrix, and Vibe applications. It is a practical choice when replacing a worn rotor on a Toyota Corolla front left brake repair or a Scion xD front left disc brake service.

Common Reasons to Replace

• Brake pulsation from rotor thickness variation
• Visible scoring, cracking, or heat checking on the rotor face
• Reduced braking consistency during repeated stops
• Rotor wear reaching discard thickness
• Corrosion on the hat or non-friction surfaces

Installation Notes

Verify rotor dimensions, bolt circle, center hole diameter, and front left position before installation. Clean the friction surfaces before service and inspect pads, caliper hardware, and hub condition at the same time. This rotor does not include ABS tone ring or bearings.

Quality Assurance

StopTech manufactures performance brake components for street and sport use, and the cryo-treated option is offered as a durability-focused upgrade for this rotor line. Part number 127.44160CL is built to the published specifications for the listed vehicle applications.
