StopTech 126.62002CSL Sport Slotted Cryo Brake Rotor - Front Left

The StopTech 126.62002CSL Sport Slotted Cryo Brake Rotor is a direct OEM-replacement front left disc brake rotor that combines StopTech's proven slotted rotor design with a permanent deep cryogenic treatment for enhanced durability and service life. Engineered for drivers who demand more than a standard replacement rotor but aren't ready for a full big brake kit upgrade, this rotor delivers measurable improvements in braking performance right out of the box.

Cryogenic Treatment:

The cryogenic process is a one-time, computer-controlled stress relief treatment that cycles the rotor from approximately -300°F down to well below freezing, then gradually brings it up to over +300°F, and finally returns it to room temperature over a 24-hour period. This cold-and-heat cycling process permanently realigns the molecular structure of the cast iron disc, reducing residual stress and improving the rotor's resistance to thermal cracking and wear — benefits that last the entire life of the rotor.

Key Features:

• Deep Cryogenic Treatment — Permanently reduces residual stress and improves wear characteristics for extended service life
• Slotted Rotor Surface — Slots help evacuate gases, brake dust, and debris from the pad-to-rotor interface, improving initial bite and wet-weather response
• Symmetric Vane, Split-Core Casting — Promotes uniform heat distribution across the rotor face for consistent braking feel
• Double Disc Ground Friction Surface — Machined to precise tolerances for optimal pad contact and service life
• Black E-Coat Finish — Electro-statically applied corrosion protection on all non-swept surfaces (hat, cooling vanes, outer edge) rated to withstand 400 hours of saltwater exposure
• Direct OE Replacement — Designed to fit factory brake calipers and mounting hardware with no modifications required
• Directional Design — Side-specific left rotor with a unique slot pattern optimized for front-left fitment position

The StopTech Sport Slotted Cryo rotor is an ideal choice for performance street drivers, fleet operators, and emergency vehicle applications where extended rotor service life and consistent stopping power are priorities. The durable black e-coat finish also makes these rotors an attractive complement to aftermarket wheels where the hat and vanes are visible.
