Description
Frozen Rotors® Slotted brake rotors are designed to improve braking performance, deliver consistent stopping power, and enhance brake response. Precision CNC-machined slots help reduce brake fade caused by gas buildup between the brake pads and rotor surface while cleaning and refreshing the pad contact area for improved braking bite.
The slots are machined to the rotor's discard depth, providing a convenient wear indicator. When the slots are no longer visible, it indicates that the rotor has reached its replacement point.
Slotted rotors also improve wet-weather braking by creating channels for water to escape from the braking surface. Recommended for performance vehicles and demanding driving conditions, they provide improved braking confidence and stopping response.
