Product Details
StopTech Sport Slotted Disc Brake Rotors are engineered for factory-style fitment while adding performance-focused slotting to the braking surface. The slots help reduce glazing, clear dust, and manage heat buildup, which can improve pedal feel and maintain consistent friction under repeated stops. With a 10.079-inch outside diameter, 0.945-inch nominal thickness, and floating disc mounting, this rotor is built around the specifications needed for the listed Chevrolet Cobalt, Saturn Ion, Pontiac G4, Pontiac Pursuit, and Pontiac G5 front left applications. The part number 126.62072SL is a practical upgrade for drivers replacing worn OE-style rotors without changing the stock caliper setup.
StopTech’s Sport Slotted Disc Brake Rotors line focuses on direct replacement performance parts that retain everyday drivability while adding slotting and corrosion protection. For shoppers comparing brake rotor options for a Chevrolet Cobalt front left rotor or Pontiac G5 front left brake rotor, this line offers a straightforward OE-style solution with performance-oriented surface treatment.
Common Problems This Rotor Can Address
- Brake pad glazing from repeated heat cycles
- Dust buildup on the rotor face
