Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors feature a vented design with pillar-style vanes that promote efficient airflow to dissipate heat during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water, improving brake pad contact and reducing fade. The coated hat finish protects the rotor hub from corrosion, ensuring long-term durability. With a floating disc mounting system, these rotors allow slight movement to prevent warping and maintain consistent braking performance. The rotor measures 11.654 inches (296 mm) in diameter with a nominal thickness of 1.024 inches (26 mm), meeting OEM specifications for the listed Chevrolet, Pontiac, and Saturn models. This rotor does not include ABS tone rings or bearings, so it is designed to work with existing vehicle components.

Compatible Vehicles and Applications

• Chevrolet Aura, Cobalt, Malibu
• Pontiac G4, G5, G6, Pursuit
• Saturn Ion, HHR

This rotor is ideal for drivers looking to replace worn or damaged rotors on these specific models, providing improved heat management and braking consistency.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven rotor wear and warping
• Reduced braking performance in wet conditions
• Corrosion on rotor hats leading to premature failure
• Brake noise and vibration due to surface glazing or deposits

Installation Notes and Tips

Ensure the rotor thickness is within the discard limits (minimum 0.906 inches or 23 mm) before installation. Clean the rotor surface to remove any protective coatings or oils. Verify compatibility with your vehicle’s lug pattern (5 lug holes, 0.563 inch diameter) and bolt circle diameter (4.331 inches). Since this rotor does not include bearings or ABS tone rings, reuse existing components as needed. Proper torque specifications should be followed during installation to avoid rotor distortion.
