Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and precision slots. This design improves brake pad bite and helps evacuate gases, dust, and water from the rotor surface. The vented construction with pillar-style vanes enhances airflow to maintain optimal operating temperatures, reducing the risk of brake fade during demanding driving conditions. The coated hat finish provides corrosion resistance, making these rotors suitable for daily driving and spirited use on compatible Chevrolet, Pontiac, and Saturn models.

Detailed Product Description

These StopTech rotors feature a vented design with pillar-style vanes that promote efficient heat dissipation, critical for maintaining braking performance under load. The cross-drilled and slotted surface improves pad contact and helps clear debris, moisture, and gases generated during braking. The floating disc mounting system allows slight rotor movement to reduce stress and minimize warping over time. With a coated hat finish, the rotor resists rust and corrosion, extending service life. 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 vehicle applications.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping and vibration
• Enhances pad bite and overall stopping power
• Prevents corrosion on rotor hats for longer durability

Installation Notes and Tips

• Ensure compatibility with Chevrolet Aura, Cobalt, Malibu; Pontiac G4, G5, G6, Pursuit; Saturn Ion, HHR before installation
• Check rotor discard thickness of 0.906 inches (23 mm) to determine replacement timing
• Use proper torque specifications on the 5 lug bolts (14.3 mm diameter) to avoid rotor damage
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Floating disc mounting requires correct alignment to prevent uneven wear
