Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are designed to meet the demands of daily driving and spirited performance on vehicles such as the Chevrolet Cobalt, Pontiac G4, and Saturn Pursuit. Featuring a vented rotor design with straight vanes, these rotors promote efficient heat dissipation to reduce brake fade during extended use. The slotted surface helps channel away dust, gas, and water, maintaining consistent pad contact and improving braking response.

The rotor’s coated hat finish provides corrosion resistance, helping to maintain structural integrity and appearance over time. With a floating disc mounting system, the rotor allows slight movement to accommodate thermal expansion, reducing the risk of warping and uneven wear. The rotor measures 10.079 inches in outside diameter and 1.858 inches in overall height, with a nominal thickness of 0.945 inches, ensuring compatibility with the specified vehicle models.

Compatible Vehicles and Applications

• Chevrolet Cobalt
• Pontiac G4 and G5
• Saturn Ion and Pursuit

This rotor is ideal for addressing common braking issues such as:

• Brake fade caused by overheating during aggressive driving
• Uneven rotor wear and warping from thermal stress
• Reduced braking efficiency due to debris buildup on rotor surface
• Corrosion and rust on rotor hats affecting longevity
• Inconsistent brake pedal feel from rotor distortion

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of rust before installation. Verify the rotor thickness is within nominal specifications and replace if below discard thickness. Use proper torque specifications for lug nuts to avoid rotor distortion. This rotor does not include bearings or ABS tone rings, so confirm compatibility with your vehicle’s braking system components.
