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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering rotors that combine cross-drilled holes and precision slots to enhance brake pad bite and improve water and gas evacuation. This design helps maintain consistent braking performance during spirited driving or heavy use. The vented rotor construction further aids in heat dissipation, reducing the risk of brake fade. The coated hat finish adds durability by protecting against corrosion, making these rotors suitable for daily driving and performance applications on compatible Fiat and Ram models.

Detailed Product Description

This disc brake rotor features a vented design with pillar-style vanes that promote airflow to cool the rotor during braking. The cross-drilled and slotted surface pattern helps to clear brake dust, gases, and moisture from the pad surface, improving contact and reducing fade. The rotor’s overall height measures 1.720 inches (43.7 mm), with a center hole diameter of 2.323 inches (59.0 mm) and a mounting bolt hole circle diameter of 3.858 inches (98.0 mm). The floating disc mounting system allows for slight rotor movement, which can help reduce stress and improve braking consistency. The rotor does not include ABS tone rings or bearings, so these components must be sourced separately if required.

Common Applications and Problem Solving

• Improves braking performance on Fiat 500 and Ram 700 vehicles
• Reduces brake fade during extended or aggressive braking
• Minimizes rotor warping caused by excessive heat buildup
• Enhances pad bite and braking response in wet conditions
• Protects against corrosion with coated hat finish

Installation Notes and Tips

• Ensure compatibility with Fiat 500 and Ram 700 before installation
• Check rotor thickness and discard thickness to confirm rotor serviceability
• Use proper torque specifications for the 4 stud/lug holes (0.520 inch diameter)
• Inspect brake pads and hardware during rotor replacement
• Floating disc mounting requires correct alignment for optimal performance
