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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance through improved heat management and pad bite. The cross-drilled holes and slots help evacuate gases, dust, and water from the rotor surface, which is critical for maintaining consistent braking in demanding conditions. This product line features vented rotors that promote airflow to reduce thermal buildup, making them suitable for both street and light track use. The coated hat finish adds durability by protecting against corrosion, extending rotor life.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize cooling. The rotor’s overall height measures 68.6 mm (2.701 inches), and it includes a center hole diameter of 60.1 mm (2.366 inches) for precise hub fitment. The rotor weighs approximately 5.91 kg (13 lbs), balancing strength and weight for effective braking without excessive unsprung mass. It does not include ABS tone rings or bearings, so compatibility with your vehicle’s existing components should be verified.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves brake pad cleaning to prevent glazing and extend pad life
• Enhances heat dissipation to maintain consistent braking performance
• Resists corrosion with coated hat finish for longer service life
• Compatible with Toyota Previa and Supra models requiring 291 mm rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (17.0 mm) before installation
• Verify compatibility with vehicle’s lug pattern: 5 lug holes on 114.3 mm bolt circle
• Use proper torque specifications for mounting bolts to avoid warping
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
