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 debris removal. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing gases and dust to escape, while the vented rotor design promotes airflow to keep temperatures down. This product line is suitable for drivers seeking consistent braking response and durability in both street and light track use.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize cooling efficiency. The rotor's overall height measures 53.3 mm (2.098 inches), and it includes two miscellaneous holes for mounting or alignment purposes. The center hole diameter is 60 mm (2.362 inches), and the mounting bolt hole circle diameter is 114.3 mm (4.5 inches), accommodating five lug holes. The rotor surface is coated on the hat area to resist corrosion and extend service life. Note that this rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance in wet conditions by channeling water away
• Minimizes brake dust buildup for cleaner braking surfaces
• Restores braking efficiency on Toyota Supra models with worn or damaged rotors

Installation Notes and Tips

• Ensure compatibility with Toyota Supra models before installation
• Check rotor thickness and discard limits to confirm suitability
• Use proper torque specifications for mounting bolts on the 5-lug pattern
• Inspect brake pads for wear and replace if necessary during rotor installation
• Perform a bed-in procedure after installation to optimize rotor and pad contact
