Detailed Product Features and Specifications

This StopTech rotor features a nominal thickness of 0.709 inches (18.000 mm) and a discard thickness of 0.630 inches (16.000 mm), ensuring a durable braking surface that meets OEM standards. The rotor's outside diameter measures 12.283 inches (312.000 mm), with an overall height of 2.681 inches (68.100 mm). The vented design incorporates straight vanes to promote airflow and reduce heat buildup during heavy braking. The rotor does not include an ABS tone ring or bearings, so these components must be sourced separately if required.

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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves pad bite and helps evacuate gases and debris from the rotor surface, which is especially beneficial for vehicles used in demanding driving conditions. The coated hat finish adds corrosion resistance, making these rotors suitable for both daily driving and spirited use on Lexus and Toyota SUVs.

Applications and Problem Solving

• Reduces brake fade during extended downhill or towing conditions
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner rotor and pad contact
• Helps prevent glazing and uneven pad wear
• Enhances overall braking response and pedal feel on Lexus GX470 and Toyota 4Runner

Installation Notes and Tips

• Ensure rotor discard thickness is not exceeded before installation
• Use proper torque specifications for the six lug/stud bolts (0.571 inch diameter)
• Inspect brake pads and replace if worn to maintain optimal rotor performance
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check compatibility with vehicle ABS systems as this rotor does not include an ABS tone ring
