• Vented rotor design with pillar-style vanes for efficient heat dissipation
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better rotor alignment and reduced warping
• Compatible with Subaru Impreza and Toyota 86/BRZ with 5-lug bolt pattern
• Nominal thickness of 30.000 mm and discard thickness of 28.000 mm
• Outside diameter of 326.000 mm (12.835 inches) for precise fitment

Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to meet the demands of performance-oriented drivers of Subaru and Toyota vehicles such as the Impreza, 86, and BRZ. Featuring a vented rotor construction with pillar-style vanes, these rotors efficiently dissipate heat generated during braking, reducing the risk of brake fade under heavy use. The cross-drilled and slotted surface enhances pad bite and helps evacuate gases, dust, and water from the braking surface, maintaining consistent stopping power.

The rotor’s coated hat finish provides corrosion resistance, helping maintain structural integrity and appearance over time. With a floating disc mounting design, the rotor allows for slight movement to reduce stress and warping, which contributes to longer rotor life and improved braking performance. The rotor measures 326 mm in outside diameter with a nominal thickness of 30 mm and a discard thickness of 28 mm, ensuring compatibility with specified Subaru and Toyota models.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping and uneven pad wear
• Enhances heat dissipation for prolonged brake component life
• Prevents corrosion on the rotor hat for durability

Installation Notes and Tips

• Compatible with Subaru Impreza and Toyota 86/BRZ models featuring a 5-lug bolt pattern and 100 mm bolt circle diameter
• Ensure rotor thickness is above discard thickness (28.000 mm) before installation
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
• Recommended to replace brake pads when installing new rotors for optimal performance
