Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.47024L) features a vented rotor design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall braking response. The rotor’s coated hat finish offers protection against rust and corrosion, extending the rotor’s service life. Designed with a floating disc mounting system, this rotor allows for slight movement to reduce stress and improve alignment, which can contribute to smoother braking performance.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping caused by excessive heat
• Helps maintain consistent brake pad contact for smoother stops
• Prevents corrosion on the rotor hat for longer durability

Installation Notes and Tips

• Compatible with Subaru Forester, Legacy, and Outback models; verify fitment before installation
• Ensure rotor discard thickness of 28.0 mm is not exceeded to maintain safety
• Use proper torque specifications for the 5 lug holes with 13.1 mm diameter
• Check for ABS tone ring compatibility as this rotor does not include one
• Inspect brake pads and hardware during rotor replacement for optimal performance
