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, which is critical during aggressive driving or track use. This rotor line is engineered to provide consistent pedal feel and reliable stopping power for vehicles like the Scion tC.

Technical Specifications and Features

This rotor is a solid type, not vented, which suits specific braking setups requiring a robust and straightforward design. The coated hat finish protects against corrosion, extending rotor life. The rotor measures 279 mm in outside diameter and 42.3 mm in overall height, with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, ensuring clear service limits for maintenance. The rotor mounts using a floating disc mounting system with a 114.3 mm bolt circle diameter and five lug holes sized at 14.3 mm, matching the Scion tC's factory specifications.

Common Applications and Problem Solving

• Improves heat dissipation to reduce brake fade during spirited driving
• Helps maintain consistent braking performance under heavy use
• Reduces brake dust and gas buildup for cleaner rotor surface
• Addresses rotor corrosion with coated hat finish
• Compatible replacement for worn or damaged rotors on Scion tC

Installation Notes and Tips

• Ensure compatibility with Scion tC before installation
• Check rotor thickness and discard limits during installation
• Use proper torque specifications for lug nuts (14.3 mm lug hole diameter)
• Inspect brake pads for wear and replace if necessary
• Follow manufacturer guidelines for bedding-in new rotors
