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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat dissipation and pad bite. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing gases and debris to escape, while the vented rotor design promotes airflow to keep temperatures in check. This product line is suitable for drivers seeking reliable and consistent braking on Porsche 911, 924, and 944 vehicles.

Technical Specifications and Features

These rotors feature a vented design that improves cooling efficiency during heavy braking. The cross-drilled and slotted surface enhances pad contact and helps remove brake dust and water, contributing to consistent braking performance. The coated hat finish provides corrosion resistance, extending rotor life. The rotor measures 11.122 inches (282.5 mm) in outside diameter with a nominal thickness of 0.787 inches (20 mm), and a discard thickness of 0.752 inches (19.1 mm). It includes 5 mounting bolt holes with a bolt circle diameter of 4.961 inches (126 mm) and a mounting bolt hole diameter of 0.339 inches (8.6 mm). The center hole diameter is 4.213 inches (107 mm), and the rotor mounts behind the hub.

Common Applications and Problem Solving

• Improves brake cooling to reduce fade during spirited driving or track use
• Enhances brake pad bite and responsiveness with slotted and drilled surface
• Helps prevent glazing and buildup of brake dust on pads
• Reduces corrosion with coated hat finish for longer rotor life
• Restores proper rotor thickness and surface condition for safe braking

Installation Notes and Tips

• Ensure compatibility with Porsche 911, 924, and 944 models before installation
• Check rotor thickness and discard thickness to confirm replacement necessity
• Use proper torque specifications on the 5 mounting bolts during installation
• Inspect brake pads and replace if worn to optimize rotor performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
