These rotors provide enhanced braking performance through a combination of cross-drilled holes and precision slots designed to improve heat dissipation and maintain consistent pad contact.

• Cross-drilled and slotted surface for improved heat dissipation and brake pad cleaning
• Solid rotor design with a coated hat finish for corrosion resistance
• Nominal thickness of 0.472 inches (12.000 mm) with discard thickness at 0.394 inches (10.000 mm)
• Overall diameter of 11.811 inches (300.000 mm) suitable for specified Audi models
• Floating disc mounting with 5 lug holes and a mounting bolt hole circle diameter of 4.409 inches (112.000 mm)

Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to meet the demands of both street and light track use for Audi vehicles such as the A4 Quattro and Q5. The solid rotor construction provides structural integrity while the cross-drilled holes and slots help to reduce brake fade by allowing gases and debris to escape, maintaining optimal friction between the rotor and brake pads. The coated hat finish protects against corrosion, extending the rotor's service life. With an overall height of 1.417 inches (36.000 mm) and a center hole diameter of 2.677 inches (68.000 mm), these rotors are engineered for precise fitment and reliable performance.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering enhanced braking performance through advanced rotor surface technology. This product line combines cross-drilled holes and slots to improve cooling and pad bite, which is particularly beneficial for Audi models that require consistent braking under varied driving conditions. The solid rotor design with a coated hat finish balances durability and corrosion resistance, making it a practical upgrade for drivers seeking improved brake response without compromising rotor longevity.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup on pads and rotors
• Enhances overall brake system cooling to extend component life
• Addresses uneven pad wear caused by heat spots

Installation Notes and Tips

• Compatible with Audi A4, A5, A6, A7, and Q5 models as specified; verify fitment before installation
• Ensure rotor thickness is above discard thickness (0.394 inches) before installation
• Use proper torque specifications for the 5 lug/stud holes (0.602 inch diameter)
• Check for ABS sensor clearance as this rotor does not include an ABS tone ring
• Inspect brake pads and calipers during rotor replacement for optimal performance
