This product line balances durability and performance, making it suitable for Ford Mustang owners seeking improved braking without compromising rotor longevity.

Detailed Product Description

This disc brake rotor is specifically engineered for Ford Mustang vehicles requiring a 5-lug wheel configuration. The rotor measures 12.425 inches (315.6 mm) in outside diameter and features a vented design with straight vanes to optimize heat dissipation during braking. The slotted and drilled surface enhances pad cleaning and gas evacuation, which helps maintain consistent braking performance. The coated hat finish protects against corrosion, extending the rotor's service life. The floating disc mounting system allows for slight rotor movement, reducing the risk of warping and improving overall brake system reliability.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping caused by heat buildup
• Enhances pad bite and braking consistency
• Prevents corrosion on rotor hats for longer service intervals

Installation Notes and Tips

• Ensure compatibility with Ford Mustang models featuring 5-lug wheels and matching bolt circle diameter (114.3 mm)
• Check rotor thickness before installation; discard thickness is 1.118 inches (28.4 mm)
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Break in new rotors according to manufacturer recommendations to ensure proper bedding
