Product Details and Specifications

This vented disc brake rotor features a smooth surface type that supports even pad wear and braking efficiency. The nominal thickness of 0.783 inches (19.9 mm) and discard thickness of 0.709 inches (18.0 mm) define the usable rotor life before replacement is necessary. The rotor’s overall height is 2.646 inches (67.2 mm), and it has an outside diameter of 11.457 inches (291.0 mm), matching the precise fitment requirements for Porsche Boxster models. The rotor includes five stud/lug holes with a diameter of 0.606 inches (15.4 mm) and a mounting bolt hole circle diameter of 130 mm (5.118 inches), ensuring proper alignment and secure installation. The straight vane style promotes effective heat dissipation during braking, reducing the risk of brake fade under normal driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below discard limits to maintain braking safety
• Resolving uneven brake pad wear due to rotor surface imperfections
• Improving heat dissipation to prevent brake fade during extended use
• Ensuring proper rotor fitment for Porsche Boxster brake system maintenance

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface and hub mounting area to prevent vibration and noise
