Technical Details and Specifications

This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking. The drilled and slotted surface helps to dissipate gases and debris, maintaining consistent pad contact and reducing brake fade. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, the rotor ensures reliable service life and safety. The rotor’s 328 mm outside diameter and 61 mm height are tailored to fit the braking system specifications of BMW 750iL and Z8 models. The 5-bolt hole pattern with a 120 mm bolt circle diameter and 14.7 mm bolt hole diameter ensures precise fitment and secure mounting.

Applications and Problem Solving

• Compatible with BMW 750iL and Z8 models requiring vented, drilled, and slotted rotors
• Addresses brake fade caused by excessive heat during aggressive driving or towing
• Helps reduce brake dust buildup and improves pad bite consistency
• Minimizes corrosion with rust-resistant zinc silver hat finish
• Improves water and debris evacuation with directional surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.4 mm before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify the 5-lug bolt pattern and 120 mm bolt circle diameter match your vehicle’s hub specifications. Directional rotors must be installed following the indicated rotation direction for optimal performance. Use proper torque specifications on lug nuts to avoid rotor warping.
