Product Details

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are engineered as one-piece replacement brake discs for drivers who want a more responsive brake feel without changing the factory brake setup. The slotted X-drilled surface supports heat management, dust evacuation, and pad conditioning, while the coated finish helps the rotor resist corrosion over time. This rotor measures 348.000 mm outside diameter, 30.000 mm nominal thickness, and 28.400 mm discard thickness, with a 79.000 mm center hole diameter and 5-lug mounting pattern.

Compatible With BMW 745i, 745Li, 750i, 750Li, 760i, and 760Li front left applications. This part number, 127.34064L, is a fitment-specific rotor for select BMW 7 Series models from 2002 through 2008.

Common Issues This Rotor Can Address

• Brake fade during repeated stops
• Glazed brake pads that reduce pedal response
• Excess brake dust buildup on the rotor surface
• Corrosion on exposed rotor surfaces
• Uneven braking feel from worn front left rotors

Installation Notes and Tips

Install on the front left position only where listed fitment matches the vehicle. Verify rotor dimensions, hub center bore, bolt circle, and caliper clearance before installation. Because this rotor is a direct replacement for stock brake systems, it should be matched with the correct BMW 7 Series application and inspected alongside pads and related brake components for wear.

Quality Assurance

StopTech designs this rotor line for street use with corrosion-resistant coating and high-carbon construction in most applications to support quieter operation and improved durability. Part number 127.34064L is built to OE-style fitment standards for the listed BMW applications.
