Centric 320.34093F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.34093F, is a front vented rotor built for BMW applications that need consistent braking performance and corrosion-resistant surface protection. It is fully coated on the disc and coated on the hat to help maintain a cleaner finish in demanding driving conditions.

Compatible with select BMW 335i, 335i xDrive, 335is, 335d, 335xi, and X1 front brake applications, this rotor is sized for larger performance-oriented brake systems. The 320.34093F is a direct-fit option for drivers replacing worn front rotors on BMW 335i front brake systems and BMW X1 front brake systems.

Product Details

Centric GCX Elemental Protection Disc Brake Rotors are built around corrosion protection and stable rotor geometry. This rotor uses a vented, straight-vane construction to support heat management during repeated stops, while the fully coated disc and coated hat help protect exposed surfaces from rust. The 348 mm outside diameter, 29.9 mm nominal thickness, and 73.3 mm overall height match the specifications needed for the listed BMW front brake applications. Part number 320.34093F is a practical replacement choice when servicing BMW 335i front rotors or BMW X1 front rotors.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking consistency from heat buildup in the front brake system
• Surface rust on exposed rotor areas
• Noise or vibration associated with worn front rotors
• Service replacement for BMW front brake maintenance

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. Inspect brake pads, caliper hardware, and hub condition at the same time, since uneven wear or corrosion can affect rotor performance. Clean the hub mounting surface thoroughly so the floating rotor seats evenly and the brake system can be torqued to specification.
