TRQ Rear Brake Rotor Set G Coated Vented Drilled Slotted - Reliable

Our review of the TRQ Rear Brake Rotor Set covers fit, build, and on-road performance for compatible BMW 525i, 528i and 530i models. In short, this two-piece G-coated rotor set is aimed at owners who want a direct-fit replacement with improved appearance and dependable braking feel without modifying original components. The package includes both driver and passenger rear rotors with pre-assembled features that make installation straightforward, and the G-coating offers corrosion resistance that helps maintain a clean look over time.

Key Features

• Direct-fit design: Pre-assembled components match OE mounting points so installation is quicker and does not require modifications.
• G-coated finish: The coating reduces visible rust and helps keep the rotor face looking cleaner between services.
• Vented, drilled and slotted surface: The rotor pattern supports heat dissipation and may improve wet-weather braking response.
• Complete rear kit: Includes one driver and one passenger rotor so both sides are replaced together for balanced braking.
• Compatibility references provided: Multiple reference numbers and fit notes help confirm vehicle fit before purchase.

Who It's For

This rotor set is best for owners of 2004-2007 BMW 525i and 530i and 2008-2009 BMW 528i who need an economical, direct-replacement rear rotor with improved surface appearance and service-friendly features. Mechanics and DIYers who prefer parts that drop into place and reduce installation time will appreciate the pre-assembled fitment.

Those seeking track-focused components or radical performance upgrades should look elsewhere, since these rotors are designed for street use and direct-fit replacement rather than extreme motorsport demands. Also, buyers should confirm exact fitment against the vehicle mounting bolt circle and center hole dimensions before ordering.
