TRQ Rear Brake Rotors Set Vented Premium G-Coated - OEM Fit

In this review the TRQ rear brake rotors set is evaluated as a direct-fit replacement for BMW X3 (2011-17) and X4 (2015-18) owners who want an affordable, OE-style rotor with enhanced surface protection. The bottom line: this 2 piece, vented rotor kit offers straightforward installation and good rust resistance thanks to the premium G-coating, making it a practical choice for drivers replacing worn rear discs without upgrading to a performance rotor. It is best for owners seeking value and compatibility rather than track-focused braking.

Key Features

• Direct Fit: The rotors are designed as an OE replacement for rear driver and passenger sides, so they fit without modification on the specified BMW models.
• G-Coated Surface: The premium G-coating helps resist surface rust during storage and initial use, keeping the rotor appearance cleaner between services.
• Vented Construction: The vented disc design supports heat dissipation under normal driving conditions, which helps maintain consistent braking feel.
• Complete 2 Piece Kit: The set includes both left and right rear rotors, allowing homeowners or mechanics to replace both sides at once for balanced performance.
• OE Replacement Dimensions: The rotors match vehicle-specific mounting and thickness specifications to preserve factory clearances and brake geometry.

Who It's For

The TRQ rear rotors are aimed at BMW X3 and X4 owners who need a reliable, budget-friendly replacement that mirrors factory fit and function; they are a good choice for routine maintenance, daily drivers, and DIYers who prefer parts that install without machining. The included G-coating addresses a common owner concern about surface rust and keeps replacements looking better during storage.

Owners looking for high-performance or track-grade rotors, specialty coatings beyond standard G-coating, or upgraded heat capacity for heavy towing should look elsewhere. This kit is not presented as a performance upgrade, but as a solid, value-oriented OE replacement.

Pros & Cons

Pros

• Direct-fit OE replacement that simplifies installation and preserves factory geometry.
• Premium G-coating reduces initial surface rust and helps maintain appearance.
• Vented design provides adequate heat dissipation for normal street driving.
• Sold as a two-piece kit so both rear rotor sides are matched and replaced together.

Cons

• Not a performance rotor; some drivers seeking improved braking feel or heavy-duty use may require upgraded options.
• Customer reports on braking performance and installation experience are mixed, so professional fitment may be preferred for first-time DIY installers.

Our Verdict
