TRQ Rear Brake Rotors Set Vented Premium G-Coated - CX-9 Fit

In this review of the TRQ Rear Brake Rotors Set Vented Premium G-Coated, the bottom line is simple: this two-piece rear rotor kit is aimed at Mazda CX-9 owners who need a direct OE-style replacement without paying for dealer parts. The reviewer found it to be a straightforward, vehicle-specific fit that restores rear braking components with a corrosion-resistant coating. Installation and braking feel drew mixed user comments, but for those prioritizing correct fitment and rust resistance at a reasonable price, this kit is the most compelling reason to buy.

Key Features

• Direct Fit: Designed as an OE replacement so the rotors mount without modification to the 2007-15 Mazda CX-9 rear hubs.
• Complete Rear Kit: Includes one rear driver side and one rear passenger side rotor so both sides can be serviced together for balanced braking.
• Premium G-Coating: A corrosion-resistant coating reduces visible surface rust during storage and initial use, helping maintain appearance.
• Vented Design: The vented, drum-in-hat style promotes heat dissipation under normal driving loads to help reduce fade on prolonged stops.
• Vehicle Specific Fitment: Listing notes to check fitment for the 2007-2015 CX-9, which helps ensure compatibility before purchase.

Who It's For

The TRQ rear rotor set is best for Mazda CX-9 owners who need a no-frills, correct-dimension replacement for rear rotors and want modest rust resistance from the G-coating. It suits DIY installers and independent shops replacing both rear discs at once to restore braking balance.

It is less appropriate for drivers seeking performance rotors with cross-drilled or slotted faces, or for vehicles used in competitive or extreme towing conditions where specialty rotors would be preferable. Also check fitment information carefully if the vehicle has nonstandard hub or brake options.

Pros & Cons

Pros

• Direct OE-style fitment makes installation straightforward for the CX-9 rear hubs.
• Quality construction and premium G-coating give better resistance to surface rust compared with bare rotors.
• Sold as a matched pair so both rear rotors share the same wear characteristics after replacement.
• Vented design aids heat dissipation for typical daily driving and light towing.

Cons

• Some customers reported mixed experiences with braking feel and installation, so expectations should be realistic compared with OEM or premium performance rotors.
• Not intended for high-performance applications that require drilled or slotted surfaces.
