TRQ Rear Brake Rotors Set Vented G-Coated - Direct Fit Replacement

In this review of the TRQ Rear Brake Rotors Set Vented Premium G-Coated, the bottom line is simple: this pair is a straightforward OE-style replacement for owners of 2015-2020 Chevrolet Colorado and GMC Canyon who want reliable rotors with improved corrosion resistance. The reviewer found the set to be a direct fit and appreciated the factory-like dimensions and the G-coating that helps limit surface rust, making these rotors a practical choice for drivers who need a dependable rear rotor swap without expensive performance upgrades.

Key Features

• Direct Fit: Designed to match original mounting points so installation follows the vehicle's OE specifications and typically requires no modification.
• G-Coated Protection: A premium G-coating helps reduce surface rust on the hat and outer areas, extending the rotor's appearance and service life in wet climates.
• Two-Piece Set: The kit includes both rear driver and passenger rotors so both sides can be replaced at once for balanced braking performance.
• Vehicle Specific Fitment: Clear compatibility with 2015-20 Chevrolet Colorado and GMC Canyon ensures buyers can check fitment before purchase to avoid fit errors.
• OE Replacement Dimensions: Built to the listed nominal and discard thickness values so the rotors behave like the original parts under normal driving loads.

Who It's For

This set is aimed at Colorado and Canyon owners who want an economical, reliable replacement that mirrors the original equipment shape and mounting. It is a good choice for DIYers and independent shops replacing rear rotors as routine maintenance or when refreshing the braking system without changing pads or upgrading to slotted or drilled performance rotors.

Those seeking high-performance track use, specialty coatings for extreme climates, or rotors with cross-drilled faces should look elsewhere; this set focuses on correct fit, corrosion resistance from the G-coating, and value rather than motorsport braking enhancements.

Pros & Cons

Pros

• Quality construction that matches OE dimensions for predictable brake feel and fitment.
• G-coating provides visible rust resistance on non-friction surfaces, improving long-term appearance.
• Sold as a matched rear rotor set so both sides can be renewed together for consistent braking.

Cons

• Not a performance rotor - customers seeking enhanced cooling or aggressive bite will need a different design.
• Some buyers report mixed experiences with initial surface condition and installation ease, so careful inspection before fitting is advised.
