TRQ Rear Brake Rotors Set Solid G-Coated Compatible with 2006-2011

In this review the TRQ Rear Brake Rotors Set is evaluated as a direct-fit replacement for 2006-2011 Buick Lucerne and compatible Cadillac DTS models. The bottom line: this two-piece solid rotor set is aimed at DIY mechanics and owners who want an OEM-style, rust-resistant replacement that installs with minimal fuss. The kit includes one rear driver side and one rear passenger side premium G-coated rotor, and TRQ backs the part with a large library of DIY videos and fitment guidance to help ensure correct compatibility and straightforward installation.

Key Features

• Complete rear pair: Includes both rear driver and passenger side premium G-coated rotors so the job can be done without sourcing a matching rotor separately.
• G-coating for rust resistance: The premium G-coating helps limit surface rust during storage and early service life, improving appearance and longevity compared with uncoated cast rotors.
• Direct fit design: Built to be a direct replacement for specified 2006-11 Buick Lucerne and Cadillac DTS 5-lug models, reducing the need for modification and saving installation time.
• DIY guidance available: TRQ provides a large catalog of DIY videos and fitment resources so installers can "view before they do" and confirm proper steps for a safer installation.
• Measured tolerances: Nominal and discard thicknesses, bolt hole diameters, and center hole sizes are provided to match original mounting points and ensure proper fitment.

Who It's For

This rotor set is best for owners of 2006-2011 Buick Lucerne and Cadillac DTS (with 5-lug wheels and without heavy duty brakes) who prefer a like-for-like, factory-style replacement and want to perform the brake service themselves or with a trusted local shop. It suits drivers who value rust protection and straightforward swap-in parts that avoid machining or complex hardware changes.

It is not aimed at performance drivers seeking slotted or cross-drilled rotors, nor is it intended for Cadillac DTS vehicles equipped with heavy duty brake packages or nonstandard hub variants. If you need upgraded cooling, noise reduction features, or specialized rotors, consider other aftermarket options.

Frequently Asked Questions

Are these rotors a direct replacement for my 2009 Buick Lucerne?
They are compatible with 2006-11 Buick Lucerne rear driver and passenger side applications; confirm fitment with your vehicle details and the seller fitment chart.

Do the rotors come with hardware or pads?
The kit includes the two rear rotors only; mounting hardware and pads are not included and should be reused if in good condition or replaced separately.

Will the G-coating prevent all rust?
The G-coating reduces surface rust and improves appearance, but it does not make the rotor corrosion proof under all conditions; normal wear and environmental exposure will still affect rotors over time.
