POWERSTOP Rear Z17 Brake Pad and Rotor Kit - OE Replacement

In this review of the POWERSTOP KOE5381 Rear Autospecialty kit, the bottom line is simple: it is a practical, OE-style refresh for owners of compatible Hyundai and Kia sedans who want reliable daily stopping power without upgrades aimed at performance driving. The kit combines Z17 Evolution ceramic pads and Autospecialty stock replacement rotors into a bolt-on package that aims to restore original rotor feel and provide quiet, low-dust braking for routine driving. Installation is straightforward for anyone with basic mechanical skills, and the included hardware simplifies fitment for the specified model years.

Key Features

• Complete rear kit: Includes two rear Autospecialty rotors and one rear Z17 ceramic pad set with hardware to cover a full axle replacement in one purchase, simplifying the service job.
• Z17 ceramic formulation: The pads use a ceramic compound that is engineered to deliver consistent, OE-like stopping performance while resisting excessive brake dust and common noise issues.
• Autospecialty rotors: These stock replacement rotors are designed to restore original rotor performance and offer an easy, bolt-on swap for the listed vehicles.
• Hardware included: Stainless-steel hardware ships with the kit so brake pads and rotors can be installed without sourcing additional parts, saving time and effort.
• Vehicle specific fit: The kit is packaged for specific Hyundai and Kia model years to reduce compatibility guesswork when replacing rear brakes on those cars.

Who It's For

This kit is best for owners of 2012-2017 Hyundai Azera, 2011-2015 Hyundai Sonata, and 2011-2016 Kia Optima models listed who need a direct, OE-style rear brake replacement. It suits drivers who want a cost-effective, all-in-one solution that restores everyday stopping power and minimizes brake dust and routine maintenance time.

It is not aimed at drivers seeking high-performance or track-oriented upgrades, nor is it intended for cars with nonstandard aftermarket parking brake setups. Buyers concerned about long-term rotor durability or who have had previous fitment issues should verify rotor dimensions and parking brake compatibility before ordering.
