Upgrade your daily driving confidence with the PowerStop Z23 Evolution Sport Front Brake Upgrade Kit, part number K7703. Designed for select 2016 Volvo XC90, 2017 Volvo S90, and compatible applications, this complete bolt-on system includes drilled and slotted rotors, carbon-fiber ceramic brake pads, stainless-steel installation hardware, and high-temperature ceramic lubricant. The components are engineered to work together for improved stopping power, consistent performance, and straightforward installation without vehicle modifications.
The PowerStop Z23 carbon-fiber ceramic brake compound delivers stronger braking performance than traditional ceramic pads while helping reduce visible wheel dust. On-vehicle third-party testing in Los Angeles validated an average of 30% less dust than original equipment pads. Multi-layer rubberized shims help provide virtually noise-free braking, making this kit well suited for everyday driving and commuting.
Drilled and slotted performance rotors promote efficient heat dissipation to help maintain smooth, reliable braking under repeated use. Each rotor is zinc plated for enhanced protection against rust and corrosion, supporting long-term appearance and durability. The included stainless-steel hardware and ceramic brake lubricant help complete the installation with the essential components needed for a dependable brake upgrade.
PowerStop created the Z23 Evolution Sport kit as an accessible performance improvement for stock braking systems. With matched pads, rotors, and hardware in one package, the K7703 kit simplifies the upgrade process while delivering cleaner wheels, reduced noise, improved cooling, and enhanced braking response.
