Product Details
Upgrade the front-axle stopping power and pedal response of your executive open-top grand tourer while completely eliminating aggressive, messy factory brake dust. The Power Stop Z23 Evolution Sport Brake Kit is engineered as a direct bolt-on performance replacement for daily drivers, high-speed highway commuters, and roadster enthusiasts looking to maximize braking torque and thermal control across the front axle.
Focusing strictly on a front axle only upgrade (the standalone front counterpart to the comprehensive K8735 4-wheel performance package, and the silver zinc-plated alternative to the coated CRK8704 smooth setup), this kit replaces standard factory parts with premium cross-drilled and slotted performance rotors. The specialized front discs feature a massive 342.1mm diameter footprint. Precision-machined cooling holes maximize internal airflow across the structural venting vanes to drop operational temperatures fast, while rounded outer slots continuously sweep away boundary gases, water, and friction debris to guarantee a clean contact patch under heavy high-speed deceleration. Every rotor is finished with a defensive silver zinc-dichromate plating to actively prevent rust and oxidation along the un-swept hub hats and inner venting paths.
The rotors are paired with advanced Z23 carbon-fiber ceramic pads. This compound noticeably increases braking torque compared to traditional standard ceramic pads, providing a confident, immediate initial pedal bite without the harsh squeal or heavy black carbon residue common to original European factory semi-metallic compounds.
Key Features:
Z23 Evolution Sport Pads: Formulated with a proprietary low-dust carbon-fiber ceramic compound designed to noticeably increase braking torque while keeping luxury alloy wheels clear of dark, corrosive factory dust. Features multi-layer rubberized shims for virtually silent operation.
Drilled & Slotted Performance Rotors: Precision cross-drilled holes accelerate heat dissipation to minimize thermal distortion or fade, while sweeping slots maintain a clean pad face. Fully zinc-plated to ensure long-lasting defense against moisture and winter road grime.
Axle Matched: A focused front axle performance solution containing upgraded performance front pads, corresponding cross-drilled and slotted zinc-plated vented rotors, premium stainless steel installation clips, and a replacement front electronic wear sensor wire.
