Power Stop K4135 Z23 Evolution Sport Front & Rear Drilled & Slotted Brake Kit with Carbon-Fiber Ceramic Pads

The Power Stop K4135 Z23 Evolution Sport Brake Upgrade Kit is a complete front and rear braking solution engineered to deliver a meaningful performance upgrade over factory brakes — without sacrificing everyday drivability. Everything needed for a bolt-on installation is included right in the box.

Z23 Carbon-Fiber Ceramic Brake Pads

The Z23 Evolution Sport brake pads are built with a carbon-fiber infused ceramic compound, manufactured using OE positive mold technology to ensure uniform friction density throughout each pad for consistent wear and reduced noise. Dual-layer rubberized shims provide noise insulation that outperforms plain steel shims, while a powder-coated backing plate resists rust and corrosion for extended service life. Each pad surface is thermally scorched at the factory to burn off residual manufacturing gases and resins, delivering a shorter break-in period and superior fade resistance right from the start. A high-temp ceramic-based brake lubricant and premium stainless-steel hardware kit are included.

Cross-Drilled & Slotted Zinc-Plated Rotors

Power Stop's drilled and slotted rotors are cast from G3000-grade iron and finished with a Silver Zinc Dichromate plating to resist rust and corrosion while providing a clean appearance behind open-spoke wheels. Precision drill holes maximize rotor cooling to keep brake temperatures in check during demanding conditions, while rounded slots continuously wipe away gas, dust, and debris — maintaining a clean, consistent contact patch for confident, smooth braking.
