Product Details
The PowerStop KC4104-26 is the definitive "all-in-one" performance solution for the BMW 328xi enthusiast. This massive Front and Rear kit is designed to revitalize your E9X xDrive chassis by replacing tired, potentially sticking factory calipers with vibrant, red powder-coated units and upgrading to carbon-fiber-infused friction technology. This kit provides the "bite" and thermal management necessary for the added weight and grip of the all-wheel-drive system.
The Performance Package
Z26 Carbon-Fiber Infused Ceramic Pads: A massive leap over standard ceramic replacements. The carbon-fiber reinforcement creates a high-torque bite that remains stable up to 1500°F, ensuring your 3-series stops shorter and harder without the corrosive black dust of OE pads.
Red Powder-Coated Calipers: Each kit includes a full set of remanufactured OE-spec calipers. These are pressure-tested and treated with a high-temperature red powder finish that stands out behind your wheels while resisting road salt and chemicals—a common issue for AWD BMWs driven in winter climates.
Drilled & Slotted High-Carbon Rotors: Specifically engineered to combat heat-soak. These rotors feature precision-drilled holes for maximum cooling and rounded slots to evacuate gas and dust, maintaining a consistent pedal feel even under repeated hard stops.
Silver Zinc Protection: Every rotor is treated with a Silver Zinc Dichromate plating to protect the hubs and internal vanes from rust and oxidation, keeping your BMW looking "OEM-plus."
Total Refresh: Includes front and rear pads, rotors, red calipers, and premium stainless steel installation hardware.
