Z26 Street Warrior Brake Kit - E9x 328xi

Product Details

At Turner, we know the E91 Wagon and E90 Sedan xDrive models carry extra mass that puts a heavy load on the braking system. As these cars age, caliper piston drag and seal failure become common, leading to a soft, unresponsive pedal and uneven pad wear. The KC4102-26 Street Warrior Kit is our recommended solution for a total hydraulic and friction reset.

The Z26 Carbon-Fiber Ceramic compound is the critical upgrade here. By reinforcing the pads with carbon fiber, PowerStop has created a friction material that resists compressibility and glazing even under the intense heat of spirited highway driving or mountain runs.

Pairing these with drilled and slotted rotors ensures your 328xi can shed heat far more effectively than with original blanks. The drill holes provide an exit for internal heat, while the slots constantly refresh the pad surface to maintain a clean contact patch. The addition of freshly remanufactured red calipers ensures your entire hydraulic system is operating at peak efficiency while providing that classic motorsport aesthetic. This is the definitive choice for the xDrive owner who wants a car that stops as sharply as it handles.
