PowerStop Z26 Street Warrior Brake & Caliper Kit - X1 xDrive35i

Product Details

At Turner, we know the E84 X1 xDrive35i is essentially an E91 335i wagon on stilts. With that N55 power and xDrive weight, the factory single-piston sliding calipers are pushed to their absolute thermal limits. As the calipers age, piston drag and seal failure become common, leading to uneven pad wear and a soft, unresponsive pedal. The KC7021-26 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 a mountain descent.

Pairing these with 348mm drilled and slotted rotors ensures your X1 can shed heat far more effectively than with original blanks. 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 X1 owner who wants to maintain the "Ultimate Driving Machine" experience with modern reliability and massive stopping power.
