At Turner, we know that the E91 Touring and E93 Convertible carry significant additional weight over the standard sedan—especially when equipped with the xDrive drivetrain. This extra mass leads to accelerated brake fade and higher operating temperatures. The KC4105-26 Street Warrior Kit is specifically engineered to expand the thermal envelope of these heavier E9X variants.
The Z26 Carbon-Fiber Ceramic compound resists pad compressibility, providing a firmer and more communicative pedal during high-speed deceleration.
Pairing these with drilled and slotted rotors ensures your 328xi can shed heat far more effectively than with original blanks, preventing the "wooden" pedal feel that occurs when factory brakes heat-soak. 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 owner who wants their Wagon or Convertible to stop with the same authority as a standard coupe.
