Powerstop Z23 Evolution Sport Brake Upgrade Kit - Front & Rear - 1984-92 BMW 3

Product Details

The PowerStop Z23 Evolution Sport Kit (K4167) is the definitive "bolt-on" upgrade for the driver who wants a track-inspired look and feel with street-legal reliability. This comprehensive kit eliminates the guesswork of matching pads and rotors, providing a perfectly tuned system that works in harmony to dissipate heat and resist brake fade. The Z23 series is particularly famous for its "bite"—delivering immediate response the moment you touch the pedal. With its rugged construction and aesthetic appeal, this kit doesn't just stop your vehicle faster; it transforms the entire corner of your car into a statement of performance engineering.

Key Features

• Enhanced Thermal Management: The combination of drilled cooling holes and carbon-fiber pads allows the system to operate at much lower temperatures during heavy braking.

• Precision Fitment: Designed as a direct bolt-on replacement for factory hardware, requiring no modifications to your calipers or brackets.

• Consistent Friction Profile: The pads undergo a thermal scorched process during manufacturing for a faster break-in period and consistent performance right out of the box.

• Maximum Durability: Built to withstand higher operating temperatures than standard replacement kits, preventing rotor warping and pad glazing.

• Aesthetic Upgrade: The aggressive drilled and slotted pattern provides a high-end, sporty appearance that fills out the space behind open-spoke wheels.
