StopTech 06-08 BMW Z4 (E86) / 06 M3 Front BBK w/ Silver ST-60 Calipers 380x32 Slotted Rotors

This StopTech Big Brake Kit is designed to enhance braking performance by maintaining factory bias while achieving shorter stopping distances, improved modulation, and reduced brake fade. The kit includes robust, fully forged ST-60 calipers with patented stiffening bridges, which contribute to their renowned rigidity, minimizing flex, vibration, and noise for a more confident pedal feel and even pad wear. The calipers are finished in silver. The kit also features larger-than-stock, 2-piece AeroRotors measuring 380x32mm, designed with patented internal cooling vanes for optimized airflow and lower operating temperatures. These rotors are slotted for enhanced initial bite and improved wet braking performance. StopTech Street Performance Pads are included, offering an aggressive street compound with excellent initial bite and moderate torque. Braided stainless steel brake lines are provided to replace factory rubber lines, offering a firmer pedal feel and consistent performance. Model-specific hardcoat anodized 6061-T6 billet aluminum mounting brackets and all necessary hardware are included for a precise and rigid installation. This kit focuses on a "Balanced Brake Upgrade" approach, where each component is engineered to work synergistically with the vehicle's hydraulic system, weight transfer characteristics, and tire contact patch to optimize braking torque distribution across all four wheels.
