AERO6 Big Brake Front Brake Kit (Race)

This kit is configured for dedicated road racing on all 2001-2006 BMW E46 M3 models. The AERO6R/ST six piston calipers used in this kit feature a forged aluminum body with a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. This latest model of the AERO6R/ST calipers features a wider than standard body that accepts 20mm thick pads to add volume for longer service life. Thermlock® pistons are used to reduce heat transfer from the pads to increase fade resistance, and to extend service life by decreasing temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish. Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls. The kit is also easily configured with manual brake conversions to balance bar pedals using appropriately sized master cylinders. Spec37 alloy GT competition series 14.00” diameter directional vane rotors are dynamically mounted to the OE hubs with weight saving forged aluminum hats. As is with the calipers, the hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces. Unsprung and rotating weight are minimized while providing high cooling efficiency and rugged durability with thermal stability in sustained high heat competition. Mounting brackets, including all premium grade fasteners, secure the calipers to the spindles in the stock location with minor modifications to the spindle dust shield as illustrated in photo 1 on page 4 of the assembly instructions. This championship proven system is completed with high temperature, high friction, endurance compound race pads selected specifically by application. Stainless steel braided flexlines are included in each kit to complete the installation.
