Wilwood 140-17936 Forged Dynapro Big Brake Front Brake Kits

This kit is configured for dedicated road racing on the 1990-2005 model year Mazda MX-5 Miatas. It requires 15" wheels designed with additional inside clearance to accommodate the larger than stock brake package. The four piston DPL/ST calipers used in this kit feature a forged aluminum body with a Type III Mil-Spec hard anodized, medium gray color finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. 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 sized for compatibility with OE power brake boosters and master cylinders, and are easily configured with manual brake conversions and balance bar pedals using appropriately sized master cylinders. Spec37 alloy, GT competition series 11.75" diameter 40 vane rotors are mounted to weight saving forged aluminum lug mount hats. 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 in the stock location, without modifications. This race winning 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.

Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
