Wilwood Forged Dynalite ST Front Hat Kit 11.00in GT Rotor Road Race 95-05 Miata

The components in this kit have been selected to deliver consistent start to finish performance on vehicles built for dedicated road course competition. No detail has been overlooked. Forged aluminum Dynalite-ST calipers, fortified with Thermlock® pistons and internal knock-back damping springs, provide high efficiency clamping force, unsurpassed heat management, and the piston retraction control that all contribute to a firm and consistent pedal through any event. Oversized 11" diameter Spec37 alloy GT series 72 vane two-piece rotor assemblies mount to the OE hub with aluminum hats adding overall system brake leverage, cooling capacity, and thermal stability in this compact yet sturdy weight saving configuration. The performance package is capped with high friction, high temperature, and long wearing Wilwood PolyMatrix H compound race pads. All premium grade fastener kits include rotor bolts and caliper to mount bracket bolts that are pre-drilled for safety lock wire.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Reference Information

Disc Brakes, Front, DynaPro, Slotted Rotors, 4-Piston Gray Calipers, Mazda, Miata, Kit

Wilwood's forged DynaPro Big Brake front brake kit (140-14316) is configured for dedicated road racing on the 1990-2005 model year Mazda MX-5 Miatas. It requires 15 in. wheels designed with additional inside clearance to accommodate the larger-than-stock brake package. The 4-piston DP/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 11.00 in. diameter 72 vane rotors are mounted to either the OE hubs or Wilwood racing ProHubs, with weight-saving forged aluminum 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.
