Wilwood Mazda MX-5 Miata Front Brake Package, Red Dynapro 6 Calipers and 11-Inch Slotted Rotors

Red six-piston Dynapro calipers and slotted Spec-37 rotor rings provide this Miata front conversion. The kit retains the documented hubs through aluminum hats, while the flexible hydraulic lines are separate. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility

Check the Miata sports-suspension and 2001 VIN qualifications against DS1022 and the application rows. Confirm early-year coverage where the broader instruction heading differs, together with the actual wheel profile.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Mazda Miata. Application distinctions include All except Sports Suspension; w/ Sports Suspension from VIN 206467; w/ Sports Suspension to VIN 206466; w/ Sports Suspension.

The application list covers 1991–1997 and 1999–2000, plus 2001–2005 with the stated sports-suspension qualifications. The 2001 sports-suspension rows split at VIN 206466/206467; do not collapse these into an unsupported 1990–2005 direct-fit claim.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.
