Racing Miata Version 5 Big Brake Kit – FRONT ONLY
Our best version 5 Miata Front Big Brake Kit. Includes 11.75 inch rotors – your choice of good, better, or BEST rotors, front heavy duty stainless steel lines, Wilwood Dynapro 4 piston calipers with BP-20 pads, mounting brackets, everything you need to complete installation of the front big brake kit.
*** The 4 piston front caliper option in this kit uses the 7812 pad shape. Type “7812” into the search box on the upper left of our site to see all our pad options for this caliper.***
*** The 6 piston front caliper option in this kit uses the 6712 pad shape. Type “6712” into the search box on the upper left of our site to see all our pad options for this caliper.***
Our Version 5 Miata Big Brake Kit has evolved to an 11.75″ rotor – the largest that can be fit under most track day wheels – and now features the option for you of either the most affordable and lightweight Wilwood rotor replacements available anywhere, OR a high quality StopTech pillar vane rotor for excellent durability for performance fun use, OR the highest quality Performance Friction curved vane rotors for exceptional racetrack cooling and longevity.
Caliper options are Wilwood forged Dynapro 4 piston or 6 piston calipers. The 4 piston is the lighter choice and offers faster pad swaps (pads install from the top after removing a retaining clip). The 6 piston offers the largest pad volume for longevity, and the most rigid/heavy duty option, but comes with a little more weight and more time to swap pads (have to unbolt the caliper from its bracket – pads install from the bottom after removing the two slider pins).
Wilwood 32 straight vane Ultralight rotor – straight vane design, great for the average street user that wants BIG stopping power but doesn’t need the massive heat resistance or durability of our other rotor options. These are also the lightest of the three rotor options; good for those competing in autocross who are counting every ounce and who don’t mind replacing rotors more often than the heavier duty options. As a bonus, these cost less than $40 per rotor to replace!
StopTech pillar vane rotor – engineered to provide superior strength while reducing rotor weight and running cooler compared to simple straight vane rotors. The diamond shaped pillars provide brake pad surface stability as well as reduced rotating weight over rotors of similar strength. Airflow is also improved over straight vane rotors, allowing quick heat dissipation that results in greatly reduced fade. We recommend these rotors for those who want a high quality rotor for their street performance build or who are doing occasional track days or similar where the added cooling and durability set these rotors far ahead of the basic Wilwood rotors.
Performance Friction curved vane rotor – directional cooling vanes and the highest quality motorsport grade iron composition. The directional internal vanes work on the same principal as an air-impeller, designed to extract hot air. As the disc rotor rotates, it pumps air from the center outwards. The PFC rotors also use the highest quality iron and manufacturing processes. The bottom line is that these rotors usually last our track users four or more times longer than the Wilwood rotors (thus, the greater entry cost is paid back in rotor replacement savings with many of our track customers reporting YEARS of track use on one set of these rotors.).
All of the above friction rings share the same scalloped aluminum rotor hats which provide the greatest resistance to distortion for uniform disc expansion and added thermal protection for your bearings. Hats are anodized so they will look great for years to come.
