Save $50 now on our newest rotor version of the best Miata big brake kit available. We designed our original FOUR WHEEL Miata Big Brake kit for the track users running lots of additional horsepower and needing additional stopping power. But for years the street guys asked for a Miata big brake kit that included slotted rotors front and rear that were already assembled to the hats to make installation easier. Also, folks wanted cast iron front and rear rotors. The version 3 Miata Big Brake Kit answers all these requests and is sold both here and by dealers such as Flyin Miata. Version 4 Miata Big Brake Kit goes another step and uses four DBA5000 rotors with Alumalite center hats made from light weight aircraft grade aluminum connected to directional slotted rotors with NAS bolts and lock nuts. The rotors use DBA's patented "Kangaroo Paw" ventilation technology. 'Kangaroo Paw' is a patented hi-tech disc rotor ventilation system,designed and manufactured in Australia by Disc Brakes Australia. The Kangaroo Paw design features a series of 144 diamond and tear drop shaped pillars and columns, individually spaced between the rotor faces. This system provides two key advantages. One advantage of this design is the ability to cool the rotor faster than ever before. This works on the same principal as an air-impeller, designed to extract hot air. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot-air out from within the internal areas of the rotor. The second advantage is the increased dimensional stability across the disc rotor, directly achieved by the individually spaced pillars and columns. These advantages increase the disc rotor s efficiency by as much as 20 per cent when compared to conventional rotor designs. A 20 per cent increase in disc rotor efficiency, directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder. These custom rotors also feature DBA's Thermal Stability Profiling (TSP). Thermo-Graphic paint markings (see above picture) tell you the peak temperature range you reached on track (which helps you fine tune your pad selection). DBA's AlumaLite hats provide the greatest resistance to distortion for uniform disc expansion and added thermal protection for your bearings. Includes: Wilwood Dynalite Forged 4 Piston Billet Aluminum Calipers in front, matching Stainless lines Front and Rear, Wilwood Q pads for front and Porterfield R4S pads rear, four aluminum hats and four rotors (10.75 inch rear, 11 inch front) fully assembled. Enough thermal capacity for any street Miata, track Miata, autocross and V8 Miatas! You will NEVER exceed the thermal capacity of this system. This Miata Big Brake Kit fits all 90-93 Miatas!
