Goodwin Racing Miata Big Brake Kit, FRONT ONLY Version 4.

DESCRIPTION

Front only of our best version 4 Miata Big Brake Kit. Includes front 11 inch version 4 rotors, front heavy duty stainless steel lines, Wilwood calipers with pads, mounting brackets, everything you need to complete installation of the front big brake kit.

*** As of 6/28/16 we have upgraded this kit to include the newer and stronger DynaPro 4 Piston caliper (olded kits used the Dynalite 4 piston). The front calipers in this kit use 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.***

Our 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 version 4 rotors use DBA's patented "Kangaroo Paw" ventilation technology. 'Kangaroo Paw' is a patented hi-tech disc rotor ventilation system, designed and manufactured by Disc Brakes Australia for Good-Win Racing LLC. 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 of better cooling and better surface stability increase the disc rotor 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. The bottom line is that these rotors usually last our track users three or four times longer than the rotors in our version 1 and 2 kits, and nearly double the life of even the version 3 kit rotors (thus, the greater entry cost is paid back several times in rotor replacement savings with many of our track customers reporting YEARS of track use on one set of these rotors.). These custom rotors also feature DBA's Thermal Stability Profiling (TSP). A bonus feature is Thermo-Graphic paint markings that indicate the peak temperature range you reached on track (which helps you fine tune your pad selection).

Also, DBA's AlumaLite hats provide the greatest resistance to distortion for uniform disc expansion and added thermal protection for your bearings.

Brian's Application Notes: You get what you pay for...and EVERYTHING in our version 4 kit is much more stout than in our discount $599 Wilwood kit. The hats are far superior with 10 connection points to the rotor using NAS fasteners (compared with 6 connections to the rotor in our Wilwood discount kits). The brackets are several times stronger, the rotors are MUCH higher density DBA5000 rotors that will last several times longer than the Wilwood rotors, the rotors include thermographic side markings like those used in Formula One so that you can track your peak temps and better select pads, the rotors cool MUCH more effectively thanks to the patented design features discussed above. Finally, the lines are custom made for a direct fit and don't need the numerous adapter fittings used by the Wilwood kit (skipping adapters means less chance for brake fluid leaks!).
