Thank you. You have rated this product.

REAR only of our best version 4 Miata Big Brake Kit, made for use of 1.8 liter calipers that started in 94. Normally used 94 and newer but can be used on earlier miata if you have those later calipers from 94+ 1.8 liter (but not the SPORT rear that were optional starting 2001). Includes our famous 10.75 version 4 TWO-PIECE rotors, heavy duty stainless steel lines, brake pads, mounting brackets, everything you need to complete installation of the rear big brake kit.

Our Version 4 Miata Big Brake Kit goes another step beyond our lesser kits 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 (notice more connection points than the lesser kits and higher grade hardware, higher grade rotors, higher grade hats). 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 Wilwood kits. 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!).

REVIEWS

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
