The first four complete Miata brake packages below are stock size Miata brake upgrades that contain upgraded Miata rotors, stainless steel brake lines and pads. Below those first four kits are Good-Win Racing's big selection of Miata Big Brake Kits and Miata Big Brake Kit options and accessories. The many choices in our Miata big brake kits are broken down into four versions.
Version one of our Miata Big Brake Kit is a budget kit that gets you substantial additional thermal capacity with front 11 inch rotors and 10.75 inch rear rotors at a budget price but includes steel rotors in the rear and requires the user assemble the two piece rotors. Version 2 adds cast iron rear rotors. Versions 3 and 4 add pre-assembled two piece rotors with substantially upgraded connecting hardware and corrosion protection. Version 4 is our best Miata Big Brake kit and adds better venting function and thermo-graphic temperature monitoring. See the descriptions of the Miata Big Brake Kits below for additional information.
Note these Big Brake Kits need 15 inch wheels, but not all 15 inch wheels clear (contact us for template by email).

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.
