After much debate on the forums, we at MiataSpeed decided to further investigate the differences between the two packages that come standard with the ND Miata.  Mazda lists two different part numbers.   Non-Brembo N251-33-251Brembo NA5F-33-251A All measurements were referenced with the use of a surface plate.However, based on our measurements, we have not found any difference between the two rotors dimensionaly.  The only difference we have found were the internal cooling vanes of each rotor.   Brembo on the left, Non-Brembo on the right. Each rotor is 280mm x 22 mm Offset is the same. Vane design The Non-Brembo has a...

Long awaited results are here! The below results are from our own Custom built tune, not the CARB tune. We should be getting the CARB tune shortly so we will post those results as well! Before we dive in to the results and details, we'd just like to remind everyone that every dyno reads differently. Whether it's a different brand or model and any correction factors on top of that, numbers can be quite different from dyno to dyno. What matters is the gains on the same dyno. Without further ado, the dyno chart! On our dyno, the stock car baselined...

In a perfect combination of suspension engineering and world class driving by Ian Stewart, we have taken First Place at the SCCA STR Solo National Championships! After switching from 949 Xidas to our Ohlins FPSpec Long-Stroke DFV, the level of the car was instantly elevated and culminated in a big win for Ian and for us! That makes it the first Mazda to win STR class in 10 YEARS! Ian took the class by storm, winning by a margin .323 seconds. Video of winning drive below! "Autocross is one of the motorsports that demands to most out of shocks. Often...

We have a fair bit of experience with the carbon buildup problems of Direct Injection systems in other platforms, we had always been curious if Mazda had come up with any interesting solutions to combat the carbon buildup that happens on the intake valves and intake tract. Excessive carbon buildup can cause poor sealing, hesitation, poor idle, etc.  When we cracked everything open for the Edelbrock E-Force Supercharger Install, we were eager to see what we would find. The answer to our question was...nope. Our shop ND only has 19,000 miles on the clock and we were a bit surprised at what we found....

After their great success with the BRZ/FR-S E-Force Supercharger kit, Edelbrock decided to tackle the ND Miata platform, making this the second supercharger that they have ever made for an import vehicle. Bringing decades of engineering expertise and manufacturing prowess to the table, they set out to make the most complete supercharger solution possible for the 2016+ ND Miata and we are proud to be one of their launch partners! The Edelbrock Supercharger comes securely strapped to a pallet to insure safe transit to the customer. There's the option of liftgate delivery for those who do not have forklifts, but...
