We made a diffuser for our own car, a V8 miata built for lap records. We ran the diffuser in CFD and set it to kill.  We gave zero cares for OEM body limitations, as we only wanted the diffuser to work and win championships.

Fast forward to today, it's a well-tested piece that we know performs well.  We were asked repeatedly to make another for sale and we refused. Well, we had a tire fail at Daytona which killed our diffuser.  As we're forced to make another, people have heard about this and convinced us to make a limited run. We now will offer these to the public for a limited time. Only 6 to sell, after which the sale is over and the part will be discontinued. 

Diffusers measurements

  • Have .25" locating holes along each rib for easy mounting 
  • Optional bolt-in subframe plate.
  • 57" long,  35.5" wide, and 10" tall.  
  • Made from a mixture of 5052, 6061, and 3003 aluminum. 
  • Built-in CFD, tested on track.  


Pay attention to this:
The diffuser mounts to an optional plate as seen in pictures. The plate bolts to the bottom of your subframe and is secured to the diffuser with .25" rod. The rods will be included with the mounting plate.
Trunks will need to be cut, along with the factory tow hooks. They will not fit otherwise.
