NA/NB Miata V3 Rear Diffuser Group Buy

It's here folks, the R Theory Motorsports V3 Rear Diffuser has landed and we're ready to begin our initial group buy. The V3 was designed with the simple and practical looks of the V1 in mind. Meanwhile incorporating a curved profile similar to the V2, while being taller and more aggressive than the V2. The advantage of designing a diffuser with a curved profile over a simple wedged type profile comes down to one thing, surface attachment. In layman's terms, it allows the air to more effectively follow the upward slope of the diffuser thus creating a low pressure region under the car. Low pressure under the car is what creates downforce.

A mild bumper cut will be required on the NA, and possibly on the NB. We will be test fitting on an NB and updating this page before we open up to taking deposits. You can expect the V3's mounts to be the same reliable and rigid mounting locations just like our previous models.
